Lada Kalina fuel pump fuse where is it located

The gasoline pump is an integral part of the power system of a gasoline engine. In order for the pump in the Lada Kalina model to function uninterruptedly, there must be a working fuel pump relay in its electrical supply circuit.

The pump takes in a portion of fuel, which is traditionally located in the tank. In Lada Kalina, this container with gasoline is located in the rear of the body. There are special pipelines as lines that transport fuel not only to the ramp with injectors, but also back to the tank. Using a pump, a certain amount of pressure is generated in the fuel rail, which allows the injectors to spray gasoline in the form of a torch (the so-called “fog”). The fuel pump fuse also plays an important role.

Photo where the fuel pump relay is located on the Lada Kalina

An integral part for the operation of the Lada Kalina is a gasoline pump. For safety and control, a fuel pump relay is used, but not everyone knows where it is located. In addition to the classic placement in the tank, the Lada Kalina pump is located at the rear of the body.

The video shows where the relay is located. A situation is considered when the car does not start due to problems with the relay.

Troubleshooting the Kalina fuel pump

If the electrics are working correctly, the fuel pump remains the object of close study. Replacing the fuel pump assembly is an extreme, and not at all mandatory, measure.

Electrical diagram for connecting a fuel pump

If the fuel pump does not turn on during normal electrical operation, remove the device to check the fuel pump. To check the functionality of the fuel pump, you need to remove the cover, which is located in the rear of the car, and remove the unit itself.

If the pump does not pump or pumps intermittently, it may be necessary to replace the Kalina fuel pump mesh. We remove the cover, disconnect the hoses and wires, use screwdrivers to press out the retaining ring and gain access to the pump. The device itself is located in the gas tank and takes gasoline directly from the tank.

Routine work, which would include replacing the mesh, is not specified in the operating instructions for the Lada Kalina. Repairing the fuel pump in order to replace the mesh should usually be carried out after 50 thousand kilometers, since the fuel at Russian gas stations is generally of low quality.

During dismantling, this can be assessed visually; the mesh turns from white to dirty brown interspersed with mechanical residues of metal, dirt and oil. At the bottom of the glass, when dismantled, you can see solid particles of unknown origin, which could only get into the tank when refueling.

There is also the opinion of some experts about the possibility of washing the mesh without replacing it. But taking into account the cost of this part, which does not exceed 100 rubles, the feasibility of flushing during the rather complex procedure of removing and installing the fuel pump is highly questionable.

Separately, it is worth pointing out the culture of repair work: after disassembly, all parts must be cleaned of dirt and foreign impurities, thoroughly washed and installed in their original place without the use of excessive force. When replacing the mesh, it is advisable to replace the fine filter, which is located in the rear right wheel arch near the jack cup. Routine work to replace the filter is provided for during maintenance every 30 thousand km.

When pumping gasoline to the nozzle, 2 more grids are installed along the way to clean the fuel. One is located in front of the fuel pressure regulator, and the last cleaning line is installed before the injector inlet. But before these filters, gasoline arrives in a dirt-free state and fault diagnosis based on these barriers is practically not carried out, due to the low probability of the need for replacement.

The fuel system of the Lada Kalina car is a reliable and well-functioning combination of units that can ensure uninterrupted operation of the car for a long period of time with timely and correct maintenance. They include a mandatory replacement of the fine filter every 30 thousand km and, highly desirable, replacement of the fuel pump mesh after approximately 50 thousand km.

Where is the fuel pump relay located?

The relay is located in the additional fuse box. This block is located to the left of the passenger and is closed with a decorative cover, which is attached to one self-tapping screw.

• The relay is located on block 2 near the dashboard on the right.
• fuse is located under the gearbox cover.

The fuel pump fuse is marked with an arrow.

The self-tapping screw is marked with an arrow.

Removing the bolt securing the mounting block.

Before starting work, we recommend that you ALWAYS remove the terminal from the battery. After checking the system and replacing the necessary elements, you should start the engine and check the functioning of the car and the pump.

Replacing the fuel pump Kalina

Before replacement, read the operating manual to learn the location of the fuel system element, the specifics of the adjacent fuel lines and the types of fasteners. When working, it is important to follow the outlined algorithm so as not to disrupt the functioning of the fuel supply system. Damage to the fuel line or improper assembly of the fuel module can lead to engine damage and even a car fire.

To carry out the work, the car owner will need:

• pliers;
• hammer;
• screwdrivers for flat and Phillips slots.

Sequence of replacing the fuel pump Lada Kalina

Before starting work, you need to “de-energize” the Kalina by disconnecting the battery terminals. Repair procedures should be carried out away from fire and places where sparks could be generated.

1. We dismantle the rear seat and floor trim;
2. Under the seat there is a fuel tank cap secured with 4 “cross” bolts. Unscrew;
3. Now the car owner has access to the top cover of the fuel pump;

4. Now you need to “unhook” all the plugs and fittings from the pump. To remove the power plug, press the latch upward and pull the plug to the side. The power plug itself is located on the left side of the fuel pump cover;
5. To remove the fittings, you must use pliers. The locking clamp is pressed out by hand, after which the fitting itself is removed using pliers. The main thing is not to confuse the fittings: the lock on the top is green, the lock on the bottom is metal;
6. After dismantling the fittings, clean the fuel pump cover as much as possible - dirt will not get into the gas tank;
7. Removing the fuel pump cover retaining ring: take a flat-head screwdriver, place it against the outline of the ring and lightly tap it with a hammer so that the ring moves clockwise. The latch should pop out and the cover will be accessible;

8. Open the cover and carefully pull the pump up so as not to damage the adjacent elements. Additionally, make sure that no sand gets into the tank;

9. We take the new pump and carefully immerse it in the technological hole. We attach the lid. Next, assembly is carried out in reverse order.

After the repair, you need to start the Kalina and drive for a few minutes. During operation, it is necessary to check the operation of the internal combustion engine in different speed ranges, at idle speed; You also need to be attentive to various noises in the fuel tank.

Peculiarities

The fuel system requires the use of high-quality gasoline and periodic maintenance. For prevention, you should change the filter and pump mesh to remove debris.

The filter is located behind the right arch, near the jack cup.

. The manufacturer advises making a scheduled replacement every 30 thousand km .

About work culture and regulations

VAZ 2114 does not click the fuel pump relay, how to diagnose a breakdown, pump repair, catalog numbers The
LADA Kalina fuel system (and not only) requires cleanliness of both the gasoline itself and the components involved in its supply to the engine. All dismantled parts of the system must be perfectly cleaned and washed before reinstallation. When replacing the mesh, we also recommend replacing the filter used for fine fuel purification. Where is this filter located? It is located inside the right stern wheel arch near the jack stand cup. According to the regulations, this element requires replacement no less than after 30 thousand kilometers.

Note that there are two more mesh filters along the fuel path in the circuit, one of which is installed in front of the fuel pressure regulator, and the second directly in front of the injectors. These filters “take over” fuel that has already been practically purified in the preliminary stages, so the need to replace them is extremely rare.

Lada Kalina - fuse and relay blocks

Lada Kalina 1

The first generation was produced in 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012 and 2013 under the internal serial numbers
VAZ-1117, VAZ-1118, VAZ-1119
with sedan, hatchback, and station wagon bodies. In this article we will show a description of fuses and relays of the 1st generation Lada Kalina with block diagrams and photographs. Note the fuse responsible for the cigarette lighter.

The design of the blocks and the purpose of the elements in them may differ from those presented and depend on the year of manufacture and level of equipment of your Lada Kalina. Check the description with yours, printed on the back of the protective cover, or other technical documentation.

Main block

The main block with fuses and relays is located under the instrument panel on the driver's side, behind the protective cover.

3. 15A - Fuel pump, viburnum fuel pump fuse.
4. 15A - Constant power supply circuits of the controller (ECU)

Possible causes of fuel supply system failure

The fuel pump on Kalina is electric. The use of this design and operating principle is justified by a number of advantages. These are simplicity and reliability, compliance with the required characteristics in terms of fuel supply volumes and a high level of safety ensured by turning off the system when the engine stops running.

On the other hand, for high-quality work you need excellent gasoline and cooling of the fuel pump, and the process is also accompanied by an increased noise level.

1. As a rule, poor quality gasoline and dirty filters lead to incorrect operation of the gasoline pump or its failure.
2. If there is no response from the engine when you turn the ignition key, the problem may be due to a broken fuel pump.
3. Since the main unit of the fuel system is powered by current, to troubleshoot it is necessary to check the electrical circuit going to the fuel pump.

First block: location, what it consists of

The first system is located under the cover, next to the speed switch, slightly below the ashtray. Knowing where the Kalina fuel pump fuse is located, you can troubleshoot many problems. To pry off the cover, just use a flat-head screwdriver.

The numbers in the image correspond to the numbering: 1. Power circuit; 2. Fuel pump; 3. A circuit designed to continuously power the ECU; 4. Connector necessary for diagnosing the condition of the ECM. If the Kalina fuel pump fuse stops working, you need to carefully remove it using tweezers or another device, then insert another one. When performing these manipulations, the battery must be disconnected.

Tips for motorists

The electric fuel pump, located in the gas tank of a Lada Kalina passenger car, can be considered the heart of the fuel injection engine power system. It is he who creates the necessary pressure in the ramp, the magnitude of which determines the operation of the electromagnetic injectors. The controller controls turning the fuel pump on and off. When the driver turns the key to the “ignition on” position, voltage is supplied to the fuel pump terminals for 3-5 seconds through the main relay. And as soon as the engine crankshaft begins to rotate, then, based on the signal from the DPKV sensor, the controller turns on the fuel pump relay and the voltage to its terminals goes through the contacts of this relay.

As you know, all electrical circuits in a car’s electrical wiring are protected by fuses, and if the fuel pump does not want to turn on, then they are the first to be checked. You can find a fifteen-amp fuse that protects the fuel pump circuit in the additional mounting block located next to the cigarette lighter. In order to open its cover, you will need a flat-head screwdriver. This block has four fuse slots. If they are in the first, second and third sockets, then you will need to check the middle fuse, since it is the one that protects the fuel pump circuit.

Having found out that this fuse is intact, the next step is to check the fuel pump relay. It is located behind the air duct cover located at the front passenger's feet. To remove it, you will have to unscrew one screw. Next, unscrew the nut securing the L-shaped metal plate and pull it out along with the four relays attached to it. The fuel pump relay is attached to the bottom of the plate, and the middle one of the three that is on the top of the plate is called the main relay. We check the functionality of the relay by replacing it with a known-good relay.

If checking the fuse and relay did not give the desired results, then by applying voltage directly from the battery terminals to the fuel pump terminals (gray wire plus, black wire minus) we check whether the fuel pump will work. If it turns on, then the fault will need to be looked for either in the absence of contact in the wire going to ground, or in a break in the wire going from the fuel pump relay to its block. A break in the gray wire is possible at the feet of the rear passengers, since the harness of 4 wires to the fuel pump block goes under the carpet, in the middle of the cabin.

The fuses and relays for the fuel pump and engine cooling fan are not located where the main fuses are, but in another place, or rather even in two. One is located near the gear lever under the ashtray.

The lid opens easily and simply, you just need to pry it with a flat screwdriver.

Let's take a closer look at what each element looks like.

Number 1 is the power circuit of the main relay, number 2 is the fuel pump, 3 is the constant power supply circuit of the ECU, 4 is the connector for ECM diagnostics.

If one of the fuses fails, you need to remove it and insert a new one. The battery must be disconnected.

The next fuse box is located on the right side of the panel near the heater duct. More details can be seen in the picture.

First, unscrew the self-tapping screw, it is located in the corner on the right, and then remove the cover.

In order to remove the relay block, you need to use a 10mm socket or open-end wrench.

Then carefully move the wires and pull out the fuse box. I would like to note right away that it is not very convenient to pull it out; the wires get in the way; after removal it looks like it is shown in the picture.

In this mounting block, number 1 is the switch on of the engine cooling fan (low speed), number 2 is the main relay, number 3 is the switch on the engine cooling fan (high speed), number 4 is the fan fuse, number 5 is the fuel pump switch relay. .

If one of the fuses or relays fails, replace it with a new one. We reassemble in reverse order.

Second system: where is it located?

The remaining Kalina fuel pump relays are located on the right side of the dashboard, not far from the air duct, also under a special cover.

First you need to remove the corner screw, then open the cover completely and remove it.

To remove the Kalina fan relay, you need to use a ten-socket socket wrench.

Then you need to carefully remove the wires, remove the unit and the Kalina cooling fan fuse. This is difficult to do, since you need to avoid damaging the wires. Upon completion of removal, the block will look as shown in the picture.

The presented unit includes the following elements: 1. Turning on the cooling fan (low speed); 2. Main relay; 3. Turn on the cooling fan (high speed); 4. Engine cooling system fuse; 5. Fuel pump relay. Now you know where the fuse for the fuel pump on Kalina is located.

Troubleshooting pumps

Now let's move on to consider the situation when the reason lies directly in the fuel pump itself. Replacing a unit is a drastic measure that can be avoided in almost the vast majority of cases.

Scheme

1. To check the LADA Kalina pump, you will need to dismantle it.
2. Access to the device location is provided through the rear of the cabin. To do this, you will need to remove the rear seat cushion.
3. The pump module is closed with a special cover; when removing it, you will need to remove the fixing fasteners.
4. When the ignition is turned on, the pump may not pump at all or supply fuel intermittently. If this is present, the device requires maintenance or replacement.
5. The further dismantling process involves removing the cover and disconnecting the pipes.
6. Now you can unscrew the locking ring, after which you need to carefully remove the pump from the cavity of the fuel tank.
7. We carefully inspect the dismantled unit for clogging of the filter present in its module, which is made in the form of a mesh. If it is not very clogged, then it can be washed, but when there are breaks and a high degree of contamination, then no alternative replacement is required.

This type of routine maintenance is not covered by the Lada Kalina operational manual. Despite this, the mesh on the pump should be replaced every 50 thousand km of the distance traveled. Such experience has the right to life due to the insufficient quality of domestic fuel.

Determining the need to replace the pump filter component is not difficult. As noted, this is done through visual inspection. Usually the mesh contains a dirty-brown mixture, which includes metal particles and other debris. The bottom of the pump assembly cup is often littered with solid particles of various natures.

Oil change in Kalina

Regarding the previously mentioned possibility of washing the mesh, many experts have a negative attitude towards this practice. Compared to the labor costs of dismantling the pump, the cost of the mesh itself is quite insignificant - about 100 rubles. It would be more rational and correct, in our opinion, to replace it, the main thing is to know where it is.

Differences in electronics of Lada Kalina 1 from Kalina 2

These two cars, despite their external similarities and common base, have different electrical wiring structures.

The second generation used Renault's developments, which explains the appearance of a body electronics unit, like on the Lada Vesta. In addition, these cars received completely different mounting blocks and their location.

The difference in the mounting blocks is also explained by the appearance on the Lada Kalina 2 of an automatic transmission, climate control and heated windshield. In addition, almost all trim levels now have DRLs. Therefore, diagnosing faults related to blown fuses on these machines is carried out differently.

Checking the fuel pump of a carburetor car (mechanical)

Mechanical fuel pump - diagram

To check the operation of the fuel pump, you should:

1. Remove the fuel hose from the carburetor inlet fitting.
2. Immerse the hose in a specially prepared transparent bottle. By actively using the pumping lever manually, we notice how strong and dense the fuel is supplied. Air impurities should not be visually noticeable.

Delayed jet output is not a sign of a breakdown, especially if the car has been parked for a long time. As a rule, diaphragms eight and nine are the main cause of malfunction.

Where are the fuses and relays located?

Depending on the generation of the car, the fuse blocks have differences, and, consequently, different installation locations.

Location of fuse and relay blocks on Lada Kalina 1

The first generation Kalinas were equipped with several fuse blocks at once. Their location has several places and they are all in the cabin:

1. The main unit is located under the panel, to the left of the steering column.
2. Another block was mounted under the cigarette lighter, next to the gearshift lever.
3. Another mounting block is located under the dashboard, inside the central tunnel.

Where are the mounting blocks located in Lada Kalina 2

The second generation Lada Kalina has two fuse blocks. The main one is located inside the cabin, and in some trim levels it is also installed under the hood.

1. One is located in the cabin, to the left of the steering column, under the cover.
2. The additional fuse box is located in the engine compartment, to the right of the battery.

It is worth considering the location of the mounting block to avoid mistakes in diagnosing the car.

List of contact relays

Removing the instrument panel assembly with heater Lada Kalina

If we open the main fuse box of Kalina 2, we will see a set of electrical relay housings. There are no other blocks containing relays in the car. We list the elements used in the “Lux” package (21927/21947):

• K1: radiator fan relay;
• K2: relay switching on door locks;
• K3: additional starter relay;
• K4: additional relay (switches current 50A);
• K6: wiper relay;
• K7: relay that turns on the high beam;
• K8: signal relay;
• K9: relay that turns on the low beam;
• K10: rear window heater relay;
• K11: main ignition relay;
• K12: relay turning on the fuel pump;
• K13: additional relay;
• K14: radiator fan relay 3;
• K15: windshield heater relay 1;
• K16: windshield heater relay 2;
• K17: relay that turns on the air conditioning compressor.

You can compare the layout of elements in “Lux” and in “Norm/Standard”:

This is how the relays are located in different configurations, 21927 and 21925

Let's consider the data relevant for the “Normal/Standard” configurations:

• K1-K12: as above;
• K13: radiator fan relay 3;
• K14: windshield heater relay 1;
• K15: windshield heater relay 2;
• K16: air conditioning compressor relay.

The last list is also relevant for Kalina Cross Norma. And in more expensive trim levels of the crossover, the “Lux” scheme will probably be used.

Correct selection and replacement of fuses on Kalina

The fuse in a car is a plastic product with two contacts, inside of which there is a fuse link.

Different fuses are designed for different current values ​​and if this parameter is exceeded, the insert burns out. It is very important to install the same one in place of the required fuse and not make a mistake.

For example, if a 15 Ampere fuse is installed on the cigarette lighter, then it is no longer possible to install a 60 Ampere or 5 Ampere insert.

The fact is that with a high operating current, the device can burn out or melt the wiring in the event of a malfunction. And with a high current of 15 Amps, a 5 Ampere fuse may blow immediately after turning on the device, since it is not designed for such work.

Changing the mesh with your own hands

So, the mesh located in the fuel pump is forced to constantly come into contact with dust and dirt, because the pump itself is located between the seats, and dust constantly settles on its body.

That is why experienced motorists are not lazy to wipe the pump body with a damp cloth from time to time to avoid untimely clogging of the system.

Motorists advise carrying out such work every 45,000 - 50,000 km. mileage, this is exactly the time during which the Kalina mesh wears out. Of course, this work is classified as dusty, but, in principle, it is not as difficult as it seems, it can be done alone, in half an hour - an hour.

How to select and replace a relay on Kalina

A relay in a car is used to remotely control consumers that require high currents.

For example, to activate the starter, the ignition switch contacts and its wiring will not be enough. Therefore, the lock serves only as a control device, and the relay closes the power contacts and the retractor relay circuit.

In cars of both generations, the most common 4 and 5-pin relays are used. However, two types of sizes are used here; this should be taken into account when selecting. It is better to look at the characteristics of the relay on the body and buy exactly the same one or show the required relay to an auto parts dealer. Automotive relays can vary in current strength, number and location of contacts.

To replace faulty relays and fuses on the Lada Kalina, use a special “pliers” tool, which is installed in the lower right corner. The larger ones are for relays, and the smaller ones are for fuses.

If, after replacing the fuse, it has blown again, you should not try to change it again; most likely there is a short circuit in the circuit and the car must be sent for more thorough diagnostics.

The fuel pump does not pump: causes and diagnostics

VAZ 2110 fuel pump pinout

Let's start with the fact that if the gas tank is full, the battery is charged, the spark plugs are dry and there is a spark, the starter turns the engine normally, but the engine does not seize, then you should pay attention to the gas pump. A common problem is that there is no power to the fuel pump after the ignition is turned on.

In a similar way, the malfunction manifests itself in motion, when the power to the fuel pump is lost and the engine suddenly stalls.

An equally important point is how much the fuel pump pumps. In other words, the pump may hum and buzz (power is being supplied), but not create the required pressure in the fuel line. The pressure in the fuel system with a working fuel pump must be more than 3 bar (which depends on the specific car model). The indicated pressure is accumulated in the fuel rail and has an indicator of 300 kPa and above.

To check, you need to measure the pressure in the fuel rail with a pressure gauge, taking into account the indicators that are the norm for a specific car model. Using the example of injection VAZs, the pressure when the ignition is turned on is 3 atmospheres, at idle the figure is 2.5 atmospheres, when you press the gas 2.5-3 atmospheres. This method will help you accurately determine:

• malfunction of the fuel pressure regulator in the rail;
• breakdown of the fuel pump or a noticeable decrease in its performance due to wear;
• severe contamination of filters (fuel filter and/or fuel pump mesh);

In the second case, when you press the gas, the pressure does not increase; in the latter case, the pressure gauge needle rises, but very slowly or jerkily.

A decrease in pressure below the norm will lead to the fact that the engine may not start or start with difficulty, stall, jerk, operate unstably and with failures. If this happens due to the fault of the pump and not the fuel filter, then there is a high probability that the coarse filter screen of the fuel pump is clogged. In this case, there is no need to change the fuel pump itself, since it will be enough to replace or even clean the mesh.

If you suspect that there is no voltage to the fuel pump, there is a quick way to check. It is enough to turn the ignition key and listen, as when you turn the key you should hear a slight hum from the fuel pump. If such a buzzing noise is not heard, it means there is no power to the fuel pump, there are problems with the wiring, etc.

Also in the general list of possible reasons why the fuel pump does not pump, the following are noted:

• failure of the fuel pump fuse;
• fuel pump relay failure;
• problems with the ground of the fuel pump;
• malfunction of the electric motor of the fuel pump;
• oxidation or damage to fuel pump contacts and terminals;
• the fuel pump itself is faulty;

Wiring to the fuel pump

On most cars, the wiring to the fuel pump consists of three wires: “plus”, “minus”, and also a wire for indicating the amount of fuel in the gas tank. If the fuel pump does not pump, then the cause may be a lack of power.

To check the power to the fuel pump, just take a 12-volt light bulb and supply it with power from the external connector of the fuel pump. After turning the ignition, the control lamp should light up. If this does not happen, then the problem is in the external circuits. If the lamp comes on, it will indicate the need to check the internal contacts of the fuel pump.

Fuse and relay diagram in Kalina 1

As mentioned earlier, in the first generation Lada Kalina there are three fuse and relay blocks. Therefore, each should be considered separately.

Main unit

To understand which fuses are installed in the main unit and what they are responsible for, you should read the table:

The last four fuses are backup and are necessary to replace blown ones.

To find out which relay is responsible for what in Lada Kalina 1, just study the following table:

Fuse box under the cigarette lighter

There are only three inserts installed here. The purpose of the fuses is to protect the circuits of the engine injection system.

Fuse and relay box under console

Closes the power parts of the engine injection system. On the second generation of the car, almost all relays and fuses from here will go to the main mounting block.

Similar symptoms not related to the fuel pump

The symptoms that appear due to a lack of fuel in the supply line are quite typical and are very similar to problems with other systems. How to eliminate possible problems using the elimination method:

1. Unscrew and inspect the spark plug skirts. When there is not enough fuel, the electrodes remain clean or become covered with a white coating. This is further evidence of a malfunction in the power system.
2. Replace spark plugs. If they wear out, they create a similar effect - failures, difficult starting, and a drop in engine power.
3. Check the functionality of the throttle position sensor (TPS) and idle air control.
4. Measure the compression in all engine cylinders. Due to excessive wear, the naturally aspirated engine is unable to create the required pressure and vacuum; the mixture burns poorly, which is why identical symptoms occur.

When troubleshooting, take into account one important factor - the service life of the fuel pump, which is at least 100 thousand kilometers. The longer the operating period of the unit, the lower the fuel pressure it creates at the outlet. The reason is wear of the membrane and other internal parts. If the pump has served 150 thousand km or more, you should think about purchasing and installing a new spare part.

The Lada-Kalina submersible fuel pump, as in other cars, is necessary to supply gasoline to the combustion chamber of the internal combustion engine. The pump is activated immediately when the ignition is turned on and maintains operating pressure until the car is turned off or the fuel runs out. The fuel pump is part of a module that includes a fuel pressure regulator, which changes the supply parameters when the driver operates the accelerator pedal. The module also contains a sensor that sends data to the dashboard, to the fuel level indicator. In addition, the design of the fuel filter includes a fine-mesh mesh for coarse fuel cleaning.

Table of fuses and relays in Lada Kalina 2

Lada Kalina 2 is significantly different from its predecessor and has a slightly different block with a different arrangement of fuses.

Main unit in the cabin

To understand what the relays and fuses on Kalina 2 are responsible for, study the table:

Why do fuses blow and what are the symptoms?

Fuses never blow without a reason, and the Lada Kalina is no exception. Fuse links protect circuits from the following faults:

The task of the fuse is to save the electrical circuit: wiring, consumers and to prevent a fire caused by melting of wires or other parts of the electrical circuit.

A short circuit is one of the reasons for the melting of the insert, which most often occurs due to damage to the wires, a short circuit of the “plus” to body ground, or during an accident, as a result of which the harness or a separate wire was cut by a part of the body.

Overloads can be caused by the simultaneous operation of many consumers or when using low-quality compressors to inflate tires, powered from the cigarette lighter.

There is another reason, which occurs extremely rarely - the use of Chinese fuse-links, the operating current of which is slightly lower than that provided by the electrical circuit. Despite the fact that 15A may be indicated on the insert body, in fact, this figure may be lowered to 10.

The symptom of a blown fuse is complete failure of the consumer. For example, if the cigarette lighter does not work, then in 90% of cases, a blown fuse is to blame. To make sure of this, just open the lid, take out the fuse-link, guided by the table, and check its integrity. If this cannot be done visually, you can use a multimeter in dial mode.

A serviceable fuse should ring, but a blown fuse will show an open circuit on the device. If replacing the insert does not help, you will have to diagnose the fuse box or look for the problem elsewhere.

It is prohibited to use wire to repair the fuse! This may cause the wiring in the vehicle to catch fire.

About the reasons for the failure of the fuel supply system

As noted, in the Lada Kalina model the fuel pump is equipped with an electric drive. This provides a number of specific and important benefits. Here the priority is simplicity in design and reliability, allowing the device to have an impressive service life. We also note the high safety when the fuel supply system stops functioning when the engine is stopped. In order for the pump to “live for a long time”, it requires high-quality gasoline, which also serves as a coolant for the device.

So, more about the main reasons:

1. Fuel with quality standards that do not meet standards. This leads to gradual clogging of the filter and incorrect operation of the gasoline supply unit.
2. Open circuit in the electrical power supply circuit of the pump. Here the culprit may be not only the fuel pump fuse, which, by the way, should be checked as a priority, but also the fuel pump relay. Also among the reasons may be oxidized contacts of the pump power supply or broken supply wires, which happens much less frequently.

In any case, if the pump does not work, then a thorough diagnosis of the entire fuel supply circuit will be required; you must check the pump fuse, as well as the fuel pump relay.
