Gasoline pump Lada Largus (removal and installation)

We disassemble the module in order to change the filter

The main thing to keep in mind: first disconnect the brown connector.
Then remove the level sensor by unfastening the clamp with a screwdriver. Disassembling the pump module

Similar clamps also hold the top cover. Having removed it, disconnect the snow-white connector (see photo). How to remove the lower part of the module is discussed in the previous chapter. But you will have to tinker with the pipes: when putting them on or removing them, the fittings need to be held above the steam.

The most difficult operation

No one was able to achieve results right away.

What is the best way to deal with a test tube?

On the Lada Largus, the fuel filter is a test tube containing paper. This tube is not sold separately, and it is not allowed to change it. But it can be cut to remove the filter element one hundred percent.

Fuel filter housing

At the last step, both halves are glued together, and drying is done under pressure (on ties).

So, we have an “empty” filter housing that is installed in the space. After assembling the module, it can be used, but there is a condition: after 1000-2000 km the module will have to be changed. Follow our advice if the engine has “ran” 150-160 thousand and you no longer feel sorry for it.

What should you not create?

It would seem that you can drive for a long time with a cleaned tube, you just need to insert a new filter into the fuel line. This is usually done by taking a filter from Renault Logan (phase 1).

Fitting the filter into the line under the hood

What comes out is this:

If the test tube is empty and an “external” filter is added, the motor starts and stalls after 2-3 seconds;
If the test tube has not been cleaned, adding a new filter is useless: the overload on the pump increases, and that’s all.

Let the reader draw his own conclusions.

Another variant

Below is a test tube that looks almost the same as the unique fuel filter of the Lada Largus.

Gasoline pump Lada Largus (removal and installation)

VAZ 2110 fuel pump pinout
If engine power drops, increased noise occurs, or noise is periodically heard when the fuel pump is operating, then most likely the fuel pump has failed. Pre-check the pressure in the fuel supply system. If the pressure in the system is less than 3 kgf/cmg, this may be caused by a malfunction of the electric pump, fuel pressure regulator, or clogged filter elements. In some cases, the fuel pump module can be repaired, but to do this it must also be removed from the vehicle. If all indirect signs indicate that the pump is faulty, then it must be removed and replaced. You will find information on how to do this in this article.

The filter element that cleans the fuel entering the injector or carburetor is considered important in this system. The interesting thing is that this small unit, when used correctly, can increase the service life of the motor by up to 30%. If you do not promptly replace the fuel filter when it is dirty, rapid wear of the injection system is possible, which will lead to disruption of fuel injection and a decrease in engine power.

Changing the fuel filter on a Lada Largus with your own hands

Electrical diagram for connecting the fuel pump VAZ 2110

The fine fuel filter on Largus station wagons and vans is built into the fuel pump module. According to the regulations, this filter must be changed together with the module, and the period between replacements is 160 thousand km. The Renault company, unlike VAZ, specifies an interval of 120 thousand, but the essence will be the same - replacing the fuel filter on the Lada Largus and Logan is carried out only with a pump. We will look at what can be done to get a completely usable, but still temporary solution. At the same time, it will be indicated how to replace the mesh filter.

If anyone doubts the presence of a “paper” filter, you can look at it from the inside. Here's a video.

Frequency of replacing the fuel filter

According to official statements from the manufacturer, the fuel module and, accordingly, the filters contained in it are designed for the entire service life of the vehicle. Its replacement is not provided, so there are no official recommendations on the frequency of installation of new consumables.

Operating experience of the Lada Largus showed car owners the need to replace fuel filters, both fine and coarse. According to the observations of drivers, the mesh becomes clogged when the mileage approaches 30-50 thousand km. The fine filter lasts a little longer. Its replacement is usually necessary after a mileage of 60-100 thousand km.

The following symptoms indicate the need to change the fuel filter:

difficulty starting the engine;
jerking while moving;
During intense acceleration, the engine stalls;
the engine does not work well under load;
deterioration in dynamics;
Extraneous sounds appeared when the fuel pump was operating.

Changing the fuel filter on the Lada Largus with your own hands

Replacing the fuel filter on a Lada Largus is not so difficult if you know where it is located and how to carry out the repair correctly. It is worth noting that even an amateur car repairman can carry out the replacement procedure, since the whole process is extremely simple. The event does not require any special preparation, except for taking the following measures:

Place the car in a reasonably spacious and level place, securing it securely (handbrake, wheel stands, etc.);
prepare a basic car repair kit: a set of keys, a pair of screwdrivers, rags and gloves;
purchase a fuel pump assembly or a fuel pump “mesh” separately in advance (for example, a similar part from Renault Logan will do).

The replacement procedure itself takes no more than half an hour, of course, if you are not going to completely disassemble the fuel pump and try to clean the filter using “old-fashioned” methods or replace it with a homemade one. Moreover, it is undesirable to do this only because by incorrectly cleaning or assembling the fuel pump, you can provoke more serious damage to the fuel system of your Lada Largus. Is it worth it? Most likely no.

So, the algorithm for replacing the fuel filter is as follows:

Remove the rear sofa cushion and lift the plastic hatch underneath. For ease of work, you may need to move the carpeting to the side.
Having first disconnected the battery, bend the tab on the fuel pump connector and disconnect it.
Next, you need to connect the battery and start the engine. The running engine should run for a few seconds and then stall. After this, de-energize the system again by disconnecting the battery terminals.
Disconnect the fuel pipe and unscrew the fuel pump retaining ring counterclockwise. Using a mounting spatula will help make this step easier.
After completing the previous steps, the fuel pump module can be removed. If necessary, replace the mesh filter or the entire fuel pump. After replacement, it is necessary to reassemble the entire structure in reverse order.

Important! It is not advisable to disassemble the fuel pump to replace the filter. This practice may negatively affect the condition of the entire fuel system in the future. It’s better not to skimp and replace the entire fuel pump

It’s better not to skimp and replace the entire fuel pump.

As you can see, replacing the Lada Largus fuel filter is quite simple if you know its design features and location in the car. We hope the material presented above was useful to you. Good luck on the roads and in repairs!

Gearbox malfunctions and methods for eliminating them

Any mechanism has a tensile strength, especially if it operates under variable loads. It is necessary to take into account the driver's driving style, which significantly affects the durability of the part. Summarizing the accumulated experience and analysis of breakdowns that occur during the operation of the car, gearbox faults can be grouped into several main groups: noise in the gearbox, difficulty engaging the gear and spontaneous shutdown of the transmission.

Noise and difficulty shifting gears

The main causes of noise in the gearbox include:

low oil level;
water entering the system;
wear of bearings or gears.

To fix the problem, you should add or replace the oil in the gearbox, replace the bearings and gears with new ones.

Difficulty shifting gears can be caused by the following factors:

faulty gearbox control rod;
loosening of fastenings;
deformation of control drive parts;
wear of synchronization rings;
incomplete disengagement of the clutch.

Spontaneous transmission shutdown

The reasons for spontaneous shutdown of the gearbox are usually:

gear wear;
damage occurs on the rubber supports of the box;
wear of the synchronizer rings.

These faults can only be corrected by replacing them with new parts. Do-it-yourself transmission repair requires high qualifications and a set of special tools. Only a competent specialist can remove and disassemble this part correctly.

If the gearbox malfunctions, it is better to contact a service station, where they will not only repair the unit, but will also give you a guarantee that you can use in the event of a subsequent gearbox breakdown.

Changing the fuel filter on a Lada Largus with your own hands

If anyone doubts the presence of a “paper” filter, you can look at it from the inside. Here's a video.

Operating principle

In the Lada Largus model, the design of the filter component has an unusual solution, so replacing the fuel filter can cause a number of minor difficulties. The unit consists of two components that ensure cleaning of the fuel entering the system. They are located in the pump itself and represent a single module that can be replaced entirely. The manufacturer has included an enviable resource in the filter component, which, if the owner complies with regulatory requirements, can reach 160 thousand km.

If there is a need to replace the filter, you will need to dismantle the fuel pump, and this procedure is quite labor-intensive and painstaking. In such a situation, a reasonable action would be to replace the fuel filter, that is, the entire module, consisting of two components. Frequent disassembly procedures of this unit, for example, to replace one of the components, are extremely undesirable for the fuel pump and its associated infrastructure.

161Akb-Pomosh › Blog › Replacing the fuel pump Largus Van

Initially, the car did not keep idle speed when “cold”; the only thing that helped was to keep the engine at low speed until it warmed up. Since the Largus was being painted, this did not bother me much, until it stopped starting altogether - the starter turned, but to no avail. In this case, I wouldn’t have to rack my brains and go for diagnostics, but I couldn’t drive under my own power, and I didn’t really want to drag it on a cable. As a result, after studying the mat. parts on the Internet)) was done: 1. All relays and fuses have been checked.2. The throttle was cleaned and the small o-ring was replaced (it already had a square shape and microcracks. I didn’t change the big one, it looked in good condition).3. Cleaned the DPKV, measured the resistance - 243. It seems to be normal for the K4M engine. It was very difficult to get it; personally, it took me an hour of time and a little swearing)).4

I paid attention to the immobilizer operation indicator - it stopped blinking if you inserted the key into the ignition. An experienced technician would say. What about the fuel pump? Can I check it? But I didn’t want to believe that at 104,000 km it died - I didn’t want to, because before that on other cars of different brands I ran 150 t.km. In short, after listening to whether the pump worked before starting the engine, I decided to remove the fuel module from the gas tank

I won’t post photos of the whole process, there’s a lot on the internet, but I couldn’t find how to get it out of the van. Maybe it will be useful to someone.1. Remove the negative terminal from the battery.2. Remove the rubber carpet in the cargo compartment, if there is one.3. The floor of the cargo compartment is divided into three parts; unscrew the part that is closer to the right cargo door. You will need a Torx key, I don’t remember how much, take a set because you will need 2 sizes.4. Part of the floor goes under the plastic bulkhead - so as not to unscrew it, I simply lifted it up and secured it to the ceiling with a rope.

5. I had a LOT of dust in the well of the fuel module (3 centimeters), so it is advisable to vacuum it or blow it with air so that it does not get into the tank. I took a photo of the fuel pipe that fits onto the Module; the inside is terribly dirty.

6. Then everything is standard - I took out the module, pulled out the fuel pump (I threw plus and minus on the battery and fuel pump terminals - it doesn’t work, so it needs to be changed). I bought a pump from a VAZ 2110 in a nearby store, along with a cleaning mesh - 550 rubles. I read that there was still a need to change some kind of module for fine cleaning - I didn’t bother, in the future there are plans to convert the car to gas.

Removal and repair of the Lada Largus electric fuel pump module

We remove the fuel pump module if the electric fuel pump fails completely or partially, the fuel pump filter is clogged, or the fuel gauge sensor is faulty.

Preparation for module removal largely depends on the car model.

To remove the module, we prepare the car for work.

It is advisable to remove the module so that the amount of fuel in the tank is less than half the tank.

1. If the car is a station wagon, then we tilt the rear row of seats forward for a five-seater configuration and the middle row for a seven-seater configuration.

2. Disconnect and lift the floor covering

When to change the fuel pump

The reason for replacing the fuel pump, in addition to its complete failure, is usually a changed behavior of the car.

The most characteristic signs of pump failure: - partial loss of power; — inadequate reaction to “gas”; — unstable engine operation at minimum idle speed; — change in the tone of the engine; — noise in the fuel tank; - Uncertain engine start.

In all these cases, as a rule, mechanical wear of the electric fuel pump parts or burning of its contacts is to blame. Sometimes the fuel inlet filter is simply dirty. It can be washed, or better yet, buy a new one and replace it. To carry out this operation, it is necessary to remove the fuel module.

Removal

Place the vehicle in the workplace and apply the parking brake.

Removing the fuel module

We will perform all the steps as if we were trying to replace a fuel pump:

We tilt the sofa cushion and remove it. We lift the plastic hatch and move the carpet forward. Remove the round cover from the hole;

Getting rid of unnecessary details

Understanding electricity

First - the pipe, then - the clamp

By removing the module assembly, you can replace the mesh filter. Be careful not to lose the O-ring installed between the module and the tank.

Replacing the filter mesh

On the Lada Largus, the coarse fuel filter is a removable mesh in front of the pump. Replacing it will be simple:

We snap off the glass latches (3 pcs.);

Let's start disassembling the module

The very first element in the fuel tract

Installation of all modules and components is carried out in the reverse order. If the mesh is not badly damaged, it can only be washed and dried. Car chemicals based on xylene or ethoxylated alcohols will help.

Design of the fuel filter flask in the pump

What is outlined in the figure is the fine filter. Through mesh 2, fuel enters the pump, then it enters container 3. This container is connected to the ramp through the upper fitting and pipe. Connection 1 is also an important element, since it is connected to the return valve.

Fuel module disassembled

The return flow valve is built into the lower glass, and it allows you to relieve excess pressure.

By the appearance of part 3, you can always assess the degree of filter clogging. It's a pity that the container is non-separable. Unfortunately, it is pointless to look for the article number for part 3: the fuel filter on the Lada Largus is replaced as an assembly with the pump.

What is the purpose of the filter?

The uninterrupted operation of 8-valve and 16-valve motors is ensured provided that the fuel supply system operates correctly. Thus, longer preservation of the components of the cylinder-piston group is achieved. The filter is designed to be “responsible” for ensuring the cleanliness of the fuel entering the engine chambers.

This implies the presence of the following functions among the tasks of this element:

prevent the penetration of solid particles of various origins into the engine along with fuel, which can cause rapid wear, not only damage to the walls of the liners, but also cause irreparable damage to the engine;
take care of maximizing the service life of the unit.

When to change

You will not be able to know if the fuel filter is dirty unless you regularly check its integrity and condition. Due to the specific design, the fuel cell on Largus is endowed with a “heroic resource”. As AvtoVAZ says, fuel filters together with the fuel pump are designed for the entire period of operation of the car, that is, about 160 thousand kilometers. But is this true? Based on practical experience, no.

Considering the average statistics, we can highlight the following:

a mesh filter in the nozzle of the injection system, which passes fuel through itself after primary and fine cleaning, can last no more than 30-45 thousand kilometers;
The main fuel filter has a service life of 80-120 thousand kilometers.

Experienced car repairmen advise every Largus owner to dismantle the entire fuel pump module and check the level of filter contamination every 20 thousand kilometers. The check is also carried out if:

slight loss of traction;
problems with the fuel system;
reduction or increase in fuel consumption.

The main difference between the fact that it is the fuel filter element that is dirty is the gradual appearance of the symptoms described above.

DEVICE AND PRINCIPLE OF OPERATION

An engine, similar to a living organism, is able to “live” for a long time only on the condition that it consumes pure raw materials for its functioning. In terms of the fuel system, the fuel filter is responsible for organizing the purity of the gasoline entering the car engine. This part, simple in structure, performs functions of great importance for any transport. In particular, this Lada Largus unit allows:

prevent large fractions from entering the injector and cylinders along with gasoline;
filter out a considerable amount of small fractions also present in the fuel;
extend the service life of both the engine and the entire fuel system.

Removing the fuel module

Replacing the filter mesh

On the Lada Largus, the coarse fuel filter is a removable mesh in front of the pump. Replacing it will be simple:

We snap off the glass latches (3 pcs.);

Let's start disassembling the module

The very first element in the fuel tract

Lada Largus fuel pump does not work - the main reasons

1. The first thing to check is the fuel pump itself.

To do this, check whether voltage is coming to the fuel pump block. This can be done simply using a regular lamp or multimeter. If the light comes on, then voltage is going to the block, then you will have to disassemble the fuel station and look at the pump.

Fuel pump fuse Lada Largus

This is another common reason why the Lada Largus fuel pump does not work. The Largas fuel pump fuse is located in the mounting block under the hood.

We open the mounting block and find fuse F3 at 25A. This is exactly what it should be like from the factory. We check the fuse, if it is burned out, replace it with a new one.

Fuel pump relay Lada Largus

A faulty fuel pump relay on the Lada Largus is also a common failure in domestic station wagons.

You can also find the Lada Largus fuel pump relay in the mounting block under the hood marked K4 in the diagram.

Connector Lada Largus fuel pump

Another common breakdown is the Lada Largus fuel pump connector. This is due to poor contacts, which over time can oxidize, heat up and melt the pad. If measures are not taken, the contact will disappear completely, completely cutting off power to the fuel pump. The way out of the situation is to replace the block, which has the article number:

4631148764668 Connector for fuel pump module “LADA Largus”

And if the contacts of the fuel pump module are burnt, you will also have to buy the upper part of the pumping station:

Replacing the fuel pump on Largus

Traditionally, two fuel filters are installed on Lada cars to purify gasoline. One of them is called a coarse filter (mesh) and is located in the fuel pump, and the other fine filter is in the form of a separate module (replaced after 10-20 thousand km), which is attached to the bottom of the car near the gas tank. Let's look at how to replace the Lada Largus fuel filter.

If you open the “do-it-yourself repair manual for Lada Largus”, then in the “power system” section you will not find the usual instructions for replacing the fuel filter. The fact is that both filters (coarse and fine) are built into the fuel module (gasoline pump). If it is not difficult to clean or change the fuel pump mesh, then replacing the Lada Largus fine fuel filter will not work; it is only replaced as an assembly with the fuel pump after 120 thousand km. mileage

fine filter (JS ASAKASHI FS22001, JAPANPARTS FC-130S, PATRON PF3924)

To remove the Lada Largus fuel pump, you will need to disconnect the negative terminal of the battery, and then remove the floor covering in the rear seat area by unscrewing several screws. Remove the plastic cover by prying it off with a flat-head screwdriver. Disconnect the connectors and fuel line from the fuel module and remove it by unscrewing it with a special key.

By disconnecting the lower part of the fuel pump, you can gain access to the coarse mesh. It is replaced with a new one, or cleaned and installed in the reverse order.

It is not possible to replace the fine fuel filter; you can only cut its housing, first removing the fuel pump:

Let us remind you that the Lada Largus has other design features, for example, this model does not have a cabin filter.

The fine fuel filter (housing), the coarse filter (mesh), the fuel pump, and the fuel level sensor are located in the fuel module complex, which is located in the fuel tank.

Note: According to the regulations, replacement of individual parts of the fuel module is not provided, and in the event of failure of any of its components, the module is replaced as an assembly. However, in an emergency, to replace the fuel pump, clean the fuel filter, or replace the fuel level sensor, the module can be disassembled.

To disassemble the fuel module and replace parts, remove it from the vehicle. (see here)

Disconnect the fuel level sensor wire block from the cover

Remove the fuel level sensor by sliding it in the direction of the arrow

Fuel level sensor 1 – resistor; 2 – slider; 3 – sensor wire block; 4 – float; 5 – float lever

Using a screwdriver, press out the three plastic clips...

...and remove the glass from the fuel module body. Here is a fine fuel filter (housing) and a coarse mesh filter

Fuel pump Lada Largus 16 valves article number and 8 valves

The Lada Largus fuel pump for a 16-valve engine comes under the article number 172024388R.

8-valve engines and 16 valves have the same fuel pump and are no different. It would be more correct to say that this is not the fuel pump itself, but the fuel station assembly. The manufacturer intends to completely replace the entire fuel station without any repairs.

However, this does not mean that a new electric element of the fuel pump cannot be purchased and replaced. Here are some items for ordering the Lada Largus fuel pump itself:

BM FP0007 Kraft KT800080 Gallant GL.FP.1.2

We disassemble the module in order to replace the filter

The main thing to remember: first disconnect the brown connector. Then remove the level sensor by unfastening the clamp with a screwdriver.

Disassembling the pump module

The most difficult operation

No one was able to achieve results right away.

What is the best way to deal with the flask?

On the Lada Largus, the fuel filter is a flask containing paper. This flask is not sold separately and cannot be replaced. But it can be cut to remove the filter element completely.

Fuel filter housing

At the last step, both halves are glued together, and drying is done under pressure (on ties).

What not to do!

It would seem that you can drive for a long time with a cleaned bulb, you just need to insert a new filter into the fuel line. This is usually done by taking a filter from Renault Logan (phase 1).

Fitting the filter into the line under the hood

It turns out this:

If the flask is empty and an “external” filter is added, the engine starts and stalls after 2-3 seconds;
If the flask has not been cleaned, adding a new filter is useless: the load on the pump increases, and that’s all.

Let the reader draw his own conclusions.

Alternative option

Below is a flask that looks almost the same as the original Lada Largus fuel filter.

JS Asakashi brand components

This flask can be installed instead of the standard one. You just need to shorten the fastening elements (tubes) by about 20 mm. We were talking about filters for Nissan cars:

Connection and installation of car alarm pandora dx 50 on lada largus

The Lada Largus does not have a can tire (there is only a lin tire). Therefore, all connections are made analogue.

You can connect the ground to the standard place behind the instrument panel.

masses

Connect the parking brake switch to the black connector of the instrument panel.

Handbrake

You may have to insert a diode into the break in the handbrake wire and make the connection according to the figure below.

Connect the tachometer to the black connector of the instrument panel.

tachometer

Do not forget to select the method of monitoring engine operation in the Alarm Studio program - an analog tachometer. Otherwise, if you leave the default value - digital tachometer, then there will be no auto start, since the alarm will not be able to determine whether the engine is running or not.

Setting up the Alarm Studio program

It is also possible to connect to the generator wire for engine control. In this case, the car alarm should be connected to the pin 13 wire of the black connector on the instrument panel - orange wire. In the Alarm Studio settings, you should allow control of engine operation via the generator and assign one of the additional alarm inputs as a “charging lamp”.

Setting up the Alarm Studio program

In the harness of the gray connector of the instrument panel, connect the limit switches of all doors

Door switch

You may have to use decoupling diodes to connect to the limit switch. In this case, we use the following connection diagram.

You can also connect to the door switches on the BCM, located to the left of the steering column.

Signals from the door and trunk switches are located on the wires in pins 30 and 40 of the green insert of the black 40-pin BCM connector.

Door and trunk limit switches

It may also be that the car is missing limit switches for all passenger doors (or only the rear doors). Then it is necessary to install additional sensors. It is possible to install both an original limit switch and a non-original one.

Opening and closing the central lock is carried out by connecting to a button on the central panel. Negative impulse control.

Locking the lock unlocking the lock

You can also connect to the central locking control wires in pins 17 (closing) and 8 (opening) in the brown insert of the black 40-pin BCM connector.

The warning light is connected to the hazard warning button on the center panel, brown wire. Management of potential negative potential.

Emergency crew

Steering control can be done by connecting to the wires on the BCM.

Turns

It is convenient to connect to the power wires for autostart behind the dashboard.

Electric fuel pump circuits can be used as a blocking mechanism. The fuel pump can be blocked at the fuel pump relay under the hood (white wire) or in the driver's threshold.

Gasoline pump

After all the connections have been made, it is necessary to record the idle speed in the Pandora DX-50 memory. To do this, enter the programming mode at level 1-3 and perform the steps described below.

Replacing the fuel pump Lada Largus (VAZ Largus)

If engine power decreases, increased noise occurs, or noise is periodically heard when the fuel pump is operating, then most likely the fuel pump has failed. Pre-check the pressure in the fuel supply system. If the pressure in the system is less than 3 kgf/cmg, this may be caused by a malfunction of the electric pump, fuel pressure regulator, or clogged filter elements. In some cases, the fuel pump module can be repaired, but to do this it must also be removed from the vehicle. If all indirect signs indicate that the pump is faulty, then it must be removed and replaced. You will find information on how to do this in this article.
