Poor starting on a hot VAZ 2114

Sometimes car owners are faced with a situation where the VAZ 2114 has difficulty starting when hot. This means that a car with an already warmed-up engine cannot start. This problem is considered one of the typical ones for the VAZ-2114 and its predecessor, the VAZ 2109. To find out what exactly is the reason, you should examine all the vulnerable spots in the car.

2114 does not start when hot

Why is the VAZ 2114 8-valve injector difficult to start?

For some reason, it seems that many drivers of this model will be interested in the question of why the VAZ 2114 8-valve injector does not start well.
Finding the cause of this phenomenon is not as easy as it might seem at first. This is due to certain difficulties in troubleshooting in this model, since injection systems differ from carburetor systems. The algorithm for identifying possible problems will be built differently, adapting to the design features of the machine. Why is the VAZ 2114 8-valve injector difficult to start?

, we will try to consider in this work. In a short article it is impossible to consider absolutely all possible problems; there are some that can only be identified with the help of diagnostic equipment. But, nevertheless, we will try to analyze as many such situations as possible in order to help all VAZ 2114 owners decide what to do in such a situation.

Why might the engine be difficult to start?

You can look for the culprit in such a situation in several directions. Among them, the most important problems are:

Malfunctions in the ignition of a VAZ 2114 car
There is no pressure in the fuel rail of the 8-cl VAZ engine
Air leak into the VAZ intake manifold
Timing belt marks are misaligned

Engine diagnostics using spark plugs

Let's look at the first option, why the VAZ 2114 doesn't start well. To do this, unscrew the candles and look at their color. If there is black dry carbon on the candles, we can say that the engine has been running for a long time on a rich mixture, which covers the candles with black carbon.

Why does black carbon appear on the spark plugs of an injection car:

Malfunction of the mass air flow sensor
The first oxygen sensor has failed
Fuel pressure regulator is faulty
Malfunction of fuel injectors

White carbon deposits on the spark plugs of an injection car appear due to a lean mixture, the reasons for the appearance:

Everything is the same as with black soot
Malfunction of the fuel pump or clogged fuel filter (check the mesh and fine filter)
Air leaks through the air flow sensor pipe, the place where the regulator is attached to the XX joints of the manifold.

Checking the spark plug spark

The lack of a spark on one 8-cl spark plug of a VAZ engine will not affect the engine starting, it will be noticeable when idling, tripping and jumping revs. But if the ignition module of the VAZ 2114 is faulty, then the spark disappears in two cylinders 1-4 or 2-3. To check the spark plug spark, take out the fuel pump fuse, unscrew one spark plug or take a spare one, remove the high-voltage wires one by one, put them on the spark plug, then put the whole thing on ground (in this case, the valve cover) and ask a friend to crank the engine with the starter, so we check each spark plug. If there is no spark on one spark plug, most likely there is a defect in the explosive wires; if there is a spark in two or all spark plugs, it is highly likely that the problem is in the ignition module or the wiring to it.

The timing marks on the VAZ are not set correctly

Another reason why the VAZ 2114 does not start may be a mismatch of the timing marks. The reason for the mismatch of the marks may be weak timing belt tension, cut teeth, or the crooked hands of a mechanic at a service station.

A discrepancy of more than two teeth will noticeably affect the operation of the engine of the fourteenth. With a slight deviation, the engine starts up a little worse, does not hold idle, and stalls when switching to neutral gear. If the deviation exceeds 4-5 teeth, the sound of the engine changes, air escaping under pressure through the valves that are not opened in time becomes audible, thrust noticeably disappears, and starting the engine is extremely problematic.

To check, we need a “10” key; use it to unscrew the three bolts securing the timing case.
Next, put the car in 5th gear and push it until the mark on the camshaft pulley and the rear cover match, you can also turn the pulley with the key to “17”
We remove the protective plug from the clutch housing and see if the mark on the flywheel matches the mark; if not, then you need to loosen the tension roller and align the belt according to the marks.

The VAZ 2114 car does not start when hot, but when driving everything is fine

The VAZ 2114 car does not start when hot, but when driving everything is fine. And so you can start it with a push. Who knows where to dig. The spark plugs were also replaced with wires. I have a video on my page, check it out.

26 comments on “The VAZ 2114 car does not start when hot, but when driving everything is fine”

Ignition module! Try removing it while it's hot and cooling it down.

I also had the same bullshit, the timing marks were knocked off

Check the crankshaft sensor

Possibly the ignition switch.

try putting a cold rag on it

Engine, fuel pressure

The bushing (copper) in the bell box is already broken and the starter (when hot) stupidly bites. This is only if everything is fine when cold.

Antokha, it’s normal to start when cold

Are the injectors not overfilling? try to drain the fuel from the ramp and start

Measure the compression and check the timing belt

Miras, you are 100% retractable. Last summer the same thing happened at 4. It won't start until it cools down a bit, right? If you change it, it costs around 500 rubles. This is the reason.

This is interesting: How to install a window regulator on a VAZ 2107

I had the same thing, only the reason was the fuel pump, I replaced it and everything became fine

The coins in the retractor get stuck, remove and clean or a new retractor!

Andrey, that’s right, what is this, can you send a photo?

Miras, here it is, I couldn’t take it off myself. There seems to be no way out without removing the starter itself. I tinkered with it for about an hour and a half and took it to the service center.

Here with the starter it’s... First, take it apart, look, you shouldn’t change everything because of this.

what kind of starter are you talking about? the starter turns

The fuel pump does not create the required pressure, it looks like check it

See crankshaft sensor

Akum. It was exactly the same bullshit. I spent 2 months looking for the problem, replaced everything, but it turned out to be the battery. changed the battery and everything is great

What does this have to do with the drawback, why are you hammering the kid’s brains. The starter turns the engine, you can hear it perfectly

disgraces, the girl is smarter than the boys. Not a shame, huh?

see tags. the sound of the belt came off

Look at the sensor that is located on the thermostat, it is temperature, but it is also responsible for the rich and lean mixture of fuel, I suffered for a long time, and changed 3 pieces (there are enough defects) by the sound, the first time it seemed to grab, this is exactly the same sensor. if the belt had come off, the sound would have been different, because... some valves are open, the starter would turn more easily, as if there was no pressure. For the sake of testing, try to remove the chip from that sensor while it’s hot and turn the starter longer, it will start.

General faults

It is necessary to distinguish between situations when the car simply cannot start, and when the VAZ 2114 does not start when it is hot. In the first case, the reasons may not be related specifically to a warm engine.

The most common faults include:

The battery is low - the charge level is not enough to start the car again.
Problems with the starter - its speed drops, or the relay needs to be changed.
Poor quality fuel - as a result of using gasoline with impurities, fuel system valves or injectors may become clogged.

Important! If black or white residue accumulates on the spark plugs, there may be problems with the ignition system, fuel system filters, or fuel pump. Therefore, when a plaque is detected, the car needs diagnostics.

Another common reason that the engine does not start, either hot or cold, is problems with the ignition module. This is due to a design solution - the ignition system module is attached to the car’s cylinder block. If the windings get too hot, they may burn out. As a result, the spark does not reach one or several cylinders at once.

To check the serviceability of the VAZ 2114 ignition system, you need to:

Check the sparks on the spark plugs - the absence of a spark on several spark plugs at once can cause problems with starting the engine, and indicates a problem with the operation of the module.
Inspect the high-voltage wires - if there is no spark on one spark plug, this indicates a possible wire break. Therefore, it is necessary to inspect the wires for mechanical damage.

Problems associated with the electronic ignition system

It sometimes happens that the engine does not start well when it is cold or frosty. The reason may lie in a faulty battery or simply in its discharge. You can check its status in the following ways:

using a multimeter - the normal voltage between the terminals should be 12.6 V;
using a hydrometer - normal density differs depending on the ambient temperature.

For example, if the engine does not start well at low temperatures even when it is hot, then the reason, obviously, lies precisely in the low battery charge level. Main electrical problems:

the ignition switch is faulty;
one of the two relays installed under the hood - ignition and starter - is damaged;
the starter does not work;
retractor device.

The ignition switch is one of the weak points of almost any car. Moreover, the VAZ 2114 is no exception. Checking its operation is quite simple. All you need to do is dismantle the device and then test all contacts using a multimeter. If it fails, the easiest way is to replace the ignition switch. There is no point in repairing it.

It is not possible to check the ignition and starter relays without opening them. Therefore, the best solution would be to simply replace both of them at once. Their cost in the store usually does not exceed 250 rubles per piece.

You can determine the functionality of the relay simply by sound. If after turning the key it clicks, it means that voltage is coming to it, it is being applied, it works as it should. When the ignition switch is working properly, the relay clicks - the next unit to check is the starter. Usually the problem lies in the retractor.

Sometimes just a light blow with a key helps solve the problem. If you have a heated, well-lit garage, the starter should be removed and carefully inspected. Brushes usually fail. If the car's mileage is significantly more than 150 thousand km, the bearing may fail. After removing the starter, you can try to start it directly from the battery. It's very easy to do this:

the housing must be connected to the zero terminal;
The positive terminal should be connected directly to the retractor using an alligator clip.

If the starter is working properly, it should turn over. If there is no reaction, the problem most likely lies in the retractor.

Fuel system vulnerabilities

The fourteenth VAZ model has an injection engine. Regardless of whether it is equipped with an 8 or 16 valve system, the reasons that the VAZ 2114 does not start when hot may be related to the fuel supply:

too low pressure in the fuel pump - this problem is caused by malfunctions of the pressure regulator on the fuel rail. The pressure in the pump should not exceed 3.2 bar at power modes, but should not fall below 2 bar. The fuel pump may also stop working due to overheating, for example, in hot weather;

The main problems associated with the operation of the fuel system

Engine starting is primarily affected by the following main components of the fuel system:

gasoline level in the tank;
the condition of the fuel line under the bottom of the car;
cleanliness of filters.

It should be noted: even if there is gasoline in the tank, the car may not start. And the reason for this is the low fuel level. The pump may simply not be drawing in enough gasoline. Therefore, before starting to diagnose and inspect all the main components, it is advisable to fill the tank to at least a third. If problems with the electrical part are excluded, you need to pay attention to the fuel line. You need to check:

no breakdowns or leaks in the fuel supply pipe under the bottom;
the condition of the fine filter - often it simply becomes clogged, which leads to a decrease in the pressure level in the fuel system.

It is not possible to check the operation of the fuel pump manually on this car. This can only be done by ear. If, when you turn the key and turn on the ignition, the pump makes noise, then it is “alive”. Otherwise, you need to check whether power is supplied to it. If this is all right, you need to replace the pump. Its cost ranges from 1.5 to 3 thousand rubles, depending on the manufacturer.

You can check the pressure level yourself - just connect a special pressure gauge to the fuel system in accordance with the manual. This will allow you to diagnose the problem. According to the standard, the pressure should be at least 2-2.5 atm. If the indicator is less, then the engine will not start.

Malfunctions of the ECU and sensors of the VAZ 2114

The key element regulating the fuel injection system is the electronic control unit. In the VAZ-2114 this is the domestic “January”, “Itelma”, or, in export versions, “Bosch 7.9”

The ECU collects information from the vehicle's sensors and, based on it, regulates the operation of all systems.

Most often, why the VAZ 2114 does not start when hot is due to malfunctions of the following sensors:

1. Crankshaft position sensor - you need to measure its resistance level using a multimeter and compare it with the calibration data.

2. Temperature sensor - to check its serviceability, it is necessary to cool the sensor, and the resistance should be about 1350 - 1880 Ohms. With subsequent heating, the resistance decreases. If this does not happen, or the resistance level approaches zero, the sensor must be changed.

On a fully warmed up engine, the DT resistance level should be about 87-110 Ohms. Too high or low values indicate a sensor failure.

3. Throttle position sensor - to check it, you need to measure the resistance with the engine running. If, while pressing the gas pedal, the resistance does not change or tends to infinity, the TPS must be replaced. Often the cause of the malfunction is ordinary dirt that clogs the system. Therefore, the throttle assembly must be reassembled and thoroughly cleaned.

4. Air flow sensor - its malfunction is indicated by the fact that the car starts “hot”, but may immediately stall. Also, signs of sensor failure include unstable engine speed (due to the inconsistent composition of the fuel-air mixture) and “dips” when pressing the gas pedal.

The DRMV is involved in starting the engine on a VAZ 2114 with the ECU version “January 7.2” - therefore, the car cannot start with a faulty sensor. If the car has a control unit “January 5.1” or lower, then it is the air flow sensor that causes the engine to stall when “hot”.

Thus, you can find out the reasons why the VAZ 2114 does not start when hot, by carefully inspecting and checking the vehicle systems. But self-checking does not guarantee that the exact cause of the problem has been identified. Therefore, it is recommended to contact qualified specialists and conduct a complete diagnosis of the car.

Other faults

The injector makes it quite easy to determine the cause of the malfunction. But repairs are much more difficult than on cars equipped with a carburetor engine. VAZ 2114 is equipped with engines of various powers. Easier maintenance with 8 valves. If the car takes a long time to start and the exclamation mark is on, then the reason may lie in the following:

incorrect operation of injectors;
poor quality fuel;
low pressure in the ramp.

Often, over a long period of use, the injectors simply become clogged. As a result, they require cleaning. It is difficult to cope with such a task on your own. The solution may be to contact a specialized service. Cleaning is usually performed using ultrasound. Another option is low quality fuel mixture. If the car begins to stall or loses power immediately after refueling, then the problem lies precisely in gasoline.

Lack of sufficient pressure in the ramp is another common reason. It can be measured using a special pressure gauge. Normal pressure is 2-2.5 atm. If it is lower, then the engine simply will not start. If you cannot independently determine the reason for the inability to start the engine, you should contact a service center.

The VAZ 2114 car is easy to repair and maintain. You just need to monitor the quality of the fuel being poured, and also change consumables in a timely manner.

VAZ 2115 injector 8 valves does not start when hot - reasons

WILL NOT START AND STALL WHEN STARTING A HOT VAZ 2115

On a VAZ 2115, it starts perfectly when cold, but when starting hot, it immediately stalls. After it cools down, it starts without problems. What could be the reason?

Poor hot starting is one of the diseases of VAZ cars. Therefore, the question is very common. This happens due to the low quality of spare parts and some design features. It happens that the fuel pump is replaced with a new one, but it turns out to be faulty. “In search of a malfunction” everything is changed, and the problem is revealed already on the second round.

If the car does not start when hot, we recommend checking using the following algorithm:

Point for beginners. Make sure that the problem is related to the “hot” state of the car. Check the battery charge, make sure that the generator is charging (with a multimeter in voltmeter mode). Are there any problems with the starter? If it sometimes turns, sometimes it doesn’t, or occasionally turns poorly, take it to an electrician.
For everyone else. It is advisable to start repairs with diagnostics - it can help save money. A diagnostician will reveal approximately 80% of the causes of the problem, the faulty part will be replaced, and the car will drive and make you happy.

The rest of the information is for the remaining 20% (diagnostics does not reveal problems) and those who do not have qualified specialists in the access area.

INFLUENCE OF SENSORS

Most VAZ-2115 cars operate on the “January 5.1” controller. Crankshaft, temperature and throttle sensors are involved in starting the engine.

DPKV malfunctions usually appear regardless of temperature, but it is worth checking its resistance and comparing it with the data in the calibration table.

A more common malfunction is DT. Remove from position and place in a container with a cooler. We measure the resistance with a multimeter: it should be in the region of 1350 - 1880 Ohms. If you have a thermometer, you can check it using the table. If not, it doesn’t matter either, just heat it to an arbitrary temperature. As T increases, the resistance decreases. On a fully warmed up engine it is 87 - 109 Ohms. If the ohms do not change or drop to 0, change the DT.

The throttle assembly is completely disassembled and cleaned. One of the problems is dirt, which expands when heated and interferes with the normal operation of the injection. If the TPS malfunctions, the car not only does not start when hot, but also “does not drive” (sometimes stalls and does not start) after warming up.

The TPS is checked with an ohmmeter with the engine running. Place the multimeter on the input and output contacts, ask an assistant to press the gas. The readings should change and return to their original values at XX. If the resistance does not change when you press the pedal or the device shows infinity, the sensor needs to be replaced. At the same time we check the IAC. It usually causes the car to be unstable at idle or stall but start.

A malfunction of the mass air flow sensor on cars with January 5.1 is recognized by the fact that the car starts when hot and immediately stalls. The sensor comes into operation only after startup. But on a car with January 7.2, the mass air flow sensor is involved in the start - without it the car will not start.

FUEL PUMP AND RELATED ACCESSORIES

The first malfunction is insufficient pressure in the fuel rail. During operation, the pump heats up and begins to pump poorly. Because of this, the car may stall and not start.

The pressure is checked by installing a pressure gauge. At idle in the system 2.5 atm, in power modes it should increase to 3. With a faulty pump, these indicators may differ between a cold and hot engine. Check in the mode in which problems arise.

One of the problems of the VAZ 2115 is the bypass valve, which, if faulty, begins to “let in” fuel on a heated engine. Bottom line: fuel pressure drops and takes time to build up. Symptoms are a long period of production or its complete absence.

Another reason for a drop in pressure in the system may be a clogged fuel filter or strainer in the tank. When heated, dirt expands and clogs the fuel flow.

IGNITION MODULE

Another problem is the ignition module. This malfunction was more common on cars of the Samara-1 generation. In the case of Samara-2, the quality of the part itself has improved, but the root of the problem remains. The module is attached to the cylinder block, which causes it to get very hot and burn out the windings. As a result, when hot, it is possible to lose spark in one, several or all cylinders at once.

If the car does not start when hot, check the spark. If it doesn't, that's almost certainly the problem. You can usually resolve the issue by replacing the module, but if the problem returns, consider moving the bracket to another location. Most often it is installed in the front part of the engine compartment, near the radiator.

Most problems with poor engine starting when hot are solved using these methods. But less probable ones are also possible: broken wiring, ECU malfunction, etc.

The car doesn’t start well when it’s hot: we look for and fix the problem

Modern cars are gradually moving from the concept of mechanisms to the concept of organisms. This is a highly complex system that requires ideal operating conditions. High engine power, squeezing everything that can be squeezed out of technology, and other features of the modern automobile industry indicate that modern cars must receive maximum care in order to work for a long time. One of the common problems that arise from improper car care is poor engine starting after it warms up. This means that if you park for a few minutes near the store, you will not be able to start the engine properly. The problem lies in two possible types of breakdowns, but there are also extraordinary cases. Today we will deal with the most common problems in this case, and also talk about specific types of problems.

It should be noted that the symptoms of poor hot starting can manifest themselves in different ways. One car refuses to start at all until the engine cools down a certain amount. Another power unit starts only on the third or fourth try, and the third one simply has to be cranked for a long time to start. In any case, no matter what happens to your car in this context, you need to find the problem and be sure to fix it. This task is a harbinger of more serious breakdowns, the repair of which will cost you much more money. So let's figure out why the car doesn't start well when it's hot.

Bad fuel or presence of additives in the fuel mixture

Low-quality gasoline or diesel fuel is one of the most common variants of this problem. But in this case, you can conduct an experiment that will show the true problem of your car. The fact is that low-quality fuel with a poor start when hot will have an even more unpleasant effect when starting the engine when cold. Therefore, it is enough to cool the car, wait for the engine to return to normal and start it. The following problems may also occur with fuel:

Gasoline or diesel fuel may contain an additive that your engine does not accept;
diesel fuel has frozen and acquired a jelly-like form, which is difficult to pump;
there are solid particles in gasoline, the filters are clogged, and it is difficult for the pump to pump the required amount of fuel;
the settings of the engine control system and air supply have gone wrong, one of the valves may have broken;
the idle air valve, as well as the mass air flow sensor (mass air flow sensor) can cause such problems;
It’s just a functional feature of carburetor engines - a very hot unit has difficulty starting.

In the case of carburetor units, everything is quite simple - the engine itself starts very poorly when hot. This is due to the fact that after stopping the car with a hot engine, the temperature in the carburetor area is quite high. Under the influence of temperature, gasoline quickly evaporates and fills all chambers and tubes of the carburetor in a gas state. But the float chamber remains empty. If you decide to start the engine within five minutes of stopping it, you will encounter difficulty starting because there is no liquid fuel in the chambers. The problem can be solved by manual pumping or several attempts to start the power unit. However, there cannot be such a problem with injectors, since the fuel is supplied directly from the main line. Therefore, it is worth looking for other troubles in the fuel supply system.

Too rich or lean mixture - air flow sensor

We mentioned above that problems with starting a car can occur due to the failure of the mass air flow sensor. This element of the car is one of the most sensitive to environmental influences, so they often talk about its breakdown. If starting the engine when hot is very difficult, check the functionality of this mechanism. The following factors may also accompany this failure:

failures when pressing the gas pedal, lack of traction at some moments;
a decrease in power or vice versa - an inexplicable increase in the operating potential of the unit;
complication of engine starting and periodic moments of choking;
explosions inside the exhaust system when the gas pedal is sharply pressed;
unstable speed due to periodic changes in mixture enrichment.

The fuel mixture of gasoline and air must have a certain consistency, which is formed by the mass air flow sensors and some other parts of the electrical and electronic system of your car. If these parts are faulty, you will have to change them and test the car, set up the operation of the new equipment.

The fuel pump has overheated - a common problem in domestic cars.

The fuel pump cools naturally by pumping cool liquid from the fuel tank. But in extreme heat, this liquid cannot be cool in any way, so the fuel pump overheats. This is an unpleasant incident that can lead to the impossibility of starting the car when it is hot. The car may simply stall on the road and not start either with a pushrod or by starting it by turning the ignition key. There are several ways to fix this problem:

take a wet and cold rag, apply it to the fuel pump and periodically moisten it with cold water, cooling it;
open the hood and place the car in the shade, allow all parts of the power unit to cool normally;
change the fuel pump if you have the opportunity to quickly obtain another part of the fuel system;
just wait until the temperature of the fuel pump returns to normal and continue operating the car;
An overheated fuel pump is unlikely to work normally, so it’s better to just change it.

This problem can cause the failure of important parts of the fuel pump, because when it overheats, it stops working for a reason. If after cooling the car nothing changes, then you will have to replace the fuel pump. But usually the car starts when cold, and then drives for several days without any problems.

Problems with poor starting of gas cars in warm weather

Many drivers, having read all the above arguments, will say that they are not valid for their car, since it has a gas installation. It became profitable to drive on gas several years ago, so LPG has found its way under the hood of many car enthusiasts. If in hot weather your car stalls and does not start when hot, you will have to let it cool completely, then start it and go straight to the service station. It’s better not to joke with this question for a number of reasons:

due to high temperatures, certain seals could deteriorate and gas hoses could open;
the working fluid of your car’s fuel system may leak for other reasons;
expansion of gas in the tank at high temperature creates a certain pressure in the system;
It is better not to fill a full gas tank in hot weather, limiting yourself to partial refueling;
It makes sense to consult with a specialist if such a problem begins to occur on your car.

You shouldn’t joke with gas-powered cars at all - even the latest generation of LPG carries a certain danger. If your gas car does not start when hot, it is worth hiring a specialist to solve this problem. This way, you can easily obtain the necessary operating features of the power unit, and you will not expose yourself to the danger of incorrect operation of the fuel supply system. We invite you to look at the experts’ explanations about a poor launch during the busy season:

Let's sum it up

High-quality fuel supply systems rarely fail, so even in the hottest weather, hot cars start without problems. But if such a problem occurs, the driver is unlikely to be able to fix it on his own. There are too many factors of possible breakdowns that are difficult to check without special knowledge and certain tools. Therefore, it is best to show the car to specialists and get a very specific answer to your problem. Most likely, repairing this problem will involve minor sensor replacements and not too expensive procedures.

Therefore, in most cases, turning to the experts will be the key to a successful trip in your car in any weather. You need to contact a service station as soon as signs of poor car starting begin to appear in your case. The sooner you come to the master, the easier it will be for him to help you. And the cost of repairs increases when the visit to the repairman is delayed. Have you ever had a similar situation while driving a car?

Ignition module

Most problems with poor engine starting when hot are solved using these methods. But less probable ones are also possible: broken wiring, ECU malfunction, etc.

Electrical faults

Most of the problems lie here, so we’ll look at each option in detail here:

Nothing happens when I turn the key

On a VAZ 2114, this usually indicates a violation in the ignition switch - starter line, but one of the reasons for the breakdown “for blondes” is a dead battery, do not forget about it (checked with a voltmeter: it should be at least 11.8 V - and with a hydrometer, if the battery is serviceable : at least 1.22 in each jar).

Let's move on. The cause of such a malfunction may be a breakdown of the ignition switch cylinder, and the injector has nothing to do with it. If, when turning the key, new sensations arise (something catches, turning has become easier or, conversely, more difficult), that’s the problem.

Why doesn't the car start if the starter turns but doesn't engage?

Let's look at the reasons why the engine won't start. What are the solutions and what should a person who finds himself in this situation do? We will talk about Samaras with an injection engine, since there are few carburetor ones left today.

If we are talking about the cold season - you did not start in winter, then there are several nuances regarding the engine starting algorithm. Perhaps your candles have flooded or something else. To study this issue more specifically, read the article: How to start a car in cold weather? Where the algorithm is described and, again, possible causes of the malfunction.

Now we will talk more deeply about the technical part, since “winter factors” are no longer needed.

We will describe the problems in the order of the actions taken: that is, starting from the inserted key and ending with the operation of the engine.

Reasons why the injection VAZ 2114 does not start

The design of any modern car, the VAZ 2114 is no exception, is such that the successful production of a car depends on a number of positions. Previously, this was enough for the mechanical pump to supply fuel to the carburetor, and for the spark plugs to produce a spark. Today there are a lot of problems that prevent the engine from starting. An electronic injector requires the participation of several sensors, and the matter is not limited to them. In this article we will tell you why not and how to deal with it.

In general, all causes of malfunction can be divided into two large categories:

Fuel system problems. This group includes any breakdowns as a result of which fuel is not supplied to the engine at all, is supplied incorrectly, or mixture quality errors occur.
Electrical problems. Ignition of the fuel mixture is ensured by sending an electrical signal to the spark plugs. If problems arise here (and there are a huge number of electrical elements), the car will not start.

The most terrible malfunctions can be included in a separate category - for example, a “knocking” VAZ 2114 engine, a broken timing belt and, as a result, bending of the valves. In these situations, expensive repairs cannot be avoided.
