Vaz 2107 injector stalls while driving. Why does a VAZ injector start up and stall right away? Motor stalls on the move - reasons

Carburetor, pin.

Hello everyone.

First, decide what problem with fuel or with ignition. and then you even change everything. When it stalled and does not start, check if there is a spark on all the candles and if there is benz in the carburetor. poke it, the elephant sprinkles?

Most likely the problem in the distributor is a contact group, a bearing, a capacitor ...

I had a wonderful defect - the rubber hose connecting the gas tank and the fuel line cracked. Accordingly, gasoline went on and on, unpredictably. A trifling defect, but how he got my brains, words cannot convey! How many times have I gone over the ignition and carburetor, and where I have not suddenly stopped! Oh, how I remember it!

Hello everyone.

The car began to stall on the move (with a stuck gear, usually 3-4 / while squeezing the clutch - while stopping - at idle).
It began with the fact that it stalled right from the exit from work. Turned the key - started up - drove on. He did not attach any importance.
In a day or two, the "stronger" stalled (in the same place). Didn't start for a minute. Started up - drove off. After a while, it began to stall on the go. I drive 20-50, in 2-4 gears, it can stall for a second, the car immediately wants to stop, this cannot be overlooked, of course). In a second - two with the pusher starts up, goes on. The next morning I got up right in the stream. Plant did not want at all. Dragged home, changed the slider, started up and drove without problems, 10 days. Then the same thing started. On the first day, it stalled at the exit from work, started up and drove off, the next day it stalled a couple of times on the move - it started from the pusher, the next day it stalled right in front of the house and was able to roll in neutral (50 meters remained). I especially liked it when on the same day I tried to die at the turn. Twitched as if in convulsions, as if riding a horse, like in a movie brake-gas, indescribable sensations. From the outside it looked awful, I guess). Changed the slider (again, yes). Started up with a half turn. A minute later it died out and that's it. I looked - the fuel filter is empty, I turned the starter a little - the filter did not fill. I tried to pump fuel manually - no effect. I changed the pump, candles (it was time already), explosive wires, the car went like new. After a couple of days it started again. Today it has stalled at work and a couple of times in the city. Tomorrow I will stall in the stream ...) Stability is a sign of mastery.
During all these situevins, the car was not very frozen (at least the arrow at the beginning of the white zone).

Where to dig? I can't imagine (not a specialist in repair).
Save, otherwise the city will rise because of me)

There are two main reasons for carburetor ones: 1.Jets. 2. Vacuum. There are 3 more reasons, but not the main one, the electromagnetic idle speed controller. mainly manifests itself at speeds up to 60 km / h. Twitching, stalls at idle, dull acceleration with twitching.

I have not read to the end about the filter and the fuel pump. Dear, have you changed the mesh in the tank for a long time and checked the fuel pump yourself? A membrane for example? Okay, it doesn't pump manually (the camshaft rested against the stem) But from the starter for 3-5 seconds. the filter must be filled !!!

Despite the development of the auto industry, the classic VAZ models are still in great demand in the CIS countries. The latest models of the "Classic", namely the VAZ-2107, were equipped with an injector intake system. It is more reliable than a carburetor one. But what to do if the VAZ-2107 starts up and stalls? The injector is a more complex system. But the problem can be solved by hand. Let's take a look at how to do this.

Does the starter turn?

First, you need to check the voltage in the vehicle's on-board network. For normal start-up of the machine, this indicator should not be lower than 12.5 V. To accurately measure the voltage, you must use a voltmeter.

A starter is a mechanism that requires a large starting current. It is this assembly that turns the crankshaft to start. Therefore, if the VAZ-2107 (injector) does not start, the reasons may be trivial - low battery voltage. The elimination method is to charge the battery. You should adhere to indicators of 12.5-14 Volts.

Starter breakage

If there is a short in the body or armature wiring, replace the damaged part. How do I check an item? To do this, you need to use a multimeter. One wire is connected to the friction point of the brushes, and the second is connected to the armature axis. If the arrow of the device deviates from the values, this may be a malfunction of the armature or winding. Check the brushes. They should move easily, and their springs should be elastic and press well on the anchor. After replacing damaged components, start the engine again.

Ignition system

What to do if the VAZ-2107 (injector) does not start with a well-charged battery and a working starter? The reasons may lie in the ignition system. Here it is of the contactless type. The first thing to check is the condition of the candles. They can simply be "flooded". Unscrew the elements outward and inspect the condition of the electrode. If there is plaque, the part should be cleaned in an alkaline solution and screwed back. You should also check the gap between the electrode. For this, a special probe is used. The normal reading should be between 0.7 and 1 millimeter.

What if the indicator does not correspond to the norm? The electrode can be bent. But do it carefully. If the indicator is less than normal, use a minus screwdriver. If more, tap with an electrode on a metal part (for example, an engine valve cover). It will be useful to check the candles for the generation of a spark. For this, a special pistol is used. The spark itself should be blue. If the parts have traveled more than 60 thousand kilometers, they should be replaced. Also, when this period is reached, those coming to them from the ignition distributor change.

When the candles are filled

If the VAZ-2107 injector does not start well (it catches, but does not start), then the combustion chamber is overfilled with gasoline. The normal fuel to air ratio should be 1:14. This problem often occurs on these vehicles. The fuel pump pumps a lot of gas when starting. By the way, on injection motors it is electric, submersible. Installed directly into the tank.

How to dry candles without removing them? To do this, open the throttle valve when starting. It is mechanical here and is activated by pressing the throttle trigger through the cable drive. This will allow more air to enter the combustion chamber and the engine will start immediately.

Trambler

The VAZ-2107 uses a distributor ignition. If it is necessary to check the condition of the contacts on the high-voltage wires. Condensation forms on them when the season changes. The distributor has five outputs.

Four of them go to the cylinder plugs, and one (center) goes to the ignition coil. A white coating often forms on the metal ends. Because of it, the slider will not be able to transmit impulses to the coil. By the way, it will be useful to check the ignition distributor itself. The detail looks like this.

If it is burnt, the part should be replaced. The price of a new item is 150 rubles. If a spark forms on the ignition coil when starting the engine, the high-voltage wire must be replaced. He also "breaks through" the candlesticks. You can see this in the dark. Small sparkles of blue are visible near them. In this case, the wires are changed as a set. They are inexpensive. New elements cost about 700 rubles.

Electric pump problem

Previously, one of the main problems on the domestic "Classic" concerned the fuel pump, which was constantly overheating. But in the fuel-injected "seven" it is electric and is cooled by the gasoline itself, which is in the tank. If no electricity is supplied to the element, the car simply will not start. The first thing to look out for is the fuse box.

It is written on the cover which one is responsible for the fuel pump. If the fuse is blown, replace it. A 15 or 20 Amp cell can be used.

Determine serviceability visually

Is it possible to check if there is voltage to the fuel pump without a multimeter? To do this, when you turn on the ignition, you should carefully listen to its work. When the key is turned to the third position, it should emit a characteristic hum. It can be heard in the rear of the passenger compartment. If it is not there and the VAZ-2107 (injector) does not start, the problem is in the voltage supply. It is worth checking the pump relay. It should emit characteristic clicks. Experienced motorists carry spare relays and fuses with them in case of sudden breakdowns. This relay is located on a shelf under the glove compartment.

Low pressure

Why does the VAZ-2107 (injector) not start? Problems can be hidden in the low level of the fuel line pressure. For a normal start of the injection engine, at least 2.8 atmospheres is required. You can check this by disconnecting the supply tube from the ramp. Use a pressure gauge for this. Malfunctions with the pump can occur due to frequent overheating. But how does this happen if it is a submersible type? The fuel pump kills driving on an empty tank. If the light comes on, do not overtighten with refueling. The cost of a pump for an injection "seven" is 3 times higher than for a carburetor one.

Filter status

The following situation also happens. You arrived at your destination, turned off the engine for two minutes, got into the car and could not start it again. What to do if VAZ-2107 (injector) This may be due to a clogged fuel filter. Its replacement period is about 50 thousand kilometers. Also the fault of the difficult start is the dirty air filter.

If it has traveled more than ten thousand kilometers, then it must be replaced. Otherwise, you will run into startup problems.

VAZ-2107: the injector starts up and immediately stalls

In this case, check the MAF sensor. It is located just behind the plastic filter housing.

This element perceives information about the air flow and transmits it to the control unit. As a result, the electronics decides on the composition of the combustible mixture. The unit can intentionally adjust the concentration of fuel and air. The service life of the DMRV sensor is 150 thousand kilometers. The element can give false readings if contaminated. Because of the VAZ-2107, the injector does not start, or it works and immediately stalls. You should also check the condition of the air connections for leaks. Replace if necessary.

DPKV

If, with a working fuel system, the VAZ-2107 (injector) car does not start, if it is faulty, the control unit will stop supplying fuel due to the lack of information about its position. The cost of this element ranges from one to one and a half thousand rubles.

Conclusion

So, we found out for what reasons the VAZ-2107 car does not start. As you can see, you can find and fix the malfunction with your own hands, and for a small price.

In this article, we will take a closer look at the situation when a carburetor engine passenger car(VAZ 2108, 2109, 21099, 2105, 2107 and their modifications), starts and stalls due to a carburetor malfunction. The malfunctions of carburetors 2105, 2107 Ozone, 2108, 21081, 21083 Solexi of their modifications will be considered.

Malfunction symptoms

— The engine starts, runs for a few seconds and stalls, repeated starts are ineffective.

- The engine starts up with difficulty, after running for a short time it stalls, after restarting it starts and runs.

- The engine starts up and immediately stalls, starts up again and stalls again and so on several times, but then it still starts to work.

Causes of malfunction

There is no fuel in the float chamber

Pump it up with the manual priming lever on the fuel pump.

The diaphragm of the trigger is damaged or it is not adjusted

Disassemble the body of the starting device, replace the diaphragm with a new one. Adjust the starting device.

Clogged fuel and air jets, emulsion wells and main metering system pipes

It is necessary to remove the carburetor cover, unscrew the jets, remove the tubes, rinse and clean them, clean the wells, blow everything with compressed air and put it back. The image shows that it is worth cleaning the carburetor 2105, 2107 Ozone.

Unscrew the air jets on the Solex carburetor, take them out together with the emulsion tubes. There are fuel jets at the bottom of the opened wells. We turn them out with a thin long slotted screwdriver. We clean, rinse with acetone and blow with compressed air.

In this article, we will talk about such an unpleasant problem as engine stalling and bad starting. Consider the main reasons why the engine stalls on idle and on the go. In addition, let's talk about why the engine does not start hot, as well as options for solving each of the above problems.

Common reasons why singles stall:

1. The most common is the idle speed regulator (sensor), which is directly related to the idle speed of the engine. It is quite simple to check whether the breakdown is in it. If the car does not start when you crank the starter, operate the gas pedal, the engine should start. If the revs start to float immediately after you take your foot off the pedal - 99% that the reason is in the idle speed control. The solution is, this will take the owners of VAZ a minimum of time.

2. The second probable reason why the engine stalls on Idling- throttle valve problems. This nuisance is being treated - a banal one.

3. If after cleaning the problem persists, we make the assumption that the reason for which the engine stalls at idle may be the TPS (throttle position sensor). The problem is solved in a way, the procedure is not complicated and really doable with your own hands.

There are frequent cases when the engine stalls on the move, as they say for no reason. Below will be listed the most likely and most common reasons for which this may occur.

Motor stalls on the move - reasons

1. Poor-quality fuel is the first thing that comes to mind for most of us, besides, it is necessary to start from this the search for the cause of the engine stopping on the move. You will be "lucky" if this happens immediately after refueling, in which case it is safe to say that the problem is in the fuel. It is treated by draining fuel and.

2. Candles. As a rule, suspicion falls on them most often, after bad fuel, of course. Everything is simple here - unscrew the candles and check their condition, if necessary.

3. Fuel filter... A clogged filter can interrupt the fuel supply, causing you to gas and the engine stalls on the move. It is enough to eliminate the malfunction.

4. Air filter. Everything is the same as with the fuel, if it is clogged, then the air does not flow, therefore the fuel-air mixture comes out re-enriched and the candles are simply flooded. In addition, due to lack of air, the engine will choke, that is, the power will drop, and the process of combustion of the mixture in the cylinders will not be able to take place, in the end the engine will stall. To eliminate this malfunction, it is enough to replace the air filter.

5. Defective fuel pump - the second "suspect". If your fuel pump is not all right, then the car will behave this way, stall on the move, or the engine will not start at all. The problem is solved by checking the pump, repairing it, or.

6. Battery. Oxidized battery terminals or poor contact can cause engine stalling. Check the terminals, clean them if necessary or replace the battery.

7. If the engine stalls on the move and no longer starts, the generator may also be the cause. A failed generator does not charge, as a result, the on-board network of the car is powered exclusively by the battery, and as you know, it will not last for a long time. As a result, you, unaware that the car is running on a battery, continue to move until it is completely discharged. It is treated - and.

6. In advanced cars, the reasons can also be with electronics and various sensors. If you are not strong in this and all of the above nodes and parts are normal, then it is better to turn to specialists, otherwise you can replace the floor of the car with no use by typing ...

Why the engine stalls hot, a well-heated engine won't start?

1. The first possible reason is. While driving, a large amount of air passes through it, which is why the carburetor is seriously cooled, at the same time the fuel that passes through it also cools. As a result, the carburetor temperature is several times lower than the engine temperature. Because of this feature, problems arise, after a long journey, you turn off the engine and make a short stop, at which time the carburetor starts to get very hot from the hot engine body. The remaining gasoline in the float chamber from the high temperature begins to evaporate, filling the voids - the air filter, the intake manifold and the carburetor itself. Air locks are formed, and not a drop of fuel remains in the float chamber.

The solution to the problem is quite simple - press the gas pedal halfway several times and try to start the engine. This will make the mixture leaner and release excess evaporation. It should be noted that problems with hot starting can also be due to a similar problem, only due to the fault of the fuel pump or the fuel line. This typically occurs in hot weather, when vapor in the fuel system or pump creates air pockets that prevent fuel from entering the carburetor.

2. The second possible reason for the strange behavior of a warm engine is problems with the starter. Make sure that when you try to start the engine, the starter motor cranks, rather than just clicking or not responding at all. If so, one of the above options was confirmed. it is necessary to check the starter. If you are on the road, then the check can be reduced to an elementary check of the starter power cable or other visual operations. If you get home, make a detailed one. In case of malfunction or replacement.

3. Alternatively, the reason when the engine does not start on a hot one may be a dead battery due to the reason described above, when the generator did not charge and the battery sat down completely.

Well, it seems like they haven't missed anything !? That's all for today, we hope the article will help, tell you the cause of the breakdown and help in solving your problem. If you know other reasons, as well as ways to solve them, you can supplement the article using the comment form. Thank you for the attention.

Hello everyone today I want to talk about the reasons why your VAZ 2107 car stalls, and due to this unpleasant annoyance, you can no longer continue driving on your iron horse. Today we will try to consider the main reasons why your engine stalls. Of course, unfortunately, there are a lot of such reasons.
The first reason is problems with the idle speed regulator (IAC), usually the car stalls at idle. Pxx can fail due to contamination, and this leads to the fact that the stem wedges. To make sure you need to remove the IAC from the seven and rinse thoroughly in case of contamination. It is advisable to use a liquid that washes away the oil well.

The second reason due to which the VAZ 2107 stalls is the alarm (if, of course, it is installed), in most cases the alarm works with the electric circuit of the gasoline pump, but where does this ask you? And besides, the unscrupulous mechanic who connected the alarm to you could do his job poorly from here and problems may follow. Moreover, if they did everything on twists, then over time it weakens, and everyone write letters, as they say. Power to the pump ceases to flow, as a result of which the VAZ 2107 will not start.

The third reason is that the fuel mixture is too rich. Verify this version it is possible by unscrewing the candles, if the contacts of the candles are covered with black carbon, this means that the mixture is too rich. For how much gasoline is supplied to the cylinders, the position of the throttle valve, as well as the readings of the temperature sensor, is responsible; on a VAZ 2107 car, this sensor is located on the left in the back of the block head. If it becomes necessary to replace the temperature sensor, then you will have to drain some, then part of the antifreeze.
Failure of the mass air flow sensor (DMRV) on the VAZ 2107 also leads to an enrichment of the mixture. You can check the operation of the DMRV using a multimeter. If the voltage is more than 1.002 volts, then it will have to be replaced.

The fourth reason is the strong depletion of the combustible mixture. As a result, your "Seven" will also stall. This is mainly due to air leaks. The main places of suction are the gaskets of the intake system, or loosening of the fastening in the places where they stand. To find air leaks, a smoke generator is usually used to see where the smoke is being drawn in.

And the fifth reason is the vacuum brake booster. Since air leaks can also pass through it. This happens due to a leaky diaphragm. You can determine a faulty vacuum tank on a VAZ 2107 by pinching the hose that connects the vacuum amplifier and the intake manifold, if the engine does not stall, then most likely you will have to change the vacuum tank.

Well, that's all we have considered the main reasons why the VAZ-2107 car stalls, if you had other reasons, then write in the comments. Goodbye to everyone.
