Causes of malfunction
Motorists are wondering: why does the VAZ 2107 engine suffer from injector problems? Many owners of injection VAZ 2107 encountered the fact that the engine began to stall. This malfunction is typical for the entire family of Lada engines. What are the reasons for this effect and where to look for the problem:
- Fuel pump and filter.
- Injectors.
- Spark plugs and high-voltage wires.
- Air filter.
- Throttle.
- valves.
- ECU and sensors.
Causes of cylinder failure
If the VAZ 2107 engine fails, there may be several reasons for this, and in order to find the fault, you need to perform several actions:
- find the faulty cylinder;
- check the spark plugs;
- inspect the wires, injector, injectors, valves;
- check air leaks into the carburetor;
- check operation hot and cold.
Identifying a failed cylinder is quite simple. When the machine is running, you need to remove the high-voltage wires one by one if a carburetor is installed. At this moment, no current will be supplied to the spark plug and the cylinder will stop working. The injector is simpler in that you don’t need to risk disconnecting the wires; it will be enough to remove the chips responsible for controlling the fuel supply. If nothing changes and the engine continues to operate without changes, the faulty cylinder has been found.
The next step is to check the spark plug. Having unscrewed it, you should carefully inspect it. If there is carbon deposits on it, then because of this the spark will not “break through”. It is a mistake to believe that replacement or simple cleaning will solve the problem. Without finding and eliminating the cause, a new candle will take on the same appearance in a short time.
You need to check for spark. To do this, you need to put a high voltage wire on it and bring the metal end to the engine housing. Next, someone needs to crank the starter several times. If everything is normal, a spark should appear. If it is missing, this may indicate:
- wire break or high resistance;
- failure of the ignition coil;
- malfunction of the electronic control unit;
- failure of the crankshaft position sensor;
- The belt is offset by several teeth.
VAZ 2107 injector troits
Hi all. such a problem. VAZ 2107. 2010. injector. You start it up, sometimes it works fine, then it works a little and it starts to fail. the check light is on. maybe someone had it? where to look for a problem? After a restart it stops crashing. I'm sinning on the module

why the second answer, and there
is trouble throughout the entire auto industryneed to see a diagnostician

many faceswhy the second one? I’ll answer there too
this is a problem in the entire auto industry
need to see a diagnostician
need it, need it. I thought maybe someone had similar syndromes. and I’ve heard a lot of bad things about diagnosticians

change the module and believe
that the pump is also an optionMessage from

There is no need to criticize the diagnosticians, there are decent people among them, but first of all, change the spark plugs and buy an on-board computer so that you don’t have to go to the diagnosticians for every little thing,

I looked at the spark plugs, new wires in the dark, they don’t break through, I’ll probably go to a diagnostician

Take old spark plugs and change one at a time and see the difference. Well, set the gap to the correct one on the new ones. And only then for diagnostics.

There can be many reasons: 1. ignition module - you can borrow a working one from someone to replace it for a while and observe. 2. Injectors are clogged - rinse or replace. 3. Valves are adjusted incorrectly - adjust.
Start with the module.
