Normally, I start a cold engine. It has around 1100 rpm at the beginning, 800 rpm at idle after warming up. The idle speed is stable. There is a smell of gasoline from the exhaust (rich running). The car runs normally with the engine warmed up. He is restless with the cold. The problem is that at a certain temperature, after about an hour of stationary car, it cannot be started. It will only start after several attempts. Sometimes it doesn't start at all, I remove the pump relay and spin the engine, when it starts, I quickly return the relay and the engine starts. When the engine cools down, I start normally. Coil, spark plugs, cables, distributor, pump, fuel filter, blue sensor - everything is new. Today I took out the injectors and sent them to the inspection. Has anyone had the same problem?

It sounds like the engine is running "too rich", with too much fuel, if it will start with the fuel pump disconnected.Originally posted by 123go View Post
Possibly the ECU thinks the engine is still cold when it is actually hot.
You can check the resistance of the various temperature sensors/switches used by the ECU. I would start with that to see if they are reading correctly at cold & hot engine temperatures.

On the network, I found which pins are to which sensors, but I didn't find what values to measure. Would you have a link?Comment

The previous owner had an eye for detail and left me, for example, a cable connected to the coil at a clamp. It worked for quite a long time before a few wires broke off. ..Attached FilesComment

Ahoj, asi to byl ten modrý senzor. Vyměnil jsem ho za úplně nový a funguje bez problémů. Děkuji za vaši pomoc.Comment
