Hello! I'm trying to find an interesting problem. The engine starts and runs good when it cold until it is turned off after warming up. Experimetally found a way to start the enigine - spray fuel into the intake manifold with the pedal pressed, it starts and then runs normally. It looks like there is some kind of startup prohibition, according to the engine and fuel system diagnostics, there are no errors. There is pressure in the fuel rail, the fuel pump relay turns on.
This vehicle is from USA, after an accident. There are only 2 errors - about airbag and hood ajar circuit (B3006-01, B3006-02, B3006-04). I've checked the hood switch and it works properly. May it be the problem with autostart system ?

ECT sensor seems to be good. The temperature rises normally. After the engine stops, the sensor continues to show the true temperature, but the engine no longer starts untill it cools down

Crankshaft sensor, that is symptom when it fails
I can provide wiring diagrams, parts number, technical service bulletins, part replacement procedures etc.. for Citroen/Opel. No pin code or key cut codes.
