306 1.6 TU5JP/Z engine 1993
Cold engine have no problem to start.
After 5-10km (not so hot engine) on hot days engine just stop. Start is not posible like no fuel. With Full contact II ignition switch, I dont hear usual 1-2 seconds fuel pump work.
Fuel pump don't work, no power to conector.
Double Relay module is ok, pin 10 have no ground - from ECM pin 3, if I conect pin 10 to ground Relay switch and fuel pump work.
After 15-20 min engine is cooled and I can start engine again.
Please anyone know ECM (ECU) logic in witch state of sensors ECM switch off fuel pump (Double relay). How to know witch sensors fault.
My service don't find any ECM errors.
Please Help
