Hi all, I have a G4 extreme in my rally car and if I turn the engine off after a stage, I can not restart engine, all power supplies are good, fuel pump not being primed. let cool down or cool down with a damp rag and will start. No faults while running. Is there a protection device in the ecu for over temp. it is mounted on a panel on transmission tunnel witch does not feel too hot. Any ideas please!!!
