So, now it got me too… Recently it has happened more often that the engine runs out after starting. After 4-5-6 attempts the engine runs as if never had been anything. 2 weeks ago I installed a new petrol pump relay, since no more problems. This morning again 5 attempts, then it ran first. I would like to go through the possible sources of error systematically and need your help for it. The car is here again this afternoon, then I will be wrong for now. The first problems usually occurred when the engine was running for a short time, but it wasn’t really warm. This morning we had 10 degrees here, so it wasn’t really cold. But that’s just speculation from me now.
