Don’t start…

Moin people, yesterday my little one disappointed me a little for the first time. Around 8 pm I drove to my sister. Car starts and drives quite normally. No problem at all. I fill up briefly and continue my drive to my sister. At her arrived short discussion and then briefly to buy a tank, some drinks. Also here … car starts and drives as usual. Cirka 2 hours later … I wanted to drive home. Now the shock. Electricity seems to be there enough. It seems as if the engine doesn’t get petrol. So there’s a question … petrol pump, DME relay, DME itself or, if there is a crash sensor ? Because my instructions for use are 50 km away from me … so the first question … is there something like this with the 924S from 1988, if yes, where and how to disable it ? Otherwise it could also be on the fuse for the petrol pump … is the fuse in the safe place … ngskasten, or is the petrol pump secured separately (Where ???) ? What would the alternatives be ? A starter that does not track … or no spark, in the latter, could be next to the DME still the ignition coil or what the following defect, whereby distributor cap and fingers were completely renewed last year. What can be responsible for such a spontaneous error ? If it should be important … the right headlight does not work and has a “weak”. has probably happened when changing the wiper water pump. Suggestions and or solutions ?! Greeting Kester
