first of all hi and before now some rummeckern, I used the search function and read several posts but unfortunately nobody takes me further. now to my problem: I have an audi 80 b3 1.8s 90 ps pm motor and this just does not start. I get a spark, petrol also arrives and control times also fit. I have a new ignition coil installed. if it is cold and I try to start it he goes on briefly and then runs about 10 sec on so in about 300 – 500 turns and goes dan After that, it can’t be started again. however, if I pull out the petrol pump relay or the securing for the gasoline pump, it goes back to as described above. I tested the thermosensor with the multimeter for resistance and this was in the normal range. I also checked the petrol pump relay and this is also in order. now I don’t know what it could be anymore… please help me, need the car to get to work.
