So yesterday while cruising with my beloved vert, the car suddenly died. No warnings , no hesitation just dead. Dash lights came on and that was it. I cruised to the side of the road and tried to diagnose the mystery.
The car crank strong but nothing else.We start the diagnostic.
First the fuel pump was not working there was no fuel being pumped to the fuel rail. Checked the FP relay...not working no power to it....so we jumped the relay the fuel pump starts working there is fuel flowing but still no start.So now we missing spark?....and while we were unable to diagnose the no spark issue and were ready to call for a tow, the car suddenly came back to life.I drove it home no problem. Parked it restarted it few times... working.
But now i want to find out what your take on the problem is. Anyone had something like this happened to him?
The car is 1987 325i Convertible with 19lbs injectors and m30 AFM.
And scorpion exhaust. Other than that is stock.
Thank you for any input.
