    Fuel Problem

    I diagnosed the problem and didn't hear anything from the in tank pump when the ignition was in the on position, so I replaced the in tank fuel pump. Worked fine for a while then cut out, not I think the fuel pump relay might be the culprit.
    The car turns over and even starts but cuts out in 2-3 seconds and doesn't respond to throttle input at all. It just dies out even as I pump the accelerator. All the other electrics work fine it just won't start. Charged the battery up and it held voltage, and the tank is atleast half full but still it won't stay on for more than 3 seconds when it finally does start. Could it be as simple as the relay or is there something else which could mess with the fuel delivery??

    Have you checked the fuel pressure regulator and/or the fuel filter? If all the electrics for the system seem ok, look into these areas. Remember: E30s are old....shit breaks.

    Edit: When you inspect the filter under the car, check the condition of the rubber hoses. Those dry out and crack over time. Not good considering the liquid that runs within.

      Ahh, fack. I can jump the pump if I hotwire if directly from the battery. Soo... yeah just tried that out. No idea anymore. Probably the fpr in light of the newest discovery.

        Other than the fuel pump relay it seems the system is working as it should. Anyone have any other ideas?

          What car? Early cars have an in-tank transfer pump and an external high pressure pump. Late production only has an in-tank high pressure pump.
          The car makes it possible, but the driver makes it happen.

            Ahh, fpr was the culprit. Thanks all.
