    Another No Start Thread I know but Please Help

    So went to try and start my S50 for the first time.
    Cranks like mad but here is what is going on.

    Main power relay is working.

    The fuel pump relay does not kick on the pump and can be manualy grounded. It has 12 constant and 12V switched and the wire from Pin #1 DME shows 10.5 volts.

    The Coils show 12v switched but no pulse

    The Injectors are not opening. No fuel on he pugs even with the Relay hot wired.

    The DME is a Red Label 413 with a TRM chip. I also cut wire 66 just in case. The DME shows power on some ports so it is getting power.
    It sounds like EWS but I have no EWS.

    Help. I will update as I do further diagnostic tests.

    Sounds like you have the crank sensor problem.

    Hoveringguy has proven that a motor with nothing else but DME power and a crank signal will spark.

    I think the measurement for the CPS is 580 or 1020ish ohms. Its all over the map of where it should be.

    I had a problem no start with mine which ended up being reversed fuel lines.

      IT FUCKIN LIVES. and it is LOUD. Headers only increase the sweet music. It was a ground/fuel hose issue. Now my 3.5 MAF looks dead.

            You should post exactly what your problem is for future people to use your solution.

              I added another harness ground and switched the fuel lines.
