    m50 no start...spark but no fuel prime

    I had to swap the pan on my m50 and while in there I pulled the intake manifold to tidy up wires/fuel lines etc

    I tested the motor while still in the air and it ran for a few seconds and I shut it off. The next day I torqued mounts, put the engine covers on, and put the car on the ground and it tried to start but I haven't been able to get it run for more than a second or two.

    The fuel pump wont prime on ACC but I have spark. I'm suspecting the busted looking resistor on the injector harness ground wire. The only cover I've ever had for this is the bigger injector engine cover. I'm thinking it may have shorted the already damaged resistor when I was installing it.

    Could this ground wire be my problem and how can I test it???

    measure the resistance on both ends of the resistor. if it's very high (likely infinite) then the resistor is busted.

    I'm not sure if it's actually a resistor though, it could be a capacitor..

      Resistance measured ~240 ohms. All my other grounds seem to have have visible grounds seem to be good. Still no start. Bad ecu?

      Here is the resistor

        DME is throwing an injector #5 code repeatedly...any suggestions?

          Resurrecting thread from the dead. I've been searching for this resistor to replace my broken one. Anyone have part numbers?
