Thread: PCM or not wired right

Threaded View

    Here is where we are at now, its actually where we began.



    the yellow wire has been reconnected to its other half. he then took the purple solenoid wire (from the old harness) and ran it to the starter, turn the key, nothing happens. which is odd, as his truck was running fine with the old engine installed, so this solenoid wire should activate the starter fine but it doesnt.

    just for the hell of it, he tested the solenoid wire on the new pcm with his multimeter, to see if he would get 12v with the key in start position...nothing.

    otherwise, he is getting power at the PCM where it should be and the fuel pump relay on the new harness is clicking, as it should.

    this is with the new harness connected to the Neutral safety switch (NSW). for chits and giggles, we even attached the old NSW to the new harness connection, then we connected the old and new NSW to the old harness NSW connection...nothing.
