Hello, my name is***** it start in Neutral? Do the reverse lights work? Thanks.
Unplug the PCM and check to see if the yellow wire at pin 23 of connector 2 has power with key in start position. Then ground yellow wire at pin 76 to see if starter engages. Let me know, thanks.
That is all you need to check for now and depending on what you find we will go from there. Let me know when you get a chance to do the testing and we will continue, thanks.
