I was able to jump 12v to the green and orange wire I do have 12v to red and white but now my fule injectors are not firing when I gain spark what's super weird is that I have 3 pcms two new and my old one and only sometimes my check engine light come on at my dash when I turn the key I know that if it doesn't it's a sign of a bad pcm but that can't be the case here any ideas what the hells up with that. As well what I think is weird I can get it so start for a sec or two every one in a great while by cycling the key and I hear everything get proper power fire it up and it dies right away then back to my problem I don't know if the fuseable links could have anything to do with that?

Are you getting 12 volts to the PCM at all the points where it is supposed to have it? Could be a bad ignition switch.

This.

A bad ignition switch can cause all KINDS of weird problems.

Also, do you have a factory service manual so you can trace the wiring properly?
