Why would I only have 4 volts with right PCM and 8 volts with the one from the gas job? Thanks for all your efforts

I forgot about that whole crazy mess.

Sorry 'bout that.

Yes, I would throw an ignition switch at it. They are pretty cheap if you get an aftermarket one. It's not hard to change, but you do need a security torx bit (T-15 I think) for the screws. All that has to come off is the column cladding (3 screws from the bottom) and you are looking at the switch.
