The only thing at 12 is the main ground wire that goes over to the SAI pump. Been looking at wiring harnesses and it looks like the one I mentioned by the AOS & corner of the intake are the ground terminals for the coils and other things on bank 1. That is good & secured to the engine. So if it is a wiring issue it is going to be one of the other wires, a break (unlikely since it does fire) or a chafed wire.
