I accidentally hit send before I was done..
Anyways they had trouble starting this and they hooked the jumper cables backwards and shorted the battery. I put a new battery in and found no fuel pressure or spark or injector pulse.
I tested the crank sensor and replaced it. Starts right up now but I felt a bad misfire. I scanned it with a older snap on scanner and got code 27 for injector circuit 5 and 6.
I put a noid light on those two and it stays constantly illuminated. There is no pulse but the other four have a pulse.
Think they could have messed up the computer or fried the wiring?
Just my luck being the only car guy in the family so now this is my problem.

I don't think so, but give it a try. Look at the part numbers on both PCMs and see if they match.
