I took my truck to get dyno tuned and found that I had a p0200 code. When he opened up his diagnostic center on his lap top we found that 2 injectors (7 and 4) were reading higher than the other injectors. Frustrated I took my truck back home and begin researching the problem. Here is my concern. When I hook up my multimeter to chassis ground and other end to the pink wire on injector harness I get 12v on all injectors. When I use my multimeter and test across the pin on the harness side I get 5v key on engine off with truck running 8.5-9v. Is that normal ? I'm thinking I should have 12v across the pins. I swapped computers, rencently bought new injectors , checked and rechecked and added grounds. Need help please
