connection between the OBDII under the dash to the PCM
96 Camaro 5.7l Lt1. Is there a fuseable link or relay between the OBDII under the dash connection and the PCM in the car, I have another computer now and my program still will not read the PCM nor will my scanner, the car still will not run. like I said the problem came up when I tried to flash a program in, there was a bumping noise that came from the under dash area, I think somewhere in the wiring there is a problem, I have checked the wiring diagram and found nothing in between the units, but there has to be some thing that I have missed or a wire burned in too to keep the laptop and the PCM from talking to each other.
TunerCat if you are there, can the data converter be the problem how can you check the data converter,
