'97 F150 PCM location
You guys are correct. The computer is behind the battery. I pulled the wire harness off and then was able to remove it from inside the cab. Honestly, it took about five minutes -- much easier than my '93 F150 where I had to remove the fender well.
I did check the megafuses and I had current going to them and coming out of them. Is there any way, short of taking just the computer to the dealership, of having it checked? If it is going to cost a hefty charge to have it examined, I might as well spend the money and buy a new one and take my chances on returning it.
Thanks,
Kyle Campbell
