I was driving home on the interstate and my 2004 Envoy 4.2 stopped running. I tried to start it a couple times and it still didn't start, I called tow truck to tow it home.
The first thing I knew: my fuel pump could not run. I tried circle ignition couple times and pump still not prime, I opened the FUSE box under the hood and I checked the fuse pump which was good. I removed my fuse pump relay (number 41) and checked the power with my test light. I got power battery supply on one side and the other side pcm control does not have power when I turned my ignition on.
Would you please guide me for things to look for when addressing this issue? ...or could it be that my ignition switch is bad?
