I believe the PCM isn't getting powered up. Can someone point me to a link where I can find the schematics for the engine electrical and a pinout of the PCM to see what wire powers up the PCM?? The dealer said he couldn't communicate with the PCM and when the key is on the fuel relay doesn't fire and consequently the engine won't start. Gages all work except for the volt gage and the fuel gage which fires off the fuel pump relay. That all goes back to ground thru the PCM.
