I have been tracing back all the wiring, and the injectors were getting power, just not grounding out. None of his lights are working either, but the truck has spark.

Just to test and try and get the truck firing, I tried running the ground wires from the injectors off the main harness to the body. I got a good reading across the injectors now. Still didn't start, his gas was very watery and stale. So were gonna try and flush it out and put some fresh gas in and try again.

Any other suggestions to fix this wiring issue? I've tried to trace the main harness, and see that the main negative terminal goes to the engine block on top, and the computer runs to a ground on the firewall. Theres 2 wires coming off his firewall ground that have weird ends and no connection to them. Someone also said that putting the new starter in may have caused some issues with the electrical, since it started when the new one was put in.

I can't really do much without finding a wiring schem. if anyone has one it would be greatly appreciated. Some redneck had this truck before and has bu chard this harness.

Oh, and is the pcm located on the firewall? I see a little black box mounted near the wiper motor with a few wires coming out but don't know what it is.
