Re: GMT400 Wiring Woes

I haven't had to do anything since I put the motor in a couple years ago. I pulled the oil pressure sending unit. Noticed there was some oil clean back on the plug so I went ahead and replaced it. As well as the fuel pump, fuel pump relay, fuses, ignition module, and distributor. As far as I can tell it's a short somewhere. I didn't have time to play with it this weekend. Had to finish up a toyota head job and a transfer case in a tahoe.
