AnswerThanks for the reply, I'm going to look at some wiring diagrams but can't do so until later today or next morning, I'm on a trip right now, I'll get back as soon as I can.
If you don't hear back from me in about 6 hours post a short reminder for me here.
There are a few circuits connected to that fuse, check to make sure the O2 sensor wiring is not shorted out, check the injector wiring harness for insulation damage, it's a direct short to ground, it could also be caused by a short in the fuel pump or the circuit for the pump, try disconnecting some of the electrical connectors and see if the short goes away.
