Important

We need rain. Bad.
 
Check the harness for the rear o2 sensor where it goes over the driveshaft. Mine fell on the driveshaft and shorted out after riding on it for a while. 3 feet of e-tape and I could drive home to fix it properly.

There appears to be some "custom" O2 wiring done, for instance the upstream sensor was routed against the exhaust manifold which melted the wires, but I taped up the parts I could see to at least make it better temporarily. It may be a matter of redoing all of the wiring with what I have around here. I don't have time to go cut part of a harness out of a junkyard car before I head out for wheeling this Wednesday. Sometimes I can turn the key to "run" and it pops immediately, other times it will idle fine but if I throw it in gear and stab the throttle it will pop the fuse then. Admittedly I kind of got sidetracked and am in full diagnosing mode instead of just fixing the obvious stuff. I probably ought to rewire the O2 sensors anyway, at least that will rule that wiring out as a problem (they are both disconnected now and I still have the fuse popping).

Or fuel pump is on its way out

I considered that since it was idling rough, that maybe the pump was on its way out. But the pump is on the contact side of the relay and protected by a separate fuse under the hood. The fuse I have blowing is inside the cabin and powers the PCM, TCM, and fuel pump and ASD relays on the coil side. Although at one point I had the PCM/TCM/relays all disconnected, so in theory the fuse should be connected to nothing, and it would still pop as soon as I turned the key to run. Which leads me to believe there could be a short in the harness. Or not. It's very inconsistent which makes troubleshooting a PITA.

Almost Harlan ready.
