Default Short in Passenger Fuse panel for Fuel Pump NEED 1992FSM

Hey all,
I have a short someplace. It is driving me crazy. The fuel pump fuse in the passenger compartment blows with the ignition on. I have unplugged the Fuel Pump Relay, the ECM, the ICM and it still blows. Does anyone have any ideas? I am looking for someone (God Bless their Soul!) that may be able to scan me some diagrams. Like I said, it is the fuse under the passenger side kick panel. It is a 20amp fuse there and it is blowing 25'* just as quick. HELP!

I won't be able to get to my FSM till later this evening. But examine the wiring between the relay and the fuse.

hmmm
where to start...
I had to replace the tranny... the crank sensor... gone through numerous ICMs and coils...
the problem started out really weird.. I could start the car, rev it, put it in reverse, put it in drive and SLOWLY roll forward... if I applied too much pedal, it would blow the fuse. NOW it won't even start... I apply power, it blows the fuse. Does that help?

IT DID RUN AFTER TRANNY INSTALL AND CRANK SENSOR AND ICM'*.

Hop under the hood and look for pinched wires around the back of the trans where the gear selector cable goes in. Also check around the crank and cam sensors on the ICM harness (wiring to ICM/Crank/cam) for any pinching.

Realizing the FP fuse is blowing....it is probably tied back to one of those. Also there is a FP test point on a green connector behind your battery. Maybe that somehow got pinched.

PROBLEM FIXED!!! Thanks for the diagram it helped!!! The oil pressure sending unit had 12 volts going to it, it was shorted internally... 20 bucks later with a new sensor I am back in business!! Thanks all!!
