Heres how a 97 is wired, yours is probably the same: PDB fuse 3 to relay to inertia switch to fuel pump. Try opening the inertia switch & see if a new fuse blows.
I opened the inertia switch and put a new fuse in, then turned the key on. The fuse did not blow. I then closed the inertia switch and then turned the key on and the fuze immediately blew. I am assuming now that there is some kind of wiring problem after the inertia switch, or the fuel pump itself.
I do not have a manual for the Expy, does anyone have a wiring diagram for the fuel electronics?
Is that connector under the dash or under the floorboard? The wiring diagram isnt clear on that. If it's under the dash, take a look at the wiring where it goes thru the sheet metal to the underside of the truck.
Also there is a connector at the tank with 6 wires that you can disconnect & see what it does.
After looking at the wiring I found a bare power wire (the brown and pink wire). It was right before the connector that goes to the sending unit/fuel module. I repaired it and all seems to be working as it is supposed to.
