1988 Ford Ranger Repair Question
1988 Ranger Fuel Pumps wont turn on.
Any chance that truck has an integrated controller module or some thing similar??? Usually, on the car models, was mounted on the radiator upper support, under the sight shield... small black box with a big connector bolted to it, lots of wires.. in that box were fuel pump relay, ac relay, and others... I don't know if they're serviceable, on the cars the box was riveted...

I did some work on the pickup this weekend. I discovered that somewhere in the EFI electronics there is a switch sticking or broken. I re-routed my fuel pump wiring to my acc. in my fuse box put a toggle switch on the dash. Fuel pumps work great now. Thanks for your help.

I don't know if this will help.
On my 93 explorer, there are 2 possibilities. There is a fuel pump relay that is in the power distribution box. This is under the hood. Look for a box with a bunch of relays and fuses in it. I personally have had 2 relays go out in this box. There is also a 20a fuse to this circuit in the box.
My Explorer also has an "inertia fuel shutoff" sensor that will open the circuit to the fuel pump on impact.
On mine, it is behind the instrument panel on the passenger side. From the diagram I have, it appears to be mounted to the fire wall.
