for the ranger gurus

94 ranger 2.3 fuel pump wont kick on. ive checked the relay, its good. inertia switch is good. i can hook a 12v source to the backside of the inertia switch and fuel pump runs, so the wiring from the i.s. is ok. i can cross the relay socket from 12v constant to accessory (fuel pump) with inertia switch in place and the pump runs. any ideas? one thing it isnt getting the ignition signal from switch, but even if i give the "ignition" side of the relay 12v, the pump still doesnt kick on. im puzzled.

fuse? sounds to me like either relay is bad or the wiring connector itsself. also check grounds. ive had to run a completly new wire from the relay to the pump in some cass.

i.s. have a tendency to go bad i had to replace one im a friends truck

i say the fuse under the hood. thats the same thing mine did my fuse didnt look blow change it and see.
