Several years ago I helped a friend diagnose a non-functioning fuel pump. We found no continuity between the pump and the inertia switch. We also dug up some old remarks regarding the wiring loom that carries the wires from the fuel pump to the inertia switch. It makes a sharp bend near the front of the driver's side front fender. I believe the loom runs across the front of the car and back down the driver's side and through the inertia switch and other dash appliances. Apparently some cars developed a break in some of the wires at this sharp bend. We ran a wire directly from the pump to the switch and everything worked fine. Perhaps the wire you found from the pump to the switch was to correct this. Bruce Benson > This isn't exactly an answer, but...
