(I know there is another thread similar to this but was unsure whether to reply to it or start a new one.) I have an '89 Ranger Extended Cab, 2.9, auto. It was totaled last year. I have driven it about 500 miles since the frame was straightened. After finishing it for a title inspection, replacing salvage panels with new, it decided not to start. There is a breakdown in power or signal between the fuel pump and it's relay. The fuel pump, only 1,5 years old, works perfectly well when voltage is applied directly to it and I jumpered the relay connector just to double check. The inertia switch's continuity also checks out. I also jumpered its connector. When the key is turned on and fuel should be pumping and pressurizing the system nothing happens. The wiring diagram shows only these three components and the ECM in the circuit. Any ideas?
