Fuel Pump Relay (NAVAJO)
- Remove fuel pump relay (located under power distribution box on right inner fender). Connect 12 volts to terminal "C" and ground terminal "D". Check for continuity between terminals "A" and "B". If continuity is present, relay is okay. If continuity is not present, replace relay.
- Turn ignition on. Ensure 12 volts present on Red and Black/Yellow or Yellow wires. If 12 volts is not present, repair circuits from Electronic Engine Control power relay, battery or power distribution box.
- Connect 12 volts to terminal "A". Fuel pump should operate. If not, repair wiring to inertia switch, fuel pump, fuel pump ground, or replace fuel pump.
