Check continuity between fuel pump relay terminals "A" and "B" and terminals "C" and "E". See Fig 1 . Continuity should be present between fuel pump relay terminals "A" and "B" and not between terminals "C" and "E". Using fused jumper wires, connect positive battery terminal to fuel pump relay terminal "A". Connect negative battery terminal to fuel pump relay terminal "B". Continuity should be present between fuel pump relay terminals "C" and "E". Replace relay if continuity is not as specified.
