Fuel Pump Relay: MPV

Remove fuel pump relay, located in main fuse and relay box, next to battery. Using ohmmeter, check for continuity between relay terminals "C" and "E". See Fig 1 . Continuity should not exist. Apply battery voltage to terminal "A" and ground terminal "B". Again, check for continuity between relay terminals "C" and "E". Continuity should exist with battery voltage applied. If continuity is not as specified, replace fuel pump relay.
