Fuel Pump Relay (Fox)
- Ensure fuel pump fuse (No. 13) is not blown. If okay, remove fuel pump relay. Note terminals numbers molded on fuse/relay panel. With ignition on, check for battery voltage between the following locations:
- terminal No. 46 and ground
- terminal No. 48 and ground
- If voltage is not present, current is not reaching the relay. Repair as necessary and check fuel pump operation. If voltage is present, check for battery voltage between the following locations:
- terminal No. 48 and terminal No. 50
- terminal No. 46 and terminal No. 50
If voltage is not present, terminal No. 50 (ground circuit) is open. Repair as necessary and check fuel pump operation.
- If voltage is present, check for battery voltage between terminal No. 50 and terminal No. 51. If voltage is not present, the ignition signal is not making contact to the fuel pump relay. Repair as necessary and check fuel pump operation.
- If no faults can be found but the fuel pump operates when the relay is by-passed, replace fuel pump relay.
