Fuel Pump Relay (Cabriolet)
- Ensure fuel pump fuse (No. 5) is not blown. If okay, remove fuel pump relay (No. 2) from fuse/relay panel See Fig 1
. With ignition on, check for battery voltage between the following locations:
- terminal No. 2 and ground
- terminal No. 4 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. 1 and terminal No. 2
- terminal No. 1 and terminal No. 4
If voltage is not present, terminal No. 1 (ground circuit) is open. Repair as necessary and check fuel pump operation.
- If voltage is present, check for battery voltage between terminal No. 1 and terminal No. 5. 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 only when relay is by-passed, replace fuel pump relay.
