Fuel Pump: Testing and Inspection

WARNING: Do not smoke during the test. Keep open flame away from your work area.

If you suspect a problem with the Fuel Pump, check that the Fuel Pump actually runs; when it is "ON", you will hear some noise if you hold your ear to the Fuel Fill Port with the Fuel Fill Cap removed. The Fuel Pump should run for two seconds, when Ignition Switch is first turned on. If the Fuel Pump does not make noise, check as follows:

1. Remove the access panel in the trunk.

CAUTION: Be sure to turn the Ignition Switch "OFF" before disconnecting the wires.

2. Disconnect the 2 P Connector.





3. Disconnect the Programmed Fuel Injection (PGM-FI) Main Relay Connector and connect the BLK/YEL "5" wire and YEL "7" wire with a Jumper wire.





4. Check that Battery voltage is available at the Fuel Pump Connector when the Ignition Switch is turned "ON" (positive Probe to the YEL wire, negative Probe to the BLK wire).
- If Battery voltage is available, replace the Fuel Pump.
- If there is no voltage, check the Fuel Pump ground and Wire Harness.
