Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Pump Test
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 listen to the fuel fill port with the fuel fill cap removed. The fuel pump should run for 2 seconds when ignition switch is first turned on. If the fuel pump does not make noise, check as follows:
- Remove the rear tray (see TRIM REMOVAL/INSTALLATION - REAR TRAY AREA ).
- Remove the access panel from the floor.
- Turn the ignition switch OFF.
- Disconnect the fuel pump 5P connector.
- Connect the PGM-FI main relay 7P connector terminals No. 4 and No. 5 with a jumper wire.
- Turn the ignition switch ON (II).
- Check that battery voltage is available between fuel pump 5P connector terminal No. 5 and body ground when the ignition switch is turned ON (II).
- If battery voltage is available, check the fuel pump ground. If the ground is OK, replace the fuel pump (see FUEL PUMP/FUEL GAUGE SENDING UNIT REPLACEMENT ).
- If there is no voltage, check the wire harness (see PGM-FI MAIN RELAY CIRCUIT TROUBLESHOOTING ).
