Fuel pump — testing (Honda Accord 3)

1. The easiest way to check the fuel pump is to listen to it. The noise of the pump running should be audible for 2 seconds after turning the ignition key to the "ON" position. The noise is easier to hear with the gas cap removed.

2. If the pump does not function, continue checking the wiring. On the Accord and Preiude, remove the cargo area carpet.

3. On Prelude, remove the left access cover in the trunk area.

4. Make sure the ignition is in the "OFF" position. Disconnect the connector from the fuel pump.

5. Disconnect the electrical connector from the main relay under the instrument panel on the left side.

6. In the relay socket, use a jumper wire to connect the black/yellow wire terminal to the yellow/black wire terminal (Prelude) or yellow (Accord).

7. Turn the ignition switch to the "ON" position. Battery voltage should appear at the fuel pump connector. On the Prelude, connect the positive lead of the voltmeter probe to the yellow/black wire and the negative lead to the black wire. For the Accord, connect the positive lead of the voltmeter probe to the yellow wire and the negative lead to ground.

8. If the battery voltage is normal, the fuel pump needs to be replaced.

9. If there is no voltage, check the main relay and/or wiring.
