Fuel Pump Circuit Troubleshooting

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 the ignition switch is turned on. If the

fuel pump does not make noise, check as follows:

1. Turn the ignition switch to LOCK (0).

2. Remove the driver's dashboard lower cover

(see page 20-152).

3. Remove PGM-FI main relay 2 (FUEL PUMP) (A) in

the driver's under-dash fuse/relay box.

4. Turn the ignition switch to ON (II).

5. Measure voltage between PGM-FI main relay 2

(FUEL PUMP) 4P connector terminal No. 4 and

body ground.
