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 first turned on. If the fuel pump does not make noise, check as follows: Turn the ignition switch OFF. Remove the glove box (see page 20-79), then remove the PGM-FI main relay 2 (A). LHD model: RHD model: Turn the ignition switch ON (II).

NO - Repair open in the wire between the PGM-FI main relay 1 and the PGM-FI main relay 2. Measure voltage between the PGM-FI main relay 2 4P connector terminal No. 1 and body ground.
