Fuel Pump
Testing
lf you suspect a problem with the fuel pump, check that
the fuel pump actually runs; when it is oN (ll), 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 (ll).
lf the fuel pump does not make noise, check it as follows:
1. Fold the left rear seat cushion forward, and remove
the base frame cover (see section 20).
2, Remove the access panel from the floor.
3. Make sure the ignition switch is OFF, then discon-
nect the fuel pumP 5P connector.
4. Connect the PGM-FI main relay 7P connector termr-
nal No. 4 and No, 5 with a jumper wire.
