Electric Fuel Pump/Fuel
Level Sensor
The electric fuel pump and fuel level sensor are not ser-
viceable components. If either component fails, it must
be replaced.
TESTING
1. Turn the ignition switch ON and listen for a momen-
tary “whirring” sound of the pump building pressure.
If the sound is heard (10 seconds), no electrical
checks are necessary. Turn the ignition switch OFF.
2. Disconnect the gasline hose from the fuel rail; then
install a suitable pressure gauge.

CAUTION
Do not force the water pump housing into the crankcase
or sever engine damage may occur.
CAUTION
After operating the vehicle for the initial 5-10 minutes,
stop the engine, allow the engine to cool down, and
check the coolant level. Add coolant as necessary.
! WARNING
Whenever any maintenance or inspection is made on
the fuel system during which there may be fuel leakage,
there should be no welding, smoking, open flames, etc.,
in the area.
AT THIS POINT
Prior to removing the electric fuel pump, the following
check should be performed to determine that removal
is necessary.
! WARNING
Gasoline may be under pressure. Place an absorbent
towel under the connector to absorb any gasoline spray
when disconnecting.
