FUEL SYSTEM

6. If none of the conditions exist, the fuel sender FUEL PUMP TEST
assembly is faulty. Replace the fuel pump assembly. If a fuel delivery problem is suspected, make certain the
Refer to Fuel Pump Replacement procedure. fuel pump filters are not plugged, that the pump is being
activated through the ECU, all electrical connections are
properly secured, the fuses are good, and a minimum of
7.0 volts is being supplied. If during starting the battery
voltage drops below 7.0 volts, the ECU will fail to operate
the system.
NOTICE
A minimum of 10 volts is needed to properly run the fuel
pump.

WARNING
Fuel is extremely flammable and may cause severe
burns, injury, or death. Do not use any device that
produces a flame or electrical devices that may spark
around fuel or fuel vapors.

1. Remove the passenger seat from the vehicle.
2. Cover the fuel line connection at the fuel tank with a
shop towel and disconnect the line from the fuel
pump outlet.
3. Install the Fuel Pressure Gauge Adapter (PV-48656)
in-line between the fuel pump outlet and fuel line.

4. Connect the hose from the Fuel Pressure Gauge Kit
(PU-43506-A) to the test valve on the Fuel Pressure
Gauge Adapter (PV-48656). Route clear hose into a
portable gasoline container or the vehicle’s fuel tank.
5. Turn on key switch to activate the pump and check
the system pressure on the gauge. If system
pressure is within specifications, the ignition switch,
ECU, fuel pump, and pressure regulator are working
properly. Turn the key switch off and depress the
valve button on the tester to relieve the system
pressure.
Fuel Pressure:
58 ± 2 psi (400 ± 14 kPa)

NOTICE
If the fuel pressure is out of specification, replace the
fuel pump assembly.

6. If the pump did not activate (Step 5), disconnect the
harness connector from the fuel pump. Connect a
DC voltmeter across terminals “3” (Red/Blue) and “4”
(Brown) in the plug on the vehicle fuel pump
harness. Turn on the key switch and observe voltage
to ensure a minimum of 7 volts is present.
NOTICE
If the voltage was below 7 VDC, test the battery, ignition
switch, relay(s), wiring harness and ECU.
