FUEL SENDER TEST
If the fuel gauge reading on the instrument cluster is not
working, or if the display reading differs in large
comparison to the fuel in the tank, perform a resistance
test on the fuel sender.
Disconnect the fuel pump / sending unit connection and
measure the resistance. If out of specification, replace
the fuel pump assembly.
Fuel Sender Resistance Specifications:
Full: 6 ± 1 Ω
Empty: 90 ± 4.5 Ω
FUEL PUMP TEST
If a fuel delivery problem is suspected, make certain the
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.
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 Adaptor (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 Adaptor (PV-48656). Route the clear hose
into a portable gasoline container or the vehicle’s
fuel tank.
