FUEL INJECTION
Fuel Pump Test
NOTE: FUEL GAUGE SENDER TEST - To test fuel
gauge sender function, refer to Chapter 10.
The fuel pump/tank assembly is non-serviceable and must be
replaced if determined to be faulty. If a fuel delivery problem is
suspected, make certain the 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.
1.
Remove the cap from the fuel test valve.
2.
Connect the pressure hose of the Polaris pressure tester
(
PN PU-43506
) to the test valve on the fuel rail. Route the
clear hose into a portable gasoline container or the
equipment fuel tank.
3.
Turn on the key switch to activate the pump and check the
system pressure on the gauge. If system pressure of 39 psi
±
3 is observed, 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.
NOTE: If the pressure is too high or too low, replace
the fuel tank assembly.
4.
If the pump did not activate (Step 2), disconnect the plug
from the fuel pump. Connect a DC voltmeter across
terminals “A” and “C” in the plug, turn on the key switch
and observe if a minimum of 7 volts is present. If voltage
is between 7 and 14, turn key switch off and connect an
ohmmeter between the terminals “A” and “C”' on the pump
to check for continuity.
NOTE: If there was no continuity between the pump
terminals, replace the fuel tank assembly.
NOTE: If the voltage was below 7Vdc, test the
battery, ignition switch, wiring harness and ECU.
5.
If voltage at the plug was good, and there was continuity
across the pump terminals, reconnect the plug to the pump,
making sure you have good, clean connections. Turn on the
key switch and listen for the pump to activate.
NOTE: If the pump starts, repeat steps 1 and 2 to
verify correct pressure.
NOTE: If the pump still does not operate, check for
correct ECU operation by plugging in a known-good
ECU of the same model.
NOTE: If the pump still does not operate, replace the
pump/tank assembly.
Fuel Pump / Tank Assembly Replacement
NOTE: All EFI units utilize quick connect fuel lines.
NOTE: The fuel pump cannot be replaced as an
individual part, the entire fuel pump and fuel tank is
replaced as an assembly. Refer to your parts book
for the proper part number.
WARNING
Check the fuel test valve for any possible fuel
seepage after performing any tests or
procedures. 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.
Normal Fuel Pressure: 39 psi. ± 3
WARNING
Always wear safety goggles when working with
high pressure or flammable fluids. Failure to do so
could result in serious injury or complications.
