6. If the pump did not activate (Step 5), disconnect the
harness connector from the fuel pump. Connect a
DC voltmeter across terminals “3” and “4” 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.
NOTE: If the voltage was below 7 VDC, test the
battery, ignition switch, relay (s), wiring harness
and ECU.
7. If the reading is between 7 and 14 volts, turn key
switch off and connect an ohmmeter between
terminals “3” and “4”' at the white fuel pump
connector to check for continuity within the fuel
pump.
NOTE: If there was no continuity between the
pump terminals, replace the fuel pump assembly.
8. If voltage at the plug was within the specified range,
and there was continuity across the pump terminals,
reconnect the plug to the fuel pump, making sure you
have a clean connection. Turn on the key switch and
listen for the pump to activate.
NOTE: If the pump starts, repeat steps 3, 4 and 5
to verify correct pressure.
9. 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 fuel pump assembly.
Fuel Pump Replacement
1. Move the vehicle to a well ventilated area. Shift the
transmission into Park and turn the ignition key off.
2. Remove the passenger seat to access the fuel
pump.
WARNING
Always wear safety goggles when working with high
pressure or flammable fluids. Failure to do so could
result in serious injury or complications.
3. Be sure the top of the fuel tank is clean (Item 1). If it
requires cleaning, hand wash the top of the tank to
ensure no debris will enter the fuel system when the
fuel pump is removed.
WARNING
Failure to clean area around fuel pump may lead to
debris entering the fuel tank during service. Excessive
debris in fuel tank may cause premature wear of fuel
pump and/or clogging of internal fuel filters.
4. Ensure that static has been discharged by touching a
ground source such as the engine or frame.
