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.
5.
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 fuel pressure is out of specification,
replace fuel pump / fuel tank assembly.
6.
If the pump did not activate (Step 3), disconnect the harness
connector from the fuel pump. Connect a DC voltmeter
across terminals “A” and “C” in the plug on the vehicle
harness side. 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 the terminals “A” and
“C”' in the plug on the pump harness side to check for
continuity within the fuel pump.
NOTE: If there was no continuity between the pump
terminals, replace fuel pump / fuel tank 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 pump, making sure you have clean
connections. Turn on the key switch and listen for the pump
to activate.
NOTE: If the pump starts, repeat steps 1, 2 and 3 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 / fuel tank assembly.
