rail.
(2) Connect Fuel Pressure Gauge C-4799B to test
port (Fig. 7).
CAUTION: When using the ASD Fuel System Test,
the ASD relay and fuel pump relay remain energized
for 7 minutes or until the test is stopped, or until
the ignition switch is turned to the Off position.
(3) Place the ignition key in the ON position.

Test. The ASD Fuel System Test will activate the fuel
pump and pressurize the system.²If the gauge reading equals 338 kPa (49 psi)
3.3L uses approximately 379 kPa (55 psi) further
testing is not required. If pressure is not correct,
record the pressure.
²If pressure is above specifications, check for a
kinked or restricted fuel return tube (from filter to
pump module). If the fuel return tube is not pinched
or restricted, replace the fuel pressure regulator.
²If fuel pressure is below specifications, refer to
the diagnosis chart for Fuel Pressure Below Specifi-
cations.

relieve high pressure fuel from within the fuel rail.
Do not attempt to use the following steps to relieve
this pressure as excessive fuel will be forced into a
cylinder chamber.
(5) Unplug connector from any injector.
(6) Attach one end of a jumper wire with alligator
clips (18 gauge or smaller) to either injector terminal.
(7) Connect the other end of the jumper wire to
