tainer. Connect other end of hose C-4799-1 to fuel
pressure test port (Fig. 11). Fuel pressure will bleed
off through the hose into the gasoline container. Fuel
gauge C-4799-B contains hose C-4799-1.
(5)Replace Pressure test port cap when fin-
ished doing pressure test.
FUEL SYSTEM PRESSURE RELEASE
PROCEDUREÐ3.0L ENGINE
(1) Remove the Fuel Pump relay from the Power
Distribution Center (PDC). For location of the relay,
refer to the label on the underside of the PDC cover.
(2) Start and run engine it stalls.
(3) Attemp restarting engine until it will no longer
run.(4) Turn ignition key to OFF position.
CAUTION: Steps 1, 2, 3 and 4 must be performed to
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
the positive side of the battery.
(8) Connect one end of a second jumper wire to the
remaining injector terminal.
CAUTION: Supplying power to an injector for more
than 4 seconds will permantely damage the injector.
Do not leave the injector connected to power for
more than 4 seconds.
