SERVICE PROCEDURES
FUEL SYSTEM PRESSURE RELEASE
PROCEDUREÐ2.4/3.3/3.8L
WARNING: RELEASE FUEL SYSTEM PRESSURE
BEFORE SERVICING FUEL SYSTEM COMPONENTS.
SERVICE VEHICLES IN WELL VENTILATED AREAS
AND AVOID IGNITION SOURCES. NEVER SMOKE
WHILE SERVICING THE VEHICLE.
(1) Disconnect negative cable from battery.
(2) Remove fuel filler cap.
(3) Remove protective cap from fuel pressure test
port on fuel rail (Fig. 9) or (Fig. 10).
(4) Place open end of fuel pressure release hose,
tool number C-4799-1, into an approved gasoline con-
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.

(9) Momentarily touch the other end of this
jumper wire to the negative terminal of the battery
for no more than 4 seconds.
(10) Place a rag or towel below the fuel line at the
quick connect to the rail.
(11) Disconnect the quick connect fitting to the
rail. Refer to Quick-Connect Fittings in this section.
(12) Return the fuel pump relay to the PDC.
(13) One or more Diagnostic Trouble Codes (DTC's)
may have been stored in the PCM memory due to the
fuel pump relay removal. The DRB scan tool must be
used to erase a DTC. Refer to group 25, On-Board
Diagnostics.
HOSES AND CLAMPS
Inspect all hose connections (clamps and quick con-
nect fittings) for completeness and leaks. Replace
cracked, scuffed, or swelled hoses. Replace hoses that
rub against other vehicle components or show sign of
wear.
Fuel injected vehicles use specially constructed
hoses. When replacing hoses, only use hoses marked
EFM/EFI.
When installing hoses, ensure that they are routed
away from contact with other vehicle components
that could rub against them and cause failure. Avoid
contact with clamps or other components that cause
abrasions or scuffing. Ensure that rubber hoses are
properly routed and avoid heat sources.
The hose clamps have rolled edges to prevent the
clamp from cutting into the hose. Only use clamps
that are original equipment or equivalent. Other
types of clamps may cut into the hoses and cause
high pressure fuel leaks. Tighten hose clamps to 1
N´m (10 in. lbs.) torque.
QUICK-CONNECT FITTINGS
REMOVAL
When disconnecting a quick-connect fitting, the
retainer will remain on the fuel tube nipple.
WARNING: RELEASE FUEL SYSTEM PRESSURE
BEFORE DISCONNECTING A QUICK-CONNECT FIT-
TINGS. REFER TO THE FUEL PRESSURE RELEASE
PROCEDURE.

(2) Perform Fuel Pressure Release Procedure.
Refer to the Fuel Pressure Release Procedure in this
section.
(3) Squeeze retainer tabs together and pull fuel
tube/quick-connect fitting assembly off of fuel tube
nipple. The retainer will remain on fuel tube.
INSTALLATION
CAUTION: Never install a quick-connect fitting
without the retainer being either on the fuel tube or
already in the quick-connect fitting. In either case,
ensure the retainer locks securely into the quick-
connect fitting by firmly pulling on fuel tube and fit-
ting to ensure it is secured.
(1) Using a clean lint free cloth, clean the fuel tube
nipple and retainer.
(2) Prior to connecting the fitting to the fuel tube,
coat the fuel tube nipple with clean 30 weight engine
oil.
(3) Push the quick-connect fitting over the fuel
tube until theretainer seats and a click is heard.
(4) The plastic quick-connect fitting has windows
in the sides of the casing. When the fitting com-
pletely attaches to the fuel tube, the retainer locking
ears and the fuel tube shoulder are visible in the
windows. If they are not visible, the retainer was not
properly installed (Fig. 12).Do not rely upon the
audible click to confirm a secure connection.
CAUTION: When using the ASD Fuel System Test,
the Auto Shutdown (ASD) Relay remains energized
for either 7 minutes, until the test is stopped, or
until the ignition switch is turned to the Off posi-
tion.
(5) Use the DRB scan tool ASD Fuel System Test
to pressurize the fuel system. Check for leaks.
