Fuel Pressure Relief Procedure
CAUTION: To reduce the risk of fire and personal
injury, there are necessary to relieve the fuel system
pressure before filler and gauge unit servicing the
fuel system components.
CAUTION: After relieving the system pressure, a
small amount of fuel may be released when servicing
fuel lines or connections. Reduce the chance of
personal injury by covering the fuel line fittings with
a shop towel before you disconnect the fittings. The
towels will absorb any fuel that may leak out. When
the disconnect is completed, place the towel in an
approved container.
1. Remove the fuel cap.
2. Remove the fuel pump relay from the underhood
relay box. Refer to
Fuel Pump Relay section.

Fuel Rail Assembly
Removal Procedure
NOTE:
D
Do not attempt to remove the fuel inlet fitting on the
fuel rail. It is staked in place. Removing the fuel inlet
fitting will result in damage to the fuel rail or the
internal O-ring seal.
D
Use care when removing the fuel rail assembly in
order to prevent damage to the injector electrical
connector terminals and the injector spray tips.
D
Fittings should be capped and holes plugged during
servicing to prevent dirt and other contaminants from
entering open lines and passages.
IMPORTANT:
An eight-digit identification number is
stamped on the side of the fuel rail. Refer to this number
when you service the fuel rail or when a replacement part
is required.
014RY00008
Before removal, the fuel rail assembly may be cleaned
with a spray type engine cleaner. Follow the spray
package instructions. Do not immerse the fuel rails in
liquid cleaning solvent.
1. Depressurize the fuel system. Refer to Fuel Pressure
Relief Procedure in this Section.
2. Disconnect the negative battery cable.
3. Remove the engine cover.
4. Disconnect the throttle position sensor electrical
connector from throttle body.
5. Disconnect the connectors from manifold absolute
pressure sensor, solenoid valve, electric vacuum
sensing valve.
6. Disconnect the vacuum hose on canister VSV and
positive crankcase ventilation hose.
7. Remove the common chamber. Refer to the common
chamber in Engine Mechanical section.
1. Lift up carefully on the fuel injectors. Do not
separate the fuel injectors from the fuel rail.
2. If an injector becomes separated from the fuel
rail, the infector O-ring seals and the retainer clip
must be replaced.
3. Drain residual fuel into an approved container.

8. If removal of the fuel pressure regulator is necessary,
refer to
Fuel Pressure Regulator section.
9. If removal of the fuel injectors is necessary, refer to
Fuel Injectors section.
Installation Procedure
1. If the fuel injectors were removed, install them. Refer
to
Fuel Injectors section.
2. If the fuel pressure regulator was removed, install it.
Refer to
Fuel Pressure Regulator section.
3. Install the common chamber. Refer to common
chamber in engine Mechanical section.
