Removal Procedure
- Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure .
- Clean all engine fuel pipe connections and areas surrounding the engine fuel pipe connections before disconnecting the engine fuel pipe connections to avoid possible contamination of the fuel system.
- Remove the fuel feed pipe retaining clip (2).
- Disconnect the engine fuel feed pipe (3) from the fuel rail (1). Refer to Quick Connect Fitting(s) Service (Metal Collar) .
- Disconnect the evaporative emission (EVAP) pipe (5) from the EVAP canister purge solenoid valve (4). Refer to Quick Connect Fitting(s) Service (Plastic Collar) .
- Remove the upper intake manifold. Refer to Intake Manifold Installation - Upper in Engine Mechanical.
- Disconnect the fuel injector harness from the fuel rail.
- Disconnect the coolant temperature sensor and camshaft position sensor electrical connectors.
- Disconnect the main fuel injector electrical connector.
- Remove the fuel rail retaining bolts (1).
- Remove the fuel rail assembly (2).
- Remove the injector O-ring seal from the spray tip end of each injector.
- If removing the fuel injectors from the fuel rail is necessary, refer to Fuel Injector Replacement .
CAUTION:
In order to reduce the risk of fire and personal injury that may result from a fuel leak, always install the fuel injector O-rings in the proper position. If the upper and lower O-rings are different colors (black and brown), be sure to install the black O-ring in the upper position and the brown O-ring in the lower position on the fuel injector. The O-rings are the same size but are made of different materials.
IMPORTANT:
When servicing the fuel rail assembly, precautions must be taken to prevent dirt and other contaminants from entering the fuel passages. It is recommended that the fittings be capped, and the holes be plugged during servicing.
