Tools Required

Notice: 

1. Relieve fuel system pressure. Refer to Fuel Pressure Relief .
2. Disconnect the IAT sensor connector (1) from the IAT sensor.



3. Remove the air cleaner intake duct (3).
4. Clean the fuel rail assembly and fuel pipe connections.



5. Remove the quick-connect fittings (2), (4) at the fuel rail. Refer to Metal Collar Quick Connect Fitting Service .



6. Remove the fuel pressure regulator vacuum hose.



7. Remove the PCV air tube.



8. Remove the fuel rail end-point bracket retainer nut.



9. Remove the fuel injector electrical connectors from the fuel injectors.
10. Lay the harness aside.



11. Remove the bolts (2) from the fuel rail.
12. Raise the fuel injectors from the intake manifold with J 43013 fuel injector removal tool.

Important: Store the fuel rail assembly in a clean secure location away from heat sources.

13. Lift the fuel rail and remove the fuel rail.

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.

Notice: 

Important: Always use new upper and lower O-rings lightly coated motor oil.

1. Install the fuel rail assembly on to the intake manifold until the fuel injectors are fully seated.




Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the bolts (2) to the fuel rail assembly.

Tighten
Tighten the to bolts to 10 N·m (88 lb in).




3. Install the fuel injector electrical connectors to the fuel injectors.



4. Install the fuel rail end-point bracket retainer nut.

Tighten
Tighten the nut to 10 N·m (88 lb in).




5. Install the PCV air tube.



6. Install the fuel pressure regulator vacuum hose.



7. Install the quick-connect fittings (2), (4) at the fuel rail. Refer to Metal Collar Quick Connect Fitting Service .



8. Install the air cleaner intake duct (3).
9. Install the MAF sensor electrical connector (1) to the MAF sensor (2).



10. Connect the IAT sensor connector (1) from the IAT sensor.

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

11. Install the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
12. Inspect for leaks.

12.1.

Turn ON the ignition for 2 seconds.

12.2.

Turn OFF the ignition for 10 seconds.

12.3.

Turn ON the ignition.

12.4.

Visually inspect the fuel system for fuel leaks.




13. Tighten fuel filler cap (1).
14. Install the rear seat cushion. Refer to Rear Seat Cushion Replacement .



15. Install the fuel injector sight shield (1) to the engine.
16. Install the fuel injector sight shield nuts (2).

Tighten
Tighten the nuts to 3 N·m (27 lb in).
