1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .



2. Remove the fuel injector electrical connector.
3. Release the fuel rail to intake manifold locking tab by pushing toward center of intake manifold.
4. Remove the fuel injector up out of intake manifold using J 41081 between the bottom of injector and intake manifold.




Important: It may be necessary to release the adjacent injector(s) from the intake manifold to allow increased fuel rail movement for injector access.

5. Spread the injector retainer clip (10) to release injector from fuel rail.



6. Remove the fuel injector assembly (1).
7. Remove the upper (3) and lower (2) injector O-rings seals from the injector.
8. Discard the injector O-ring seals.

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.

1. Lubricate the new upper (11) and lower (13) O-rings with clean engine oil.
2. Install the new upper (11) and lower injector (13) O-rings on the injector (12).
3. Install the fuel injector (12) into fuel rail.

•	Ensure injectors are aligned by orientating electrical connector perpendicular to crankshaft.

•	Push in the retainer clip (10) far enough to engage retainer clip with machined slots on rail socket.




4. Snap the fuel rail down on to intake manifold.
5. Install the fuel injector electrical connector.
6. Add fuel to the fuel tank.
7. Tighten the fuel filler cap.
8. Install the negative battery cable.

8.1.	Turn ignition switch to ON position for 2 seconds.

8.2.	Turn the ignition switch OFF for 10 seconds

8.3.	Turn the ignition switch ON.

8.4.	Check for fuel leaks.





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.

9. Install the intake manifold top cover.

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