Tools Required

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.

1. Disconnect the negative battery cable.

Important: Leaking fuel injectors may contaminate the engine oil with fuel.

2. Relieve the fuel system pressure. Refer to the Fuel Pressure Relief .
3. Remove the fuel rail assembly. Refer to Fuel Injection Fuel Rail Assembly Replacement .




Notice: Use care in removing the fuel injectors in order to prevent damage to the fuel injector electrical connector pins or the fuel injector nozzles. Do not immerse the fuel injector in any type of cleaner. The fuel injector is an electrical component and may be damaged by this cleaning method.

4. Spread the injector retainer clip to release the injector from the fuel rail.
5. Remove the fuel injector.
6. Remove the injector O-ring seals from both ends of the injector.

Important: When ordering new fuel injectors, be sure to order the correct injector for the application being serviced.

1. The fuel injector assembly is stamped with a part number identification (2), a manufacturing date (3), a week code (1), and a production plant number (4).

Inspect the new injectors in order to ensure installation of the correct part.




2. Lubricate the new injector O-ring seals with clean engine oil.
3. Install the new injector O-ring seals on the injector.
4. Install a new retainer clip on the injector.
5. Push the fuel injector into the fuel rail injector socket with the electrical connector facing outward.



6. Install the fuel rail assembly. Refer to Fuel Injection Fuel Rail Assembly Replacement .
7. Tighten the fuel filler cap.
8. Connect the negative battery cable.
9. Inspect for leaks.

9.1.	Turn the ignition switch ON for 2 seconds.

9.2.	Turn the ignition switch OFF for 10 seconds.

9.3.	Turn the ignition switch ON.

9.4.	Inspect for fuel leaks.

10. Program the transmitters. Refer to Transmitter Programming in Keyless Entry.
