Tools Required

1. Disconnect the negative battery cable.
2. Disconnect the intake air temperature (IAT) sensor connector.
3. Loosen the clamp at the air cleaner assembly.
4. Remove the push pin attachment from the outlet resonator/duct assembly to support bracket.
5. Loosen the clamp at the throttle body assembly.
6. Disconnect the positive crankcase ventilation (PCV) fresh air vent hose at the cam cover.
7. Remove the outlet resonator/duct assembly.
8. Place a shop rag over the throttle body assembly.
9. Using shop air, blow off the dirt and dust near the fuel injector ports.




Caution: Whenever fuel line fittings are loosened or disconnected, wrap a shop cloth around the fitting to collect fuel. Place the cloth in an approved container.

10. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
11. Disconnect the SA9127E after the pressure has been relieved.
12. Position the engine harness away from the fuel rail assembly.



13. Disconnect the fuel rail bracket and nut at the rear of the cam cover.




Notice: An open-end wrench must be used to support the fuel line to rail connection during loosening/tightening to avoid damaging the fuel rail assembly.

14. Disengage the fuel transfer lines at quick contract from the fuel line using the SA9805E .
15. While supporting the fuel rail assembly with an open-end wrench, loosen the transfer line fitting at the fuel rail.



16. Position the fuel line away from the rail assembly without disconnecting the degas hose.



17. Disconnect the electrical connectors at the fuel injectors.
18. Remove the fuel rail assembly attachment bolts.

Notice: Use care in removing the fuel rail assembly to prevent damage to the electrical connector terminals and spray tips. The fuel injector is serviced as a complete assembly only. Support fuel after fuel rail is removed in order to avoid damaging fuel rail components. Since it is electrical, it should not be immersed in any cleaner.

19. Remove the fuel rail assembly by carefully pulling the rail backward and upward to remove injectors from the cylinder head.
20. Move the fuel rail assembly rearward while slightly rotating to remove the fuel rail assembly.




Notice: When cleaning or servicing the fuel rail, care must be taken to assure that the plastic fuel rail surfaces that mate to the injector O-rings are not scratched.

Important: Whenever the fuel rail is removed for service, upper and lower O-ring seals must be replaced. The injectors can be serviced individually if required.

21. Remove the fuel injector retaining clips (3).
22. Remove the fuel injectors (5) from the fuel rail.
23. Remove and discard all injector O-ring seals (4, 7) by using a small pick.

1. Transfer components to the new fuel rail if the rail is being replaced.
2. Install the new upper and lower O-ring seals (4, 7) to injectors (5).
3. Install the injectors (5) to the fuel rail assembly.
4. Install the isolators (6) with new seals to injectors.
5. Install the injector retaining clip (3).




Important: Lubricate the O-rings at injector isolators prior to installing injectors into the cylinder head.

6. Install the fuel rail to the cylinder head.

Notice: Refer to Fastener Notice in the Preface section.

7. Install the fuel rail bolts.

Tighten
Tighten the fuel rail-to-cylinder head L61 to 10 N·m (89 lb in).




8. Position the fuel line assembly.




Notice: An open-end wrench must be used to support the fuel line to rail connection during loosening/tightening to avoid damaging the fuel rail assembly.

9. Install the fuel line bracket and bracket bolt.

Tighten
Tighten the transfer line fitting-to-fuel rail L61 to 10 N·m (89 lb in).




10. Connect the fuel rail bracket and nut to the cylinder head.

Tighten
Tighten the fuel line bracket bolt L61 to 10 N·m (89 lb in).

11. Connect the fuel line to transfer line.

Important: To assure proper connection and to fully seat the retaining tabs, lightly pull apart the connection.

12. Insert the fuel transfer line into the fuel line connection. An audible click should be heard.



13. Remove the shop towel from the throttle body.



14. Install the outlet resonator/duct assembly into position.
15. Connect the PCV fresh air bent hose assembly.
16. Tighten the clamp at the throttle body assembly.
17. Position the outlet resonator/duct assembly up with a support bracket and install the push pin.
18. Tighten the clamp at the air cleaner assembly.
19. Connect the IAT sensor connector.
20. Connect the negative battery cable.

Tighten
Tighten the battery terminal bolts to 17 N·m (13 lb ft).
