Injector code
If the original fuel injector (8) is installed , ensure that the fuel injector is installed into the original position.
If a replacement fuel injector is installed, the correct injector code must be programmed into the electronic control module. Refer to Troubleshooting, "Injector Code - Calibrate" for more information. The code that is required is at Position (X).Note: Record Code (X) before the fuel injector is installed.
Use Tooling (D) to remove any fuel from the cylinder.Note: Evacuate as much fuel as possible from the cylinder before installing the fuel injector.

Position clamp (10) onto fuel injector (8). Align the assembly of fuel injector (8) to the bore for the fuel injector in the cylinder head.Note: Ensure that the clamp is correctly positioned onto the fuel injector.
Push only on injector clamp (10) to install fuel injector (8). Do not apply pressure on any other part of the fuel injector. Ensure that the fuel injector is pushed firmly against the seat in the cylinder head.
Install a new Torx screw (9) to clamp (10). Tighten the Torx screw finger tight.
Remove the cap from fuel injector (8). Install a new seal (4) to fuel injector (8) and to the cylinder head. Ensure that the flange on the seal is flush with the cylinder head.
Remove the plugs from the new fuel injection line. Install the fuel injection line hand tight. Refer to Disassembly and Assembly, "Fuel Injection Lines - Install" for the correct procedure.Note: Ensure that the ends of the fuel injection line are seated into the fuel injector and the fuel manifold. Tighten the nuts hand tight.
Use Tooling (A) to tighten Torx screw (9) to a torque of 27 N m (239 lb in).Note: Tooling (A) must be used to ensure no damage to the fuel injector.
Use Tooling (E) to tighten the fuel injection line to a torque of 50 N m (37 lb ft). Refer to Disassembly and Assembly, "Fuel Injection Lines - Install" for the correct procedure.
Use a deep socket to install harness assembly (6) to fuel injector (8). Use Tooling (F) to tighten connections (7) to a torque of 2.0 N m (18 lb in).
If necessary, repeat Step 1 through Step 18 to install the remaining fuel injectors.
