Disconnect harness assembly (1).
Remove bridge assemblies (3).
Do not reuse the injector hold down bolts. New injector hold down bolts must be used.
If the injector hold down bolt is loose during the removal procedure, inspect the injector bore for wear and debris. Replace the clamp and spacer.
Remove bolt (4) and spacer (5). Discard bolt (4).
Place an identification mark on electronic unit injectors (2) for installation purposes. Each electronic unit injector must be reinstalled in the original location in the cylinder head.
Use Tooling (A) to pry beneath the base of clamp (6) and free electronic unit injector (2).
Remove clamp (6) and electronic unit injector (2) from the cylinder head.Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Use Tooling (C) to remove the fuel and oil from the cylinder. Evacuate as much fuel and oil as possible from the cylinder before installing the electronic unit injector. Several evacuations may be necessary.
Use Tooling (D) to clean the carbon deposit from the inside of the electronic unit injector sleeve. Tooling (E) is available to clean loose material from the bore of the electronic unit injector sleeve and the cylinder.
Use Tooling (F) to clean the carbon from the seat area that is inside the electronic unit injector sleeve.
Install the O-ring seals on the electronic unit injector. Lubricate the top two O-ring seals with clean engine oil.

The E-Trim value must be programmed into the engine control module when you install a new injector . Program the injector confirmation code into the engine control module. E-Trim Value (X) is a 12-digit alphanumeric code that is supplied with the data sheet that comes with the new injectors. Injector Confirmation Code (Y) is a four-digit numeric code. Both of the codes are located on the top of electronic unit injector (2). Use the following menu to program the E-Trim value.

Injector Code Calibration
When an electronic unit injector is replaced, the new electronic injector code must be programmed into the engine's personality module software by using the calibration menu on the Electronic Service Tool. If the new electronic injector code is not entered, the characteristics of the previous electronic unit injector is assumed.If it is not possible to immediately reprogram the electronic injector code into the personality module software, the engine will not be severely harmed. The new electronic injector code should be reprogrammed as quickly as possible in order to optimize engine performance.
Position electronic unit injector (2) and clamp (6) in the cylinder head.
Install spacer (5) and new bolt (4). Tighten the bolt to a torque of 55 10 N m (41 7 lb ft).
Install bridge assemblies (3).
Connect harness assembly (1).End By:
Install the rocker arms and the rocker arm shaft.
