Ensure that the bores for electronic unit injectors (4) in the cylinder head are clean and free from wear and damage.
If the original electronic unit injectors are to be installed, ensure that the electronic unit injectors are installed into the original location.
If the original electronic unit injectors (5) are to be reused. Install a new O-ring seal (7) to the electronic unit injectors. Remove the protective cap from the nozzle and install a new sealing washer (8). Temporarily reinstall the protective cap from the nozzle.
If replacement electronic unit injectors (4) are installed, the correct Injector codes must be programmed into the electronic control module. The codes are 30 hexadecimal characters in length and are supplied with each injector. The code is on a plate on the top of the injector in Position (X) and a card is also included in the packaging for the new injector. Refer to Troubleshooting, "Injector Code - Calibrate" for more information.
Use Tooling (C) to remove any fuel from the cylinder bore.Note: Evacuate as much fuel as possible from the cylinder bore before installing the electronic unit injectors.
Install new injector clamp (3) to electronic unit injectors (4).
Install the electronic unit injectors to the cylinder head. Ensure that the electronic unit injectors are installed squarely into the cylinder head. Push the electronic unit injectors into the cylinder head. Always handle electronic unit injectors with care.
Install new nut (2) to injector clamp (3). Tighten the nut to a torque of 10 N m (89 lb in) to seat the electronic unit injectors into the cylinder head.
Loosen nut (2) by two to three turns.
Install new fuel injection lines (6) hand tight the tube nuts.
Tighten new nut (2) to a torque of 28 N m (248 lb in)
Tighten the tube nuts for fuel injection lines (6). Refer to Disassembly and Assembly, "Fuel Injection Lines - Install" for the correct procedure.
If necessary, follow Step 5 through Step 15 to install remaining electronic unit injectors (4).

Connect leak off hose assemblies (1) to electronic unit injectors (4). Ensure that the leak off hose assemblies is correctly installed into electronic unit injectors (4).
Install new clips (12) to leak off hose assemblies (1). Ensure that the clips are correctly located onto electronic unit injectors (4).
Connect harness assemblies (5) to the electronic unit injectors.
If necessary, follow Step 17 through Step 20 to install remaining leak off hose assemblies (1) and harness assemblies (6) to remaining electronic unit injectors (4).
Turn the fuel supply to the ON position.
Turn the battery disconnect switch to the ON position.
