Xpi Injector

[Rawze]

YUP, you have to put the injector trim code onto the ECM after installing the new injector as well. Thanks for the reminder Mr. Hag.

[Mr Hagg]

Just incase you need the info before you can set up a account:

Record the injector trim codes that are listed on each injector.
Record the cylinder location where each injector will be installed.
NOTE: The injector trim codes are nine-character alphanumeric codes, located on the solenoid at the top of the injector.
CAUTION

Avoid pushing on the injector terminals while installing or seating the injector. The injector terminals will be damaged if excessive force is applied.

Make sure the injector bore is clean.
Lubricate the injector o-ring with clean engine oil.
Align the notches in the injector with the tab on the injector hold-down clamp.
Place the injector and hold-down clamp in the cylinder head in the proper orientation (fuel inlet toward the high-pressure fuel connector).
Push down on the injector hold-down clamp near the injector to make sure the injector is properly seated.
Use the injector shipping sleeve to make sure the injector is seated in the injector bore.

NOTE: If a new injector is being installed, a new fuel connector must also be used.

Start the injector hold-down clamp capscrew, but do not tighten.

To prevent damage to the fuel connector, push downward on the threaded end of the fuel connector to lift the fuel connector tip and help the connector tip seat properly against the injector.
Install the high-pressure fuel connector, making sure the end of the high-pressure fuel connector is in the injector inlet port.
( They dont say this in the book but make sure the connector screw is clean. We take scotch brite pad and clean the nut well. )

Tighten the injector hold-down clamp capscrew. (Step 1 of 2)
Torque Value: 20 n.m [177 in-lb]
NOTE: This is not the final torque for the injector hold-down clamp.

Lubricate the threads on the fuel connector retaining nut with clean engine oil.
Start the high-pressure fuel connector retaining nut and tighten partially. (Step 1 of 2)
Torque Value: 20 n.m [177 in-lb]

NOTE: This is not the final torque for the high-pressure fuel connector retaining nut.

Tighten the injector hold-down clamp capscrew. (Step 2 of 2)
Torque Value: 80 n.m [59 ft-lb]
Tighten the high-pressure fuel connector retaining nut. (Step 2 of 2)
Torque Value: 77 n.m [57 ft-lb]

Trim Code Installation Instructions: INSITE™ 7.3 Feature Pack 1 and Newer
1. Connect the batteries. Refer to the OEM service manual.
2. Connect INSITE™ electronic service tool to the ECM.
3. Select "Advanced ECM Data".
4. Select "High-Pressure Common Rail Injector Setup"
5. Read the information listed under the "High-Pressure Common Rail Injector Setup" and "Instructions" headings.
6. Click on the "New Bar Code" section for the respective cylinder and enter the new bar code.
7. After all the injector trim information is entered, select "Apply". Turn the keyswitch OFF, then press the "OK" button to send the new barcode(s) to the ECM.
1. After INSITE™ electronic service tool reconnects with the ECM, verify that the "Change Status" = "Success".
If "Change Status" = "Error Occurred", "Invalid Barcode", Invalid Cylinder Number", or "Duplicate Barcode", check for the following:
• Verify the correct injector trim code was recorded from the injector.
• Re-enter the trim codes.
Clear all inactive faults.


Connect the actuator harness to each of the six injector solenoids.
Torque Value: 2 n.m [18 in-lb]
NOTE: Install the injector wires so they will not interfere with a rocker lever or engine brake housing. If the rocker lever is able to come into contact with the injector harness, it will rub through the wire insulation and cause injector circuit fault codes.
If applicable, connect the actuator harness to the engine brake solenoids.
Torque Value: 1.5 n.m [13 in-lb]
nstall the seven captive Allen screws securing the internal actuator harness to the rocker lever housing.
Torque Value: 9 n.m [80 in-lb]


Tighten the pump-to-rail supply line at the pump and fuel rail (1).
Tighten the injector supply line nut(s) at the fuel connector(s) (2).
Tighten the injector supply line nuts(s) at the fuel rail (3).
Torque Value: 47 n.m [35 ft-lb]
Tighten the pump to rail supply line clamps (4).
Torque Value: 47 n.m [35 ft-lb]

Mr. Hagg, you sir are a Godsend. Within a half hour of getting to work this morning I have the injector out. Amazing how good information helps! I award you 200 interweb points!
