- {
- "step": 1,
- "title": "Depressurize Fuel Rail & Remove Intake Manifold",
- "instruction": "Depressurize high-pressure fuel rail via diagnostic scan tool or fuse pull. Remove upper intake manifold to access high pressure fuel rail assembly."
- },
- {
- "step": 2,
- "title": "Extract Fuel Rail & Remove Injectors",
- "instruction": "Unbolt fuel rail holding bolts (9 N·m). Use slide hammer puller T10133/1 to gently extract fuel injectors from cylinder head combustion chambers."
- },
- {
- "step": 3,
- "title": "Calibrate New Teflon Combustion Chamber Seal",
- "instruction": "Cut and remove old combustion seal without scratching injector groove. Install new Teflon ring using expansion cone T10133/2 and compress with sizing collar T10133/3."
- },
- {
- "step": 4,
- "title": "Seat Injectors & Torque Rail Bolts",
- "instruction": "Push injectors into cylinder head bores by hand. Torque rail retaining bolts evenly to 9 N·m. Torque high-pressure pipe union nut to 27 N·m."

Diagnostic Trouble Codes & Fault Protocols
Common diagnostic trouble codes (DTCs) triggered when this common rail injector experiences wear, circuit faults, or calibration drift:
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
Injector Circuit Malfunction / Open Circuit
Solenoid coil resistance drift (0.2-0.5 Ω) or piezo stack degradation triggers driver stage shutdown on affected cylinders.
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
