- "step": 1,
- "title": "EcoBoost High-Pressure Fuel Rail Depressurization",
- "instruction": "Depressurize fuel system by removing the low-pressure fuel pump fuse and running engine until it dies. Disconnect negative battery cable."
- },
- {
- "step": 2,
- "title": "Upper Intake Manifold & Charge Pipes Removal",
- "instruction": "Disconnect turbo boost pipes, throttle body wiring, PCV hoses, and remove the composite upper intake plenum to access Bank 1 and Bank 2 fuel rails."
- },
- {
- "step": 3,
- "title": "High-Pressure Crossover Pipe Disconnection",
- "instruction": "Unscrew the stainless steel high-pressure fuel crossover lines using a 17mm flare nut wrench. Discard the single-use hard pipes per Ford service directives."

- {
- "step": 5,
- "title": "Injector Installation & Final Torquing",
- "instruction": "Lubricate upper O-rings with clean engine oil (keep Teflon tips completely dry). Push injectors into rail, torque rail bolts to 10 N·m (89 in-lb), and crossover pipe nuts to 28 N·m (21 lb-ft)."

Codes de Defaut (DTC) & Protocoles de Diagnostic
Codes de defaut diagnostiques (DTC) courants déclenchés lorsque cet injecteur common rail subit une usure, des pannes de circuit ou une dérive d'étalonnage:
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.
