Instrucțiuni de montaj
- [
- {
- "step": 1,
- "title": "Depressurize D-4S Fuel System & Safe Disassembly",
- "instruction": "Disconnect battery ground cable. Depressurize high-pressure fuel lines by removing fuel pump fuse and cranking engine, or draining residual pressure through diagnostic port into safety container."
- },
- {
- "step": 2,
- "title": "Engine Cover, V8 Intake Duct & Sound Insulator Removal",
- "instruction": "Remove engine V8 appearance cover and intake air resonance ducting. Detach sound deadening foam insulating blocks enclosing the Bank 1 / Bank 2 high-pressure pump housings."
- },
- {
- "step": 3,
- "title": "High-Pressure Pipe & Low-Pressure Feed Disconnection",
- "instruction": "Disconnect electrical connector for the spill control solenoid. Using a line wrench, loosen high-pressure fuel outlet union nut (30 N·m). Release low-pressure supply rubber hose quick-connect clip."
- },
- {
- "step": 4,
- "title": "Camshaft Position Verification & Old Pump Extraction",
- "instruction": "Rotate engine crankshaft until the camshaft drive lobe is at base circle (lowest lift) to prevent excessive spring tension during unbolting. Loosen the two flange mounting bolts evenly and remove old pump."
- },
- {
- "step": 5,
- "title": "Roller Tappet Inspection & New Pump Installation",
- "instruction": "Inspect roller tappet in the cylinder head for scoring, pitting or flat spots. Coat new O-ring with clean engine oil. Insert Denso pump and torque mounting flange bolts progressively to 21 N·m."
- },
- {
- "step": 6,
- "title": "Fuel Line Torquing, Priming & Oil Dilution Check",
- "instruction": "Align high-pressure steel tube squarely and torque union nut to 30 N·m. Reconnect harness. Prime ignition to pressurize system, perform soapy water leak check, and verify engine oil dipstick for absence of gasoline smell."

Coduri de Eroare (DTC) si Protocoale de Diagnostic
Coduri comune de eroare de diagnosticare (DTC) declansate atunci cand acest injector common rail sufera uzura, defectiuni de circuit sau abateri:
P0087Critical
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
P0201 - P0208High
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.
P0300 / P0301+High
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
P0088High
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
