- Cylinder Cut-out Test: Using diagnostic software (ET), shut off cylinders one by one and observe engine speed fluctuations
- Fuel Rail Pressure Test: Check for internal leaks preventing system from building critical starting pressure
- Back-leakage Test: Excessive back-leakage indicates severe wear of internal control valve assembly
- Visual Inspection: Inspect fuel injector nozzles for carbon buildup, blockage, or corrosion
- Preparation: Clean the injector bores thoroughly. Ensure no carbon debris, old O-rings, or fuel/oil residue at the bottom of the seat. Inspect the injector sleeve for pitting or erosion.
- Lubrication: Apply clean engine oil to the three O-rings and backup rings. Never use grease - only clean engine oil ensures seals slide in without tearing.
- Seating the Injector: Push the injector down firmly by hand until you feel it "seat." Install the hold-down clamp and bolt.
- Torque Specifications: Tighten the bolt to 30 N⋅m±7 N⋅m (22 lb-ft). Note: Over-tightening can crack the injector body; under-tightening causes combustion gas leakage.
- Trim Code Programming: Locate the 6-digit alphanumeric code on the top of the injector solenoid. Use ET (Electronic Technician) software to program this code into the ECM for precise fuel delivery synchronization.
| Issue | Root Cause | Solution |
|---|---|---|
| Black Smoke | Poor spray atomization or stuck needle valve causing dripping | Inspect the air filter |
| Hard Start | Internal leakage in injector leading to insufficient starting oil pressure | Inspect injector O-rings and internal seals |
| Engine Misfire | Faulty solenoid valve coil or worn internal valve components | Inspect wiring harness connections and replace damaged injectors |
