1. Crankshaft Position Sensor (CPS) Failure
The sensor degrades or fails electrically, typically due to age or contamination.
2. Fuel Injector and Fuel Rail Pressure Issues
Fuel contamination (from infrequent diesel filter changes or poor-quality fuel) causes micro-debris to lodge in the suction control valve or injector internals, reducing fuel rail pressure and causing engine performance faults[2].
