Injector Failure Symptoms
Most injector failures announce themselves long before the engine stops: a single-cylinder knock that fades as the engine warms, white smoke on cold start, diesel dilution in the oil, or a hesitation under load. This category catalogues the symptom patterns by failure mode — nozzle wear, solenoid degradation, piezo stack failure and back-leakage — so you can match what a vehicle is doing to what is actually wrong.
