Symptoms Of A Failing Injector
Common signs an injector may be failing include rough idle, misfires, increased fuel consumption, black smoke from the exhaust, difficulty starting and check engine light fault codes related to fuel delivery. Electrical faults, clogged nozzles or internal leaks can cause these symptoms.
Common Causes And Life Expectancy
Injectors wear or fail due to contaminated fuel, carbon build-up, prolonged idling, poor maintenance, or electrical connector problems. Lifespan varies with usage and maintenance, but replacement is often required after high mileage or if specific faults are diagnosed.
Replacement And Installation Guidance
- Safety First: Disconnect the battery and relieve fuel system pressure before starting work.
- Access: Remove engine covers and intake components to reach the common rail and injectors.
- Disconnect: Unplug the injector electrical connector and remove the fuel rail mounting bolts.
- Remove Injector: Carefully extract the injector, noting sealing washers and O-rings. Replace seals with new parts to ensure proper sealing.
- Install New Injector: Lightly lubricate new O-rings with clean engine oil or manufacturer-recommended lubricant, seat the injector and reassemble the rail and connectors.
- Prime And Test: Reconnect the battery, prime the fuel system to remove air, start the engine and check for leaks and correct operation. Clear any diagnostic codes if required.
If unsure, have a qualified technician perform the replacement to ensure correct sealing and calibration. Always verify compatibility by engine code or part number before fitting.
