What is a common rail injector?

Common rail direct fuel injection is a direct fuel injection system for diesel engines. It features a high-pressure (over 2,000 bar or 200 MPa or 29,000 psi) fuel rail feeding solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles).

How often should diesel injectors be replaced?

Diesel fuel injectors generally have a shorter lifespan than their predecessors, meaning they need to be replaced more frequently for optimal performance. The life expectancy of a good quality diesel fuel injector is around 150,000 kilometres. They should be checked out by a professional at around this time.

When should injectors be replaced?

We recommend cleaning fuel injectors at least every 36 months or 45,000 miles. Consider it a tune up for your fuel system- it's really amazing the difference people experience after having a fuel injection and throttle body cleaning on a car that has gone more than 60,000 miles without those services.

How do you test a fuel injector?

To test fuel injectors, start by popping your car's hood while the engine is running. Place a thin metal rod or screwdriver on one of the injectors and lean your ear close to listen for an audible clicking sound, which indicates the fuel injector is functioning. Test each fuel injector in your vehicle the same way.

What causes a fuel injector to stick open?

If the coils short, this will cause misfires with a malfunctioning control plunger impacting when fuel is injected into the engine chamber. If debris gets caught in the wrong place, it can cause the injector to be stuck open, which could cause significant long term to the engine.
