Depends on what is wrong with it. The injectors can be replaced or resealed with a new O-ring. How to know if injectors are bad? How often should fuel injectors be replaced?
How do you repair a fuel injector? Keep your engine running smoothly by cleaning your fuel injectors about once a year.
Fuel injector cleaning kits are simple to use and very. Luckily injector rebuild kits are readily available, are. Although fuel injectors have evolved and become very reliable, it’s still possible for one to fail. A fuel injector is not a maintenance item, so there is no specific interval for inspection or replacement.
If you suspect a faulty fuel injector, it’s best to have a complete diagnosis performed at a repair shop. The fuel injector is an electronically controlled valve that is supplied with pressurized fuel by the fuel pump and when energized atomizes the fuel into a fine mist. Furthermore, New technology has made fuel injectors more precise than ever in dispensing fuel.
If the fuel injectors are not operating properly, then other parts of the engine will be affected as well. Lift the fuel rail off of the intake manifol bringing the injectors with it.
This takes a good amount of force, as the injectors are attached to the rail, and the sprayer tips are a snug fit in the intake manifold. On average, fuel injectors tend to fail after 80miles, and require little maintenance. To prolong the life of the fuel injectors , follow the scheduled maintenance schedule for cleaning the fuel delivery system and injectors. A bad fuel injector will wreak havoc with how your engine runs, and will likely leave you stranded on the side of the road. In a bid to reduce exhaust.

If an externally-leaking injector is suspecte do not start your car due to the fire hazard.

Remove any parts that may hinder access to the injectors.
Leaking fuel injector can be cause of hard starting. This is because the fuel rail pressure has dropped and fuel has leaked into the manifold and causes the spark plugs to become flooded. Shop for a replacement fuel injector at AutoZone, where you can find a variety of vehicle-specific injectors. Common Rail injectors are becoming increasingly popular as they improve fuel economy and minimize emissions.
They are more advance but complex compared to other types of diesel fuel injectors , and require a different testing process. Our equipment provides us the most efficient and precise way to examine modern-high-pressure fuel components.
