Fuel Injector Replacement

How are fuel injector issues diagnosed?

If fuel delivery system symptoms are present, the technician will first conduct a visual inspection. If the issue isn't clear after a physical inspection, the technician will connect a computerized scanner to the vehicle to read some of its sensors. If there's a fuel injector problem, the technician would most likely find that misfires are happening frequently on one cylinder. The fuel injector or injectors in question must be tested, and may require removal for bench testing. Any failed components must be replaced, and the vehicle will be checked to ensure the problem is fixed.

How is a fuel injector replaced?

Typically, the intake manifold must be removed to access and replace the fuel injectors. This can be a large job that may involve draining the coolant and oil, removing many engine components, and replacing the intake manifold gasket. Some cars, though, are designed with plastic intake manifolds that do not have oil or coolant passages, making this process easier. Once access is available, the fuel injector is disconnected from the fuel rail and electrical connector and removed. The new one is then installed in its place.

RepairPal recommendations for fuel injector issues

When replacing fuel injectors, use high-quality, OEM parts. Keeping the injectors the same will ensure even power across the engine and a proper air-fuel mixture for all cylinders. This should result in smooth running.

What to look out for when dealing with fuel injector issues

When working with fuel, the battery should always be disconnected, and proper precautions taken against fire.

Can I replace the fuel injector myself?

This is not a DIY job. Fuel injector replacement should be left to a professional. The risk of fire is enough by itself, but this repair can also get very complicated. A good amount of knowledge goes into removing the injectors, intake manifold, fuel rail and other components, and if done wrong, it can further damage the vehicle.
