How to remove fuel injectors?
Replacing a fuel injector seems like a daunting project, but with a little skill, you can get the job done yourself and save a lot of money. Stores charge a great deal of fuel injection labour. If you know you have a faulty injector, the work can be done at home.
Before starting to replace the fuel injector or fuel rail, you need to consider safety. When using fuel, always keep fire safety in mind. You also need to make sure you wear goggles. Even if you have relieved the pressure in the fuel injection system, when you start to disconnect the high-pressure line and remove the injector, some fuel will still be scattered.
How to change fuel injectors
- Disconnect car electrical connector
- Remove Car fuel rail mounting bolts
- Lift rail from the intake manifold
- Remove fuel injector retainer clip
- Run the injector from the fuel rail (fuel will be present)
- Fit the new injector to the old unit
- Insert new injector using new O ring seals (lube with engine oil)
- Reinstall the injector rail and mounting bolts

How much does it cost to replace the fuel injector?
The costs of replacing fuel injectors may vary depending on the location and configuration of the fuel injection system, i.e. direct injection, throttle body or injection port. Generally, fuel injectors cost from $ 50.00 to $ 100.00 each, manpower will vary.
If your car is equipped with fuel rails
Many vehicles equipped with fuel rails can be equipped with a safety valve (often in the form of a Schrader valve) or a screw that can be loosened to release residual pressure. If the safety valve does not exist or cannot be located, another method is to locate the fuel pump fuse or switch and then start the engine. With the engine running, remove this fuse. Now, when the fuel pump is no longer active, the engine will continue to draw fuel from the pipes before stalling.
