Fuel Injection System Repairs: How To Remove Your Fuel Injector

The fuel injector is an important part of your fuel injection system, which helps to carry fuel to your engine. This type of part includes a valve and nozzle for spraying the fuel into the combustion chamber of your engine. If it is failing, you might need to remove it and make room for a new one. Here are instructions for removing it so you can replace it with a new one.

Get Prepared

Before you do any type of automotive repair, you should take some time to prepare. Dealing with the fuel injection system of your vehicle can be dangerous, so make sure safety is your top priority. Protect your eyes from any spraying oil by wearing a pair of goggles. It is also a good idea to wear gloves. If the gloves fit you well, it won't be difficult working with the fuel injector while wearing them.

Also make sure to organize your plan of attack beforehand by inspecting the fuel injection system. Additionally, have a variety of auto repair tools on hand, including a fuel injector puller if you can get one.

Remove the Fuel Rail

The first step to removing the fuel injector is to remove the fuel rail. This must be disconnected in order to access the fuel injectors. Look for the fuel rail under the hood, then follow it to the end to find the primary fuel line. You need to disconnect the fuel line before you continue. Also check the other end of the fuel rail to see if there is another line, as some vehicles have more than one.

Take a moment to check if there is wiring traveling on top of the fuel rail, as it will need to be disconnected first. You will need a screwdriver to remove screws or bolts that are keeping the fuel rail in place. Unscrew any screws or bolts you find and disconnect wiring if needed. Once that has all been removed, you can pull the fuel rail from its position near the fuel injectors. It should be easy to remove from the injector tops.

Remove the Fuel Injectors

With the fuel rail removed, you can disconnect the fuel injector. When you find the fuel injector, you will notice that it has a plug at the top, or on the side near the top of the injector. The plug is what connects the wiring harness to it. They usually have a springy-type wire holding them in place. All you need to do is place a flathead screwdriver between the plug and the spring and pry it away. Do so carefully so you don't damage anything. Remove it slowly, making sure the spring doesn't get away from you. Set it aside where it won't get lost.

Before pulling out the fuel injector, remember that it is in a sensitive place near the engine. If you yank it too hard, you could cause damage to the engine's other mechanisms. A fuel injector puller is the best tool you can use for this job. If you have access to this tool, you just need to put it under where the injector housing is, then pull out the injector.
