Replacing Fuel Injectors: A Step-By-Step Guide For Peugeot 206 Owners

how to change fuel injectors on peugeot 206

Changing the fuel injector on a Peugeot 206 is a complex process that requires careful attention to detail. It is important to make the vehicle safe before beginning any work. This includes unplugging the air intake pipe and rocker box, removing the coil pack connector, and disconnecting the throttle cable. The fuel rail must then be removed by depressing the quick-release buttons and unsecuring the torx screws and central nut. With the fuel rail removed, the injector can be unplugged and removed, taking care to account for all O rings and wire spring clips. The new injector can then be inserted, taking care to lubricate all O rings and ensure the electrical connections are secure. The fuel rail can then be replaced, followed by the throttle cable and other components. Finally, it is important to start up the vehicle and check for any leaks.

Make the vehicle safe

To make your Peugeot 206 safe to work on, start by unplugging the three quick-release connections to the air intake pipe and rocker box (hard plastic pipe) and move them rearward out of the way. Next, slacken the two pipe clips holding the plastic 90-degree intake pipe and remove it. Now, unplug the coil pack connector (grey plug) in the middle of the top of the coil pack and move it out of the way.

Remove the two 6mm studs or nuts from either end of the coil pack, then lift and remove the coil pack. Remove the throttle cable from the main cable steady/adjuster by first pulling the large long spring clip to provide enough slack to remove the cable nipple from the air butterfly actuator. Remove the small plastic cable support and move the cable out of the way. Finally, remove the central steel cable support (three torx screws).

Disconnect the air intake pipe and rocker box

To disconnect the air intake pipe and rocker box on a Peugeot 206, start by making the vehicle safe. Then, unplug the three quick-release connections to the air intake pipe and rocker box. These are hard plastic pipes. Move them rearward and out of the way. Next, slacken the two pipe clips that are holding the plastic 90-degree intake pipe and remove it.

The air intake pipe is responsible for supplying the engine with air, which mixes with fuel in the combustion chamber. The rocker box, on the other hand, houses the valve train, including the rocker arms and pushrods, which are essential for opening and closing the engine valves during the combustion process.

By disconnecting these components, you will gain access to the fuel injectors and other related parts, allowing for their replacement or maintenance.

It is important to note that working on fuel injectors can be a complex task, and it is always recommended to have a qualified mechanic perform any repairs or maintenance to ensure the work is done correctly and safely.

Disconnect the coil pack connector and remove it

Disconnecting and removing the coil pack connector is a crucial step in changing the fuel injectors on a Peugeot 206. Here is a detailed guide on how to do it:

First, locate the coil pack connector. It is usually a grey plug found in the middle of the top of the coil pack. Once located, unplug the connector by firmly pulling it straight out. Be careful not to bend or damage the connector. If it is difficult to remove, you can gently wiggle it back and forth while pulling to loosen it.

After disconnecting the coil pack connector, move it out of the way to avoid any accidental damage during the rest of the fuel injector replacement process. Now, you can proceed to remove the coil pack itself. To do this, remove the two 6mm studs or nuts from either end of the coil pack. You may need to use a suitable wrench or socket to loosen and remove them. Once the studs or nuts are removed, carefully lift and remove the coil pack from the engine bay.

It is important to place the disconnected coil pack connector and the removed coil pack in a safe location, away from any flammable materials or sources of ignition. Additionally, make sure to handle the coil pack with care as it is an essential component of your Peugeot 206's ignition system.

By following these steps, you will successfully disconnect and remove the coil pack connector, allowing you to proceed with the next steps in changing the fuel injectors on your Peugeot 206.

Remove the throttle cable

To remove the throttle cable from a Peugeot 206, you will need to first remove the large long spring clip. This will provide enough slack to remove the cable nipple from the air butterfly actuator. Once the spring clip has been removed, you can then proceed to remove the cable nipple.

Next, you will need to remove the small plastic cable support. This will allow you to move the cable out of the way. At this point, you should also remove the central steel cable support, which is held in place by three Torx screws.

It is important to note that when removing the throttle cable, you should be careful not to lose any small parts such as screws or clips. Keep them organized and easily accessible for when you need to reinstall the throttle cable.

Additionally, it is always recommended to refer to the vehicle's repair manual or seek the assistance of a qualified mechanic if you are unsure about any part of the process.

Remove the fuel supply pipe

Before beginning any work on the fuel system, it is crucial to relieve the fuel system pressure and disconnect the negative battery cable to ensure your safety and avoid any potential hazards. Make sure you have the necessary tools and a suitable workspace.

Locating the Fuel Supply Pipe: The fuel supply pipe is connected to the fuel injector rail, which sits on top of the engine. It is a metal pipe that carries fuel from the fuel pump to the injectors. To access it, you may need to remove any covers or components that obstruct your view and access, such as the air filter housing or any engine covers. Identify the fuel supply pipe and follow it from the fuel rail back towards the fuel pump to familiarize yourself with its routing.

Removing the Fuel Supply Pipe: Start by locating the clamp or clip that secures the fuel supply pipe to the fuel injector rail. Depending on your Peugeot 206's specific model and year, the clamp design may vary. You may need a specialized tool to release the clamp without damaging it. Once the clamp is released, gently lift and wiggle the fuel supply pipe to detach it from the fuel rail. Be careful not to force it, as there may be residual fuel pressure. Have a rag or container ready to catch any residual fuel that may spill.

Once the fuel supply pipe is free from the fuel rail, carefully twist and maneuver it to remove it from the engine bay. Take note of its routing and any clips or guides that hold it in place. You may need to loosen or remove these clips to fully remove the pipe. Again, be cautious of any residual fuel and have a suitable container or rag to catch any drips. With the fuel supply pipe removed, you can now access the fuel injectors for replacement.

Remember to work safely and carefully when dealing with the fuel system. Always refer to your Peugeot 206's repair manual for specific instructions and torque specifications if needed.
