How do you change the injector on a Peugeot 206?

Answer 1

This is how I did it

Make the vehicle safe.

Remove.

Unplug the three quick release connections to the air intake pipe and rocker box (hard plastic pipe) and move rearward out of the way. Slacken off the two pipe clips holding the plastic 90 degree intake pipe and remove. Unplug the coil pack connector (grey plug on ours) in the middle of the top of the coil pack and move out of the way. Remove the two 6mm studs or nuts from either end of the coil pack. 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 cable nipple from air butterfly actuator. Remove small plastic cable support and move cable out of the way. Remove the central steel cable support (Three torx screws)

NO SMOKING

With the fuel rail still secure, remove fuel supply pipe by depressing the quick release buttons (both sides) and easing the pipe off of its spigot. (Will be a snug fit, don't snap the spigot) As it is removed, petrol will spray out as the seal is broken until the system pressure is depleted. Remove the two torx screws securing the fuel rail and the central 6mm nut holding the small steadying bracket. The other end of this small bracket is slotted so the awkward 6mm nut below securing the other end needs only slackening off. Remove the four spring clips between the fuel rail and injectors. Be careful not to bend these too much if replacements are not available. Firmly, wiggle and lift the fuel rail off the top of the injectors. (do not be tempted to get the crow bar out) Some injectors may stay in the head although some may come away with the rail. These can be separated before the rail is fully removed. With the rail removed, unplug the injector electrical connection and remove the injector/s. Ensure all "O" rings and wire spring clips are accounted for..

Replace

With suitable lubricant on all "O" rings. Insert the injector firmly into its respective port. After checking the spring clip is suitable for use and in its correct position on the plug, remake the plug connection between the loom and the injector. A definite click should be heard when the spring clips snaps home.

Fit the undistorted clips in the correct orientation at the top of the injectors. Slide the fuel rail down on top of the lubricated "O" rings until the clips snap into place on the fuel rail flanges. Secure the central bracket, two torx screws and fuel pipe. Replace throttle cable in reverse order of dismantling and ensure adjustment is correct. Replace coil pack, connetors and other items in reverse order of removal. It may be a good idea to ensure any spilt fuel is not around for start up although by this time, it should all have evaporated.

Start up and check for leaks.

Took me about an hour at a lazy pace including a cup of tea.
