Hi Martin.
Clamp the injector into the vice, and use a ring spanner to crack the cap cover, first clean any dirt around the top, with a nylon or brass wire brush.

1

Crack the cover 15mm ring spanner, they are quite tight, once cracked undo a little then tighten it back down with your fingers, once again clean any dirt that as risen from opening the cover, repeat this until all dirt and been cleaned.
2

keep you finger on top the the tip while doing this procedure.

as you lift the cover hold down the tip.
7

Now slowly remove the tip take great care as there are two little locating pins, and and a centre shim.
8

Do not lose any of those.
9

Place the tip on a clean piece of paper with the cover, note the centre pin.

You need to tap this centre pin out by just knock the edge of the body on the paper which should be on an hard surface, once it starts to come out you can grip it and pull it out fully.

Spray them with carb cleaner and wipe clean.

Then with the body in your hands spray carb cleaner through the centre so you can see the spray come out of the tip in a 5 hole spray pattern

Clean inside the cover with carb cleaner and a rag refit the pin in to the tip, make sure its free to move, you can dip it into some diesel if you like.

Re-fit in reverse of taking apart, this is the simplest way of cleaning the tips, you will now know that the spray pattern is equal.

If the injector is leaking internally due to a shim or tiny o-ring then you would need to do a full strip down which is time consuming and you need a sonic cleaner.

Once you have cleaned all the tips add new copper washers and refit to the same place they came from in the engine.

Hopefully there is no leak back and the car starts better.
