Any tips? Thanks

Re: Injector pump removal.
This might help you understand the removal procedure a wee bit better.
1. using 10mm and 12mm remove the inlet manifold/egr elbow
2. 1f your car is old shape remove the vacuum valve block, 2x 12mm, undo the plugs/piping from valves and fuel pump,pull if up slightly and bend it forward, it puts slight curve in the metal pips than run down and allow it to all slide out, if you have a new shape, ignore all that.
3.8mm nuts to remove fuel line clamps, 17mm x4 at each end to remove the fuel lines, i do the fuel pump end first.
4.can be done without removing metal centre plate but it doe make it easier if its out, from drivers side pull out the lower small console panel, theres a 12mm bolt there, also remove the 2 holding gear selector in place, disconnect all electrics and remove all 10mm bolts (about 8 iirc), leave the handbrake in place, lift the whole panel and stand/rest in on the folded back seats.
5.with the panel out you can get at the 10mm bolts holding cam cover in place, 2 from passenger side, the rest from drivers side, the lowest inside is a bit of a pain, then wiggle the cam cover off and out of the way.
6.the pump is held in place by 2 x 12mm nuts and 1 x 12mm bolt, the 2 at the front and a plate at the back,undo and leave them with lots of slack.
7. using a big socket 38mm, to lock the crank in place, use a 19mm socket to undo the nut in the middle of the lower/fuel pump pulley, there is a copper washer behind the nut.
8.if you have a puller/pusher then undo a pair of bolts on the pulley and use them to puse the pump out, if not, pull the carpet out and you'll see a hole covered with tape,in front/above the pulley, the pump shaft has an inversion in it so using a long pin punch, give it a couple of sharp hits and the pump will release from the taper,but be held in place by the 12mm nuts/bolts.
9.undo all remaining plugs, be aware that the rev counter wiring runs straight past the pump, undo the last 12mm and the pump should come out in your hand.

Re: Injector pump removal.
Great post teenmal - should be got into a fact sheet. Is there any requirement to mark\scribe pump position before removal to ensure its put back so timing is ok? I'm no techie so just asking as I seem to recall reading about pump timing issues.
Re: Injector pump removal.
Many thanks teenmal,excellent instruction.
I wasn't hitting the shaft hard enough.
Out now.
Thanks again,
Adam.
