    Hi!,
    Sorry to hear that you are still having probs. Try here for some answers

    Pictures speak louder than words. You will need a multimeter to do some of the checks, but its less frustrating. Basically it is a process of elimination. Other than that you are going to have to learn how to pull the diagnostic codes from the ecu.
    Not sure what fuse you are talking about, but clearly any electrical component should be functioning. Would be worth checking for voltage at various sensors, most importantly the ecu itself.
    Was the car working before you changed the dizzy? If so, it can only be something you have touched to fix it. It would be worth checking something as simple as a fuse. The simple things are often overlooked!
    Good Luck!

          Good picture (no.2) Thats how it should be. It might be worth removing the immo to make sure that it isnt anything to do with that.

            Got it running now. Runs by itself, starts ok but very very lumpy. Almost sounds like a misfire and seems to be running very rich. A sensor on top of the im is broken. Any ideas why?
            Thanks

                      So would that make it run lumpy? ( I love these technical terms)

                          Basicaly ive turned it to where the car will start and run, which must be the correct position for it as it wont start at any onther orientation, i dont have much skin left on my hands!

                            Well done!
                            Not very scientific, but hell, it works!
                            So basically you didn't quite get the alignment right. Not surprising due to the marks located all over the engine.

                              Double check the HT lead positions
                              Remove spakplugplug and see if one or more is wet
                              Double check the HT lead positions
                              Remove injector plugs one by one when engine idling and listen if it makes a difference
                              Double check the HT lead positions
