Excellent diagram thanks JesseT thats made things much clearer. There is DEFINATELY no spark, I have one of the plugs resting against the head visible at all times. I now know why I had power to the middle pin of the coil, because its obviously the wire that goes to pin #8 on the EDIS so thats ok. I am sure that the rev counter was moving on crankover, I will double check this (I'm hoping it does as I have put a brand new CPS in). If the rev counter moves AND I have power to the coil pack and module (through pin #8) do you think this indicates that the EDIS module is probably the faulty link by not supplying a signal to the coil pack?
We appear to be getting closer to the problem!

UPDATE: Been over this afternoon, yes the rev counter does flick when the engine is being turned over
