Peter lucas, are you still out there??
Ive just read your post on starting problems and ive had the same problem as you, even a broken rotor arm. (not sure about yellow spark)
I was wondering how you have got on with it. Did you manage to get it sorted??
Ive read a few theads about swapping the phase sensor wires around and some seem to contradict the others!!!
I tried it and still no joy, i also changed the CPS.
Im now missing a spark on number 2, dont know why yet. They are new plugs but this one isnt "fouled up " from starting
Anyway let me know how you got on, it couild help with my problems.
Cheers bud.
Muffster.
