DO NOT TRY IT BLINDLY VERY BAD ADVICE FROM ABOVE
You do not need to earth the coil pack itself in any way.

Is it not worth pulling a plug out to and turning over to see if you have spark?

Good point .............and Roosie - make sure the phase sensor connector (plug) is still in place (connected).

If it has become unplugged, then you also need to ensure that it is re plugged in the correct way round - it will fit both way rounds! If it is plugged in the wrong way round then the engine wont start at all (much like your symptoms!)

you forgot to take out the supressor in the green wire as mentioned
This can cause fatal damage to the coilpack driver
