LOL

When cranking im getting a spark between the starter and the chassis 4" gap, it only happend once?

Now i know 12v wont do that so its from somewhere else like coilpack etc. any ideas as to why? or has anyone ever had this?

12v will do that, check the starter wiring is all tight and check the live is not shorting there too.

The OP is correct,12 volts WON'T do that as the insulation of air doesn't start to break down until we get to between 2000 and 3000 volts[li].

Are you sure it is actually arcing across as you've got individual coiplacks,so there's no HT floating around the engine bay like there is in mine? Even if it was ignition coil HT I doubt very much if it could even to ground across more than about a one inch gap.
