You are either reading/measuring wrong or the coil is shorted if you are seeing 12v at the spark plug lead. I can't help but think the problem HAS to be related to the work you done on the fuel system.....You'd be really unlucky to have something else fail at the same time. Check that you have 12v on the orange wire at the reverse polarity relay. It's possible that this supplies the haltech with power which then feeds the CAS.

How'd you go with this??

Also keen to kno if got it running again

not as of yet i have fixed the problem with fuel always primeing,but as for the spark im re going over evrything to see if im getting fuel and all the rest of all that stuff fuel is coming out of hose,but i cleaned all the spark plugs but now even though i kicking it over it doesnt seem to be fouling up, so my next question is,if fuel is not going into througb injectors would that tell ecu not to spark? ---------- Post added 27-04-12 at 21:16 ---------- if i cant get it goin in a week i will probly call a auto electrician to come have a look

Fuel system has no influence on spark. Cas is the main reference for everything in the ecu. If you've got no signals from the cas, then this is your problem. Do you have 12v on the orange/black wire at the cas?
