hi all this will probably get deleted but i have searched the common probs but still no wiser!! Have a 97 16 v and went to start it no go, no sark at plug no spark from coil pack king lead when i earthed it on the head so changed coil pack for a new one still wont start.Kneed to know how to test for power going to coil pack with test light ie what wire on coil pack pug and when should this be getting power? then what next if power there or not.Changed to crankshaft sensor about 18 months ago could this be the culprit do they just go like that and would this stop coil from firing please help!!!
