Ive had the exact same prob with my car, sometimes cranking over with out it sparking and after changing the coil pack, dist, new plugs n leads, a week in a garage (all this after the car having to be towed 300miles!) i tried the transponder / imobiliser trick and it seems to have worked......Thanks so much for everyones concerted efforts
