Re: car wont start
check for spark. im assuming you should be getting spark because you replaced everything without checking everything and probably wasted a whole lot of money. did the car jerk when it shut off? or just shut off? are you throwing a check engine light?
single cams are notorious for having distributors shit out on them, but since you replaced that i would recommend taking the valve cover off and the upper timing belt cover to make sure that your timing belt did not snap.
