my car dying for no reason and won't start back for hour what could be the prob?

I would suggest to find out why the Check Engine light is on. If you need a shop to diagnose this for you please visit this link to find a Certified Shop near you - http://repairpal.com/hyundai-within-10-miles-of-versailles-kentucky-40383

Looks like you have been guessing at the problem and just throwing parts at it trying to fix it .. I didn't see anything about the *crankshaft position sensor* posted as one of the replacement parts .. You might as well throw one of those at it also as that is the most likely suspect! .... I agree with the other answer, testing BEFORE parts replacement is always the best route to take... However it seems you are determined to do this your way... Good luck with it!
