What would make my engine not start,it quit and hasn't started since

Loss of spark, timing belt, ect........ need to.check those basic areas first before getting too deep. Make sure you don't have a factory alarm shutting things down.

First, it would be good to verify that in fact, there is no spark. In this case, make sure the timing belt did not brake or jump a tooth. But one of the most common issue with this vehicle is the ignition distributor. Always remember that (before replacing a part) an inspection for the correct power and signals has to be made, this way you just don't replace parts to just replace parts.
