with out knowing if you can crank but not start, or if you just get a click, if you can crank the car but not start i would see if you have spark.... they sell spark plug like devices for this at auto stores, if you have spark but still no start, remove a spark plug and smell... do you smell gas, do you have fuel, did you purchace e-85? when was the last time you had a timing belt replaced, is the check engine light on? i need more info to direct you to the problem... please reply with more data
