Car try's to start but won't, turns over but won't start! Why ?

Maybe timing belt is broken

As you were advised: A failed timing belt is a good possibility, does it seem to be cranking over with a different sound ? like it is cranking too fast ?, if so, your Toyota has what is called an interference engine, which means when the timing belt fails, a high possibility of internal damage has resulted, co$ting several hundred dollars to repair. Of, course, other issues may be: failed fuel pump, failed fuel pump relay, failed ignition system component, wiring, or some other electrical or computer issue. The timing belt is one of the most overlooked, but very important, maintenance items which will bite the owner if not replaced in a timely manner.
