Tell us more. Is it turning over but not starting? Can it start up cold, but not when hot? Try this: Turn the ignition switch to on and off three times in succession, and on the 4th time then to start and see if it runs then. If it runs, then that usually means the system is not holding pressure. Watch the rpm gauge, if it is not moving when cranking that usually means a bad crankshaft position sensor. If you own a scangauge you can use that to monitor fuel pressure. Other thing that will give you a no start are bad fuel pump or clogged fuel pump sock. A bad IAC(idle air control valve), bad fuel pressure regulator, leaking fuel injector, and a bad or stuck non return valve.
