Need more specifics.
1. If the engine doesn't crank, check the battery, starter, ignition switch, all associated wiring, and make sure it is in park (you may have a bent shifter linkage that isn't taking the transmission fully out of gear).
2. If it does crank, check that you are getting fuel by depressing the schrader valve on the fuel rail. No fuel-- check that your tank isn't empty, your fuel pump, fuel pump relay, inertia switch, and all associated wiring.
3. If you have fuel-- check for spark at the plugs. No spark--check coil, ignition control module, Throttle Position Sensor, Crank Position Sensor, Camshaft Position Sensor, Spark Plug Wires, and all associated wiring.
4. If you have spark to the plugs, pull the spark plugs out and check the electrodes. If they are good, perform a compression test on the engine and check to make sure the timing belt is intact.
