Does the engine turn over? If not, check the power to the starter and the solenoid.
If yes, check for spark. Use a test light to see if the injectors are being pulsed.

Ok. If the engine is running, why would you be turning the key? Turning the key will either shut the engine off or engage the starter (which could cause the engine to shut off).
