first thing you have to do is narrow down the possibilities. Fuel, Starter, or Spark.
Get a can of carb cleaner, engine igniter fluid, etc, some kind of flammable engine cleaning spray. Take the intake tube off and have someone crank the car over with the gas pedal floored while you spray the stuff into the throttle body. If it runs this way, you have a problem with fuel delivery. If it still does nothing, you've got a problem in the starter or spark delivery. I had your same problem on two instances, one was when the starter went bad, and one was when the ignition coil (TFI) went bad. So if its not fuel it's a matter of replacing things and seeing if it works.
If it is fuel, check the trunk behind the carpet on the driver side where there is a little block box with a red button on top. This is the inertia fuel cut off switch. Sometimes they spontaneously trip and cut off fuel to the motor. It should be pushed in.
If its not fuel, I'd replace the starter. It sucks to do, but from the factory they are faulty. The new one will have a newly designed solenoid and you'll have to splice a new wire on it, which is provided with the starter. Has the car been cranking over a little longer than usual before it fires up lately? Thats a tell tale sign of a bad starter.
Try these things and see what you come up with. If you're still in a hole then let me know and I'll try to help you out some more. Good luck.
