I'm assuming that the issue is the car cranks normally, but the engine doesn't run, it just keeps turning over. It's not entirely clear from your description.
It would likely help if you answered @Dogs question above.
So, if you are cranking the car but it doesn't start, try this:
Turn the key off, pull out the key and wait at least 10 seconds.
Put in the key back in and turn on the ignition, but don't turn the key all the way to where it starts cranking.
Wait for 10 seconds.
Turn the key to engage the starter. It should start, as I'm thinking it is your engine immobilizer, as I had a Subie that acted the same way.
Good luck and report back.
