Hi, Trevor.

It's possible that you don't have sufficient battery voltage to start the car or that you've blown a fuse that provides power to the engine control module or something else critical.  I cannot think of anything inside the alternator itself that would prevent a cranking engine from starting.

I'd recommend first checking the fuses, especially the main fuse.  

If all the fuses are okay, check to see whether the check engine lamp illuminates when the ignition key is turned to the on position.  If the lamp doesn't illuminate, you should suspect a problem with the PCM powering up properly.

Otherwise, resort to the typical checks.  Do you have spark?  Fuel pressure?  Did the engine jump time?  Figure out what sort of issue you have so you can develop a strategy to investigate the cause.
