You may need to reset the ECM (ELectronic Control Module). Try disconnecting the battery completely from the car for a minimum of 30 seconds, then reconnect and try it again.

Thanks for the response. I was checking fuses under the hood and all it actually turned out to be was the 10 amp fuse for the PCM. How crazy is that?
