No Fire

For the GT, if the only thing wrong is a bad cam sensor, the motor will still start.

A bad, disconnected, or incorrectly installed crank sensor (CKP) could cause a no start with no spark. There are also other possible causes for a crank with no start.

If this were my car, as has been suggested, re-check the work. Check all fuses and GROUNDS.

Then I would check for +12 volts with the key on to the red ignition wire. IMO the easiest place to check is at the ignition interference capacitors. If no voltage is present, STOP and find out why as it will never start.
