So what's the update JAKE. Were you able to find out why the motor wasn't spinning up.
Do what Dart says and pop the motor plate off to make sure that the motor height is not jamming the gears. Also, while you got it dropped and the wires still hooked up, see if the motor spins up, before you pop it back into the handle. If not, check the fuse if it has one.
You might also want to check the trigger switch in the gearbox as well if the fuse checks out and the connectors on the motor check out.
