Coolant temp not working...

I'll assume that you have made sure the sensor wire is connected and the coolant system is actually full... So, this is what I'd do (try at your own risk):

 

1) Disconnect the sensor wire at the sensor and let it hang loose, then turn on the ignition and see if the guage shows any movement.

2) Now short it to ground, then turn the ignition on and see what the guage does.

 

Hopefully one of the above will be zero, and the other full hot. If this is the case, replace the sensor, hook up the wire, and be on your way :D .
