Stock water temp gauge problem?

Had a needle sticking on the temp gauge so I took apart the bezel and freed the needle. Turned the ignition to key on but did not start the car and you could see the needle move a bit and settle into the bottom 100 degree part of the gauge so I knew it was getting power. As soon as the car is started the needle instantly pegs. I have a new sensor but haven't tried it yet. That will be my next step but was just wondering what everyone thinks could be causing this? Thanks!

Sounds like the wire is disconnected and laying against something metal. (shorted to ground)

Sending unit (not really a "sen-sore" [/mr.spock]) might be fine... try hooking the wire up right.

I guess I assumed something that simple would have been checked but, you never know.
