My gas gauge worked when I test drove car. When I picked it up, it was not working. I replaced the sending unit and it still does not work. Anyone have any ideas where I should look now?

 

See if the gague is broken.. Get a volt meter on the wires

 

I don't think gauge is broken. When I start the car, the needle moves a little, up to the "2" and that's it.

 

The only way to test is to check the voltage of all electrical components... since you replaced the sending unit the next logical step would be the gague. Check a chiltons wire diagram and see what else is in the circut.
