Dead Temp Gauge?


Jun 11, 2001
I have two wires under the hood close to one another, one is to energize the fuel pump and the other, I believe, has something to do with the temp gauge. One day the wire for the temp gauge was grounded out and the temp gauge was pegged. The other day, I was playing with my fuel pressure and put 12V to the temp gauge wire and it no longer works. Did I kill it? I haven't looked at the wiring yet, I am heading out there now. But I am thinking I may have fried the gauge. Can anyone shed some light on this situation for me?
