temp guage not functioning
Stock 1990 5.0 LX
I just noticed my temperature guage has stopped functioning. The guage pointer does not move. All other guages function normally. My Ford shop manual is very poorly written on this topic. I have no electronic testing devices. After checking wiring & connections, is replacing the sender the first thing to try? Thanks in advance.

RE: temp guage not functioning
I'm not one to normally suggest just replacing parts, but the 2 coolant temp sensors aren't that expensive at an auto parts store. I got both for $30.
Try this first though... Make sure the sensors are still connected and the wires are in good shape. One CTS is located on the black heater hose tube that goes into the lower intake <runs parallel to the fuel rail on the pass. side>. The other is on the driver's side at the front of the lower intake by the #5 injector.

Thanks gspfunk. It says you're from Dallas. Me too. You are right. A person can't run around recommending to just start replacing parts. I did finally locate a post for this problem where the suggestion was made to remove the wires from the sensor, ground them, and if the gauge reads full hot, the sensor is definitely bad. Would you care to comment regarding this method of troubleshooting? Perhaps elaborate in a bit more detail how to do this? Thanks again in advance.

The dealership where I normally get parts wants less than $20 for the one I think I need, but it is out of stock, so i will wait until they get one in.
Sounds like we're practically neighbors. I will post later as to whether or not this fixes my problem. Thanks again.
