Coolant Temp Guage

I hate this thing. The car is a 1993 Chevrolet Lumina Euro sedan. V6 3.1 My temp gauge fluctuates from normal temp to hot all the time or it just says its hot all the time even when i just turn on the car. I changed the temp sensor in the engine twice. Then i looked at the pigtail. The wires were burned so i got a new pigtail and soldered it in. It read the right temp for a couple minuates then it shot to overheating again. I'm completely lost at this point. What else could be doing this? Also my primary fan won't turn on but my a/c fan does. I tested the primary fan motor and it works. But it won't turn on when it needs to.

the new pigtail is in right now is burned also? Did you check your coolant level? Hows the radiator cap? I am just trying to see if you covered your basic and easy stuff 1st. Hows the temp itself? T-state opening and closing?

You might be asking about a 2000 Z3 or a 1993 chevy lumina, but I am not sure.

I'm asking about a 1993 chevy lumina when i typed in all my info on the page when i hit enter it used the info from one of my other cars. Yes i check all the basics.
