My temp light doesn't go on, the bulb is not burned out. could it be the sending unit or is a wiring issue more likely? I am considering an aftermarket gauge instead, any recommendations on that?

ground the wire at the sender to see if the light comes on [ it should ] if not follow the wire back to the engine connector at the back of the right valve cover [ ground it there to check the light ] next is the bulkhead connector [ pin # 18 ] and on to the dash [ you could have a bad voltage limiter ]

Does the light come on when you turn the key on and then go out?

there is a reason they are generally referred to as idiot lights. by the time they come on it is generally too late. you can install a factory temp gauge to replace the light. the stock gauge doesn't tell you engine temps but i guess it tells you what is normal where a aftermarket one will tell you what is going on. also if your truck has a oil light you can replace it with a gauge. i did all the same things to my 81. it came with idiot lights and i replaced them with stock gauges. i might have had to replace sensors also but that is not hard.

no, it never comes on, I testd the bulb by putting in one that was proven to work and it still didn't come on

Do you have a test light? If so, check for power going to the plug. Get under your dash and find the wires going to the light.
