You might have a bad ground. According to my Haynes manual's wiring diagram, both gauges share the same ground and typically that is "located on the left side of the instrument panel", wherever that is. Sorry I can't be more specific about the location. While it may not be true on your vehicle (the wiring diagram states "typical late model" in its description), my wiring diagram says that the ground wire is Brown (BR). You might try locating that wire and track it to its attachment point. You also might try tapping into it and using a continuity tester and ground out the wire to metal (there's plenty of grounding points under there). Make sure the ignition key is off!! There might be a bad ground wire closer to the meters than the attachment point. Hope this is helpful. Allow plenty of time if you're going to investigate this yourself. Do you have other gauges? Do they work? I think that all of the gauges are ganged through the same fuse (but not through the same ground wire). You might consider checking the fuse to ensure that it's OK. Your owners manual that came with the truck will tell you which fuse is it. If there are other things on the same fuse and they work, it's not the fuse. I hope that this is helpful.

find the wire that goes to temp sender and apply earth to it turn ignition on the temp gauge should read hot if it does replace water temp sender if gauge dose not move gauge needs replaging

If you are handy with small hand tools and a Volt/Ohm meter then it would be worth a try to check the problem, older cards the fuel guage is problematic. In the tank in a wire wound resistor connected to the float in the tank, every time you change the fuel lever the wiper rubs the wires and over time it either breaks or gets coated with crud, it requires removing the sensor from the tank and cleaning it. To test however you can follow the wires to the tank and remove the connector, if you have a fuel pump in the tank then you will need to check the wiring diagram for the correct wires and colors. You then measure the resistance across the two wires for the sensor, open circuit means the part will require removel and repair, anything from zero to about 120 means it is probably working, you can also short the wires going back to the gauge and turn on the ignition switch but don't start the car, if it read full then remove the short and it should read empty, the gauge is working. Temp gauge same process just the sensor is under the hood, same process measure resisitance. If you are going to try this yourself I suggest a service manual from your local parts store. If you choose to then take it to a mechanic you already know what to expect. I don't suggest removing a fuel tank alone, it requires jacking up the card and having something to raise and lower the tank. You are working with flamable liquids and you can be seriously injured or killed. Take care folow instructions and you will be fine. Wish it were simpler but this is what a mechanic is going to do as well.

If
all voltages checked ok, then most probably its faulty instrument cluster board
on which gauges are connected. Yes if cluster circuit board looks ok, then also
it can be faulty. Somewhere there is minute short or burn on board then such
problem arises.
Also
check the fuse box. One under hood and other under dash.
Inspect
each and every fuse and see if all are fine or not.
