If all this is going nuts, First I would check the battery ground. Next check the altinator output. It sounds like therre is a power drain .

The ground wire between your engine and frame is loose or missing. Since the battery and alternator are grounded to the engine and the gauges are grounded to the frame, if you don't have a good electrical connection between the two the gauges will go gaga.

if you just turn the key on and stand outside of the truck shake the truck violently watching the fuel gauge if it goes crazy your truck needs a fuel level sensor due to corrosion
