You have what appears to be a systematic failure of your wiring system supporting those gauges. There is either a BIG short or source of spiking voltage from either a Dying alternator or something else that spread the electric storm under your dash affecting everything until they burn out. Or burn if you have a hot enough short to ignite something.
That truck is not to be driven at all until a shop has had a chance to trace each one of those gauges and it's associated wiring, sensors and so on all the way back.6wheeler Thanks this. -

Sweeping gauges mean it is not recieving data.
