fuel and temp gauges died how do i fix

Both my fuel and temp gauge went out during a smog check, car was idling like crap and kept cutn out when they were done, it failed, took it home fixed the idle it passed when I took it back, I think they were messin w my truck so it would fail, they probly thought I ddnt know anything aholes. Any how I chose the path of peace instead of pissed and let it slide but my gauages are done sometimes they move a lit. tle but somethings wrong. Idk if its the gauges themselves that burnt out or the actual temp sensor and fuel level or sending unit. Has anyone had this problem n got any ideas or answers thanks for any help
