My fuel gauge isn't working and temp gauge isn't either. I couldn't find a dedicated fuse for gauges and all fuses look good. Any suggestions? Thanks.

 

Check the position of your ignition key and make certain it has returned to the appropriate position. With the engine running, just slightly wiggle the key and look for the gauges to suddenly come to life. This is not uncommon as the mechanical ignition switch [where the key goes] can stick.

Three gauges are controlled by the ICVR and if it does not get power [during starting cycle the power is disrupted], the gauges fail to work. The 3 gauges are the temperature, oil pressure and fuel gauge. The ammeter is on a different circuit.

David is correct. To add to that, this page has info on troubleshooting the gauges: Fuel Tank Selector & Gauges - Gary's Garagemahal
