Might be a bad gas gauge
same with temp gauge. If you ground out temp sending unit wire does the gauge move to H. If it does then there is a problem between the two or the voltage regulator for dashi s no good. See if your green wire going into the dash if pin is marked it should be #6 that is power feed to gauges. Then check the fusible link in pic i'm sending.
Sounds like you don't have voltage feeding the gauges. Look for a voltage regulator plugged into the back of the cluster. It cycles on and off like a signal flasher.
