My gas, volt meter, speedometer and tac work fine but my oil pressure and temp gauge are dead. I have grounded everything and made sure all the connections were good any ideas??

 

oil pressure gaugs has a little IC chip that is bolted to the bell housing of the car. It if that isnt grounded properly then it won't work. Also the stupid connection to the oil pressure sending unit comes off easily check that.



As for fuel gauge, anything goes. Start proping with a multimeter and check everything out.
