i have a 1992 rs camaro with a 350. it has TBI with flowtech headers and 2 1/4 inch exhaust (side pipes with glass packs). no serious mods done to it yet...air pump is gone that sort of thing but my gas, oil pressure, and temp gauges dont work now...not sure why, they worked when the 305 was in the car (except for the fuel gauge). i think my fuel sending unit is bad but i havent had the chance to make sure...any other clues?

 

Id start checking sensors. Thats whats wrong with both of my temp gauges. The sensor is bad..

 

thanks ill check it out

 

Make sure they are hooked up. I drove around for like 6 months thinking that my temp gague was blown. Then I changed my spark plugs and while I was in the area I realized that somehow I had disconnected the wire to the temp sensor. Plugged it back in and the gague works fine again.
