Check your fuses, if ok..You need to replace the sending unit for this gauge.

If you live in the northern part of the U.S. use 5w30, in the south use 10w30.
195 degrees F
What are you talking about? My temperature gauge works fine. Though, if it wasn't I would check the temperature sending unit.
Most likely a bad sensor/relay
inertia
The sending unit is probably bad, not unusual.
It's a GM
When the check gauge light comes on in the 1995 Chevy Cheyenne, it means there is a problem with the transmission. If the truck won't shift in to overdrive, there is most likely a problem with the VSS system. The transmission needs to be removed so the VSS can be accessed.
are you sure you reconnected the wire to the gauge when you did the fuel pump? also the gauge requires a good ground to the tank. its possible you don't have a good connection. just some thoughts.
where is heatercore in a 1995 Chevy cavilier
