Yo,
My gas gauge is not working correctly or actually not at all. Im thinking about getting a new cluster, but i was wondering if it is just a short....anyone have any ideas? i need help asap!!!!!
could be the sending unit as well, yo.

whats the "sending unit" i have a 95 sunfire btw
It's the sensor in the gas tank that tells the gauge how much fuel is in there.

I am having the same problem. I too would like to know how to fix this.

yes, it floats in the tank
To determine if the fuel gauge or fuel sending unit is bad,U have to ground the power wire at the fuel tank to achieve this answer.U ground the power wire which feeds the gauge on the dash a signal of how much fuel is in the tank,if the gauge reads EMPTY ur fuel sender is bad,if the gauge reads FULL it's the gauge that is bad.U will need to check a wiring diagram to verify the actuall wire color and or number on the wire to ensure u have the correct one before doing so.So bottom line if the sender is shot,U have to remove the fuel tank to replace it,and to have a shop do it is expensive.Hope this better explains what u can check to see exactly which it is.More than likely its the fuel sender GM sucks on those and tend not to last too long,plus if it is the sender U should go ahead and install a new fuel pump,it will save the time an money later down the road.

Hmm, I think it is the purple wire that feeds the guage for the fuel level signal. Can anyone confirm if this is the wire that needs to be grounded to verify if you have a defective fuel guage or a defective fuel sender?
If it is the fuel guage, is there anything that can be checked/done before actually replacing the cluster?

The only thing that really comes to mind is to ensure the wiring going to the fuel guage is connected properly and that's about it.Sometimes a loose wire that feeds the signal to a gauge may be loose in the harness or have a short from a crimped wire preventing a proper reading.As for the any other possibilties I do not know of any.I have had ALOT of electrical exp and normally as in my prev post its either the gauge is going or typically the sending unit in the fuel tank.Hope this helps you.
