why does the fuel gage on 2005 mustang don't work?
The float in the fuel tank may need to be replaced.
The 2005 Ford Mustang runs on regular unleaded.
You will need a fuel pressure gauge. Connect the gauge to the fuel rail and start the engine. The gauge will tell you how much pressure they pump is putting out.
Most fuel gauge problems are the result of a faulty fuel gauge sending unit located in the fuel tank.
Fuel sender inside the gas tank may be block
The fuel pump is located in the fuel tank
In the fuel tank mounted on the fuel pump
I was looking at the 1997 Ford Mustang Owner Guide and it doesn't show a low fuel light in the gauge cluster
id say either a bad ground to chassis on the fuel sending unit (off the top of the tank.) or a bad gauge

might be a bad fuel sender unit or BCM
A bad fuel sending unit, a fault in the circuitry for the fuel sending unit, or possibly a faulty gauge.
