sending unit or float in gas tank, check if any broken wires or well plugged in and then check the float for the gas.

A bad electric connector is possible. A bad tank sending unit can cause the same symptom. Usually the sending unit is a reostat mounted inside the tank.. it changes resistance depending on the float position, the resistance change causes a different voltage to the gauge or signal processor. The reostat may be a resistive plastic strip, as the float moves a contact pointer wipes the length of strip thus the change in resistance and voltage. Clear as mud?

I just had my 99 sunfire diagnosed at a pontiac dealer for this same problem and they told me I had to replace the fuel pressure sensor...

did you replaced just the float , because if the resistor that messures the level is not good you didn't do any thing you have to change the level sensor next to the pump..,Im sure that;s all the problem, you should also check the wiring next to the pumpand any connector down there
