What is your question?
FOR EXAMPLE: I just filled up the tank-my gauge indicates maybe 1/4 tank-I drive 2 miles-gauge indicates maybe 3/4 tank-next day when I start the car, gauge indicates maybe "empty"-I drive 5 miles, gauge indicates maybe "full"-I drive 30 miles, gauge indicates 1/3 tank-next day, when I start up, gauge indicates maybe 9/10 tank-WHEN "LOW FUEL" WARNING LIGHT APPEARS, THEN I GAS UP! Get the picture?

The problem you are experiencing is very common in 2000-2005 Impalas and many other GM model cars within those years. The gauges had defective stepper motors installed (1 stepper motor for each gauge/needle). Look up GM cluster gauge repair on internet. Your cluster can be repaired with new, upgraded motors for much less than the $400-600 dealers charge to replace your cluster. And if you find someone local that does these repairs, downtime is minimal. Good luck.
A 'scan' test can help pinpoint the problem... it's possible that the fuel sending unit in tank is defective ..OR.. the gauge... that's a scan test performed by a qualified mechanic with a professional scan tool..... not a code reader at some parts store! Got the picture?
That's well and fine 'IF' the tank sender is working properly! TESTING is the ONLY way to know for sure!!!!!!!! WOW!
A simple way to see if your fuel module is malfunctioning is to observe whether or not the low fuel light intermittently lights up when gauge is fluctuating from full to empty. If the gauge gives erratic reading, but never illuminates the low fuel light, then the cluster stepper motor is the culprit. I'm somewhat familiar with these defective Switec stepper motors as I've been repairing GM gauges for 5+ years for individuals and several GM dealerships in my local area. WOW!!
LMAO!!... Ever use a real scanner??..... After you have been doing this for 40+ years.... get back to me!!
Have you ever actually opened up any gauge cluster and actually repaired the circuit board or were you just trained to use a scanner and end up just replacing the cluster like most technicians? You're obviously are a dealership man. Yours is the same reaction as when I walk into a dealership maint. bay and make repairs to components the dealership techs were never trained to do. LMAO!!
