No, you cant damage the unit by overfilling. The probably cause it the sending unit or dash guage itself if your gauge is acting irratic. The only way to tell is to have a tech test the ohms on the guage to verify proper operation as the sending unit will set you back a few hundred bucks and the tank has to be dropped to replace.

04 Buick rendevous. Hit curb and now won't start. Fuel pump kicks on and it's getting spark but will not start. Any ideas?

Is there B+ voltage to the fuel injectors ? Blown fuse's ? Security light lit on the instrument cluster ? If the vehicle will run with you sparying starter fluid in the intake , low or no fuel pressure or injectors not spraying fuel into the engine. Hooking up a fuel pressure test gauge an checking pressure an flow would be the thing to do , not guessing ,because you hear the fuel pump turn on . That does not mean it's making fuel pressure . Your best bet , take it to a qualified repair shop .

I want to find out what gas to use to get the best mileage in a 02 buick rendevous

Use whatever is recommended for the car - it'll be printed next to your gas gauge, on a label inside the gas filler door, or in the owner's manual. The recommended fuel from the manufacturer is the fuel they ran when they calibrated the car's sensors, computer, and fueling system, so you'll do best with their recommended fuel.

2003 Avalanch fuel gage

You have a problem with the stepper motor gauge that Chevy used in the 02-06? Avalanche. All the gauges use the same stepper motor. They just go wonky and do all kinds of weird things. I have replaced two on mine already and two more are now acting up. There is a guy selling the motors and the repair for this problem on E-bay.

Gas gauge

The sending unit in the fuel tank most likelt went bad. It is probably a coincidence that it happened at the same time as the oil change.
