This can be a number of things. First, a loose or corroded ground connection or the connection at the sending unit. Could be a bad connection at the dash. Could be a bad sending unit in the gas tank. Or, a bad gas gage. Or even the wiring in between. You will need someone who is competent at electrical troubleshooting to find the problem. Don't let someone tell you something is bad without even looking at it first or you might buy parts you didn't need.

SOURCE: My 1999 Oldsmobile Alero Gas gauge and fuel system

well # 1 the full gauge when empty is a sign that your fuel pump is bad and that needs to be replaced the part about spitting the gas back out is probrobly a clog between the fuel door and the tank itself or their might be a vapor lock door that might be stuck shut so fuel cant get in im not 100%sure about that but im 100%sure that the fuel guage is the fuel pump being dead.

use a scanner to check the abs system . most of the time the abs brakes and traction control system work together. your cruise control . unit has a servo motor .in front right fender well. check the fuse and relay also the cruise control brake release switch. and the brake light switch.if all is good you have a cruise control module problems. dealer ship job.

SOURCE: 99 chevy silverado fuel gage malfunctions

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 replaced the fuel pump in my 1999 Oldsmobile alero in may of 2012 when I start my car I get a big smell of gas just like I did when it went out before could it be going bad already

I'd use a gage and check proper fuel pressure. Also, check for external gas leak, at the fuel pump--fuel lines--fuel injector/s--fuel pressure regulator, and check evap system.

Gas gauge bounces from empty to full

The needle for the gas gauge fluctuates, it will say empty and the light is on then it will go up and say half full or full and then back down!!!

You need to check your GAS FLOAT terminal, corrosion and oxidation sometimes send an ERROR to ur gauge( DON"T WORRY no spark will happen 'cause thats only a GROUND activated wire) ! After cleaning it and nothing happens you need to bring ur car to the nearest garage mechanic to check on the GAS FLOAT itself!
Taaah!

There is a humming sound coming from the front end of my 1999 oldmobile alero. Only happens when the car is moving. I dont hear itat idle or even when pushing the gas at idle. could it be my transmission...

Hello! If the humming noise is speed related(gets louder as vehicle speed increases)check front wheel bearings. If the noise goes away when turning one way or the other then it will most likely be in the front wheel bearing. If you turn the wheel(while moving)to the right and the noise goes away it is on the right side. If you turn the wheel to the left and the noise goes away its on the left side. Hope this information helps!

My check engine light came on on the right side, and then my fuel gage went bonkers. I was in park and the fuel gage went to empty. I turned off and then it took awhile to come back up to full. I filled up...

I hope you did not top it off because filing it up like that will wreck havoc on the evap system. The engine light should go away as the gas in your tank is used up, or it may take some time, but hopefully it goes away. Just next time you fill up don't top off when it clicks off thats it. Also make sure the gas cap is tight. A loose gas cap can make the check engine light come on. I am an emmission repair specialist, and deals with these crazy things sometimes lol.
