This may be a fuel sending unit problem.To get to it the gas tank will have to be removed. It should actually be a fuel pump module.Before going that route I would check the ground wire and the sending unit connetor to make sure it is not just a bad connection.Fuel Pump modules are generally quite costly.

there is a float in your gas tank kinda like the float in your toilet. Sometimes they stick and if the bell goes off then back.. it prob. from the gas splashing in the tank. I wouldnt' be concerned too much.

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.

Fuel gage


They get gumed up(more so if they have sat for awhile) other than pulling them out of the tank. the easyest thing to do is add some antiguming fuel additive to your gas. it takes some time. It will losen them up.
