I can't open the gas door on my chevy aveo.

Is the check engine light on?

You may have a bad sensor or a problem. that needs attention.

As you can see, there is a lock and unlock relay, both.

Pull it out and shake it. See if it rattles around. Worse comes to worse, put a new one in. They don't cost that much.

Sounds as if you may have blown fuses or stuck relay.

easily push it out? Probably not. If you pry against the door, you risk damaging the metal on that. Take it to a body shop and pay them to move it out enough so you can use your door. That won't cost much

Refill it with fuel and it will crank.

Sounds like the fuel door is frozen...:) Inside your trunk or rear hatch...there should be an emergency release cable directly to the fuel door...look inside the trunk paneling...it should be visible for ease of access...hope this helps...also the owners manual should have a diagrahm of the location...

I uually shift into 2nd at around 10 mph 3rd at 25 4th at 33ish and 5th at 40. I get 30 mpg on a 2006 Aveo which only has a 27 mpg rating for my car. The high way is a totally different story. I dont look for gas mileage for quickness. But If you want the recomened shift points look in your manual. I learned the early shifting tric from my 01 focus. It had a shifting light. I got 33 intown mpg with that one

WHEN I WENT TO BAY MY AVEO THEY SEY THE MILLAGE WAS 22 TO 25 MILLAS POR GALON IN THE CITY..............................NEVER. I ONLY GIVE ME 18 TO19 POR GALLON MYU AVEO IS 2009
