ok my code is P0455 Evaporative Emission system leak Detected (Gross leak) No flow i don't know what that means?
AND another thing I had filled my gas up and next thing you know my gas gauges start goin down it and my gas light would come on but it has gas in there and 30 minutes after I let it sit my gas gause starting showing that its full I really don't know what it means but my gas does runs out pretty quickly could you tell me what I might need to get done
That code is for the evap/emissions system. In some causes it could start causing the car to malfunction. Common thing to check would be the gas cap, without further inspection, it would be hard to say. As for the gas light and float, I think that the sensor has gone bad. Replacement of the assembly should fix it. Shouldn't be too expensive. As for using a lot of gas. No idea. Get a proper inspection done on the car. It should tell you what you will need to do next.
For P0455 see below:

Gas caps on these can cause small leaks, not gross ones. Sounds to me like you are leaking fuel somewhere. Possibly from one of the evap lines on the tank or up front behind the motor. Really need to have a mechanic get it on the lift and diagnose the problem. I wouldn’t continue to drive it right now, very good possibility of a car fire.
