I have a question regarding an 05 chevy aveo.?

[Krista]

my car has been sitting in the drive way for about 3 months hasnt been driven anywhere and now it wont start up anymore, I've charged the battery and everything, the car is turning over, it just wont ignite for some reason, ive checked the fuel line, ive cleaned the fuel injectors, ive cleaned the electrical units, ive checked the fuel fuses, the car is getting sparks, the spark plugs are still in good condition, and i have gotten the car to startup twice and now its a complete dud again, i have no idea what to do now about it, i wanna try to save on autoshop costs, any ideas would be of help, thanks!
and the car is only at 40,000 miles

its probably bad gas from sitting gas separates when it sits, try getting a can of seafoam you can get it at an auto store like autozone or a retail store in the auto department, the gas could be settled and not burning right when going through the engine. its about 5 dollars, so give it a try.
