hi ive had my car sitting for a month or so,(havent been driving it,driving my other car).and i jumped and it started up fine no problems.did it a few days after that as well .i didnt start it for the next 2 days which were extremely cold then go to start it and it doesnt start.i went to jump it again and it started but then shuts off very quickly.im wondering if its possibly bad gas?or fuel lines frozen??im not the most mechanically inclined man there is so im guessing here.but im know you experts can help.could it be those symptoms and if so what can i do to treat it??thanx ahead of time fellas

 

Have you never seen "The day after tomorrow"? Fuel lines don't freeze until like 215 or so degrees. So uhh...I'm just about positive it's not that. But it could be a ton of things...alternator, battery, start...but the cutting off problem could be your fuel relay perhaps..or some other things.

 

Sounds to me like a bad alternator, and possibly battery.
