i've been parking my car for about 3 week, due to the totally broken flex area. last time it was moved was for the snow emergency (1 1/2 weeks ago) well now i got warpspeeds whole setup. i wanna take it to a shop but now it wont start. last week my dad was about to take it, it started but then quit. currently i just barely got the thing started...ran 20 sec then quit. i threw some hot water over the fuel filter...was the only way to actually get it running
would it be:
bad gas (from 3+ weeks ago)
too cold (minnesota)
o2 sensor (did run before it got really cold)

so far it seems to be a cold thing (17 degrees celsius too cold?)but any help would be cool

Just a guess, maybe the fuel filter dried out from leaving the car for 3 weeks parked. the crud that was in the filter dried up and clogged the passages.
