Ok, car has been siting 6 months. We just got it, put in a new battery. It has about 1/4th tank of gas. Cranks over, does not start. I'm thinking it's probably the fuel gone bad since it's been sitting so long, so should I drain fuel and put in a new filter? I'm gonna pop some new plugs in there as well. BTW: do they let you "Borrow" compression/ spark testers at Autozone?
