could gas go bad after 2 weeks my 2002 eclipse will crank but will not stay running longer than 2 or 3 minutes
Gas doesn't "go bad" ina short period of time. Something else is keeping your car from running. Any other symptoms?
Replace your fuel filter, sometimes after a car sets the crud that is normally floats around settles in the bottom of the tank and when you turn on the key it is immediately sucked up and plugs the filter, while the filter is off try cycling the key a few times and catch the fuel in a can just too see how much crud and water might be in the tank, if there is a lot of water then add some fuel dryer, if there is a lot of crud I would have the fuel tank cleaned. If all of that is good then check the computer for codes and we can go from there.
