I have a 1998 Mustang GT. I have let it sit for approximately 5 months without starting it and it will not start now. It turns continously but it will not start. I sprayed a couple sprays of starting fluid and it started and ran for 2 seconds then backfired really loud and shut off. Could anyone give me any advice on how to start it? I am an idiot for letting it sit for so long with out starting it. Any adivice would be appreciated!
