I recently purchased a 1985 Fleetwood Brougham d'elegance from my Girlfriend's father. He hadn't driven it in about a year. (However, all was fine the day he parked it.) After charging the battery I tried to start it with no luck. The motor turned over fine, but it would not fire and run. I siphoned all the gas i could out of the tank, and put 10 gallons of premium in there, along with some fuel stabilizer to take care of the remaining bad gas; changed the fuel filter, and the spark plugs. For all this I was rewarded with the car running for approximately two minutes and then dying out. Now it is back to turning over with now fire. Any advice?
