My “01” Sable with 3.0L OHC engine at time will not start. When this happens I have fond out that if I remove the gas cap it will start right up. So far I have replaced the gas cap twice (2 different brand names). The battery is strong it turns the engine over with ease. I took it to the local Ford dealer and left it ther for a few days of course it always statred for them, they suggested it might be a week fuel pump. This would be avery expensive guess. Any Help!  
  
  
  
 Thanks,

They shouldn’t have to “guess” about a weak fuel pump. They can test the fuel pressure. I’d find an independent mechanic and get away from the dealer.

Try this: Turn the key to “on” and wait five seconds before turning the key to “start.” See if that makes a difference.
