Help ran out of gas and filled up and now won't even crank? The battery is fine and I can hear fuel and everything running just the engine won't crank to start. It did a few times and now it stopped cranking. The worst thing about it I'm on vacation 5 hours from home with my wife and kids and its Sat night and no dealer open on Sunday? Any idea what if could be? I was told it may be a sensor that shuts the car down when to much air is in the system! Any help asap would be greatly appreciated.
