Lack of fuel no spark many reasons give more detail. It turns thats all you say. Did you see if the spark plugs are firing? Did you put fuel in it? Not to be sarcastic but you ask my engine turns but won,t start.
We need more information. What year? Are you getting spark? How about fuel? Those are the 2 main ingredients for starting. Not to exclude compression. If you pull the plugs and they look wet you should be getting fuel. When was the last time it ran? Need to start with the basics so these guys can help diagnose your problem..........
