wont start. it turns over but wont start.
Does it have any gas in the tank?
But seriously… give us some more details, please. Are there any other issues or problems?
Check to see if spark is getting to the plugs. If not then check for power getting to the ignition system. If it is a fuel delivery problem then spraying a small amount of starter fluid into the intake should show some signs of life when the engine is cranked over.
