hey tony.. im trying to figure this out for you but what do you mean by this statement? is it turning over but not firing up or is it not turnoing over at all?

from what i hear try 2 things.....

- pull fuel line and crank engine over see if you have fuel comming to the engine past the filter..

- pull at least one spark plug from a trailing and from a leading and crank engine over to see if sparking

hope thatll help u out
