As @vipergg mentions… you dont give us much to go on here. For all we know it doesn’t start because you aren’t trying to start it, based on your post.
However suppressing my natural wont to be a Wise A$$ we need to know if it is dead battery wise or if it has a strong battery and turns the engine over normally and will not start… Two entirely different scenarios and until we know which…we are as stumped as you are.
