When the problem started, It would turn over the starter but I would not hear the seatbelt noise. Try again and the seatbelt noise could be heard and it would start instantly. Over the next week it got harder and harder to start. I don't even need to turn it over all the way. If I don't hear the seatbelt noise it will not start. If I hear it it starts on the first crank of the starter. Sometimes Moving the tilt steering up and down would help. Now it's gotten worse and almost never starts. When it starts it will run forever until I shut it off with no problems.
