safety Lanyard attached? have to ask?
neutral lockout working correctly? move throttle forward back try to start...check wire connections on lockout switch.
Jump safety lanyard as a possible solution.
You can also jump the neutral safety safety lockout on tranny or you can check continuity - switch should show closed circuit in neutral....iirc.
