Find the starter..Google if ya gotta the starter is near the bottom on most makes...give it a couple of taps with a hammer.. if it starts you need it to be rebuilt if it doesn't you need a new one....(assuming your battery isnt it)
try park and neutral. if that works, replace the neutral safety switch.
that's what my dad is telling me thank you I will post again for more questions. Thank you.
you might have a bad starter.
