It sounds like it may be a few things.
1 - Starter solenoid
2 - starter itself
3- neutral safety switch preventing unit from cranking.
CAn you hear solenoid click when trying to start engine. If so then it is the starter if no click then solenoid.
Make sure gear shift is in park because if not it will not start either. The newer vehicles require your foot also to be on the brake or nothing.
Hope this helps.
