When I put my key and try to turn it over it starts sometimes and other times it does not. what can cause that to happen? Do I need to get a new ignition switch? Or could it be something else?

Good morning,

I attached a wiring diagram of the starting system for you to view.

We need to do some basic checks to see if the ignition switch or the starter is the issue.
