The battery is fully charged. The lights come on and there isn't a clicking noise. I had the ignition switch replaced and it still will not start
Offhand, sounds like something is bad in the system for delivering power to the starter motor. It could be a blown fuse, damage to the wiring, or a bad starter relay/solenoid. If you don't hear any click when you try to start, it's probably not the starter motor itself that's bad.
