340 w/ 727 auto won't turnover

Trying to crank motor over and nothing but a click. Checked battery, starter relay and changed out the starter. Thought about the neutral safety switch but by passed that and same result plus I'm assuming when in park that would not matter. Never had this issue before. Drove the car right before this happened with no issues. Parked in driveway and drove into the garage that same day. About a week later nothing. Any solutions anyone may have would be great. Thanks.
