Car won’t crank just turns over and clicks, has new starter, alternator, & fuses

What is your question?

Won’t start when u turn the key it just makes a click sound but won’t crank but the radio, lights, air conditioner, etc do come on. The starter and alternator and fuses were replaced and it cranked for a couple days then went back the same not cranking issue. It’s not the battery since everything in the car works, and it doesn’t even try to crank it just clicks. No leaking out of the ordinary and no other issues.

What makes this problem better or worse?

Nothing
