1999 Saturn Other

My Saturn 1999 SL2 would not start one day after work. When I turned the Key I get a clicking noise. I changed the starter with 3 diffrent rebuild starters from Auto Zone now one did nothing and the other 2 make the same clicking noise and don't turn the motor over. I have taken the current starter back to auto zone they tested it and it check out good. Please help I am running out of ideas.

2 problems I see are: 1-was the starter really bad?
2-Autozone electrical parts are crap in my experience.

Therefore, need to diagnose the problem first, then replace needed parts with quality parts. I know this doesn't help answer the problem, but.
