1995 Buick Regal Starter

1995 Buick Regal 6 cyl Front Wheel Drive Automatic

My daughter's car started stalling on her and then finally stalled and would not start back up. When we try to start the car, all you hear is a click.
Installed a new alternator and starter, but starter still clicks when trying to start. I've checked all the fuses. Is there a starter module and where is it located? Or what else should I be looking at?
Quick replies are appreciated!
