1993 Plymouth Voyager Car Won't Start

1993 Plymouth Voyager 4 cyl Two Wheel Drive Automatic

I tried starting my car after work and it was a bit sluggish in starting(first time ever). I drove home, next morning I tried to start it and nothing. I had the battery checked and it is fine. I rapped on the starter with a small hammer and I did get a click. But still won't start. Any suggestions? Is it the starter or starter solenoid that is attached to the starter? Or is there something else I should try or look for?
If you may think it is the starter, could you tell me the procedure for replacing it?

Thanks
