Why wont my engine turnover at all?

How do I change the starter, as well as locate it?

So my car was not running due to a stereo wire grounding. I fixed it and then It worked for a day. My ignition fuse blew so I replaced it with a new one hoping that would fix it, but this far it still is not running. When I turn the key on and push the clutching my cooling fan turns on external lighting is good and does not dim. But my instrument panel oil and engine check light are exceptionally dim. Fuses are good in cabin and under the hood grounding wires in engine compartment are good and my battery is good. Any ideas what could be causing it not to start.

Also, I forgot to add that the relays click on when I turn it to start.
