No problems before I tried to start the car today. When I turned the key, I heard it barely turning over, then it stopped. Tried again, not turning over. I could hear the pump priming behind me. So I popped the hood...and saw some smoke and smelled something burning. The smoke was around the passenger side close to the firewall. It possibly could've blown that way from wind, but that's where I saw it. Could this be my starter? I don't know much of anything at all when it comes to engines. If it possibly is the starter, how difficult is it to swap out? How much would a used starter cost? What else could this be? Thanks in advance.
