I am having starting issues with my truck. I took it to a parts shop with a scanner and the guy hooked it up and ran some tests and he said everything was where it was supposed to be as far as battery health, starting, and charging, except his machine was reading 640 +/- cca instead of 550 as the battery is rated, so he suggested that maybe it is the battery. So I replaced the battery and it still does the same thing. It cranks very slow, so slow it takes multiple attempts to get it to fire. Every once in a great while once warm it will turn over at a normal level and start, but that has been rare. Doesn't that sound like a dying starter? I'm hoping I can return the battery, which was about as much as a starter. I checked all the cables and connections, and everything is how it should be.

Yes it sounds like the starter is faulty. Take it to an auto parts store like AutoZone where they can test the battery, alternator and starter for free.
It could be a starter. If you try and start the car a couple times does the battery end up dying to the point where you get nothing but a click when you try and crack it. If so then you most likely have a bad alternator. Now if your just cranking away at the car and it wont start but the batter is still providing enough juice to keep trying to start it, but its cranking really slowly then yes its very possible the starter is shot.
