slow starts

So i had a bad injector, a result from a bad ficm, which was the result of low voltage (bad alternator) and I got the injector replaced, batteries a couple months ago, and a DC power alternatoer. I have good voltages on the ficm power (main/logic on scangauge) but the sucker still starts slow in really all conditions. I'm going to have the batteries tested Saturday and start there, but I didn't know if you could provide any knowledge or insight on why I'm starting slow? I thought maybe more injectors bad. I haven't run the truck since Monday and I went ti fire her up today and I had to hold the crank pretty long as it cycled and got into its rpm pattern to start. Idk what else to think other than batteries run down a little. But I'm getting 14.6 volts after the delay.

Check to see what cranking RPM's are. It could be the starter getting tired.
