I got a brand new battery 12.6V, and it cranked fine but would not start. I charged the new battery up to 12.9 volts and it fired right up. The strange thing is I have 2 , 2013 grand caravans. the old battery works in one van but not the other. Another weird thing is that when I jump started it and it started, It would only rev to exactly 3000 rpm. but after i let it run half an hour and charge the new battery up to 12.9v I could rev it up way over 3000 rpm.
I dont think my multi meter will test how many amps the starter is drawing.
You've gone online, asked the questions, and got good answers. Now take the vehicle to a local chain that will test the starter for free( I see autozone is 15 mins from you) and go from there... Let us know what they tell you..
if it all tests good you have a deeper rooted issue like a ground problem or component that is requiring extra V/I to function
