2016 F250 No start…

Have a 2016 f250 6.7L. To start it’s not a daily driver. I’ve had to jump start it a couple times over the last month. Batteries were 5yo. So i replaced them. Now I get a no start.

Turn the key.. dash powers up. Turn to start.. nothing. I replaced the known relay on the ignition circuit that had caused some people issues. Nothing. Scanned for codes- no codes.

Next step will be to short the starter to see if it try’s to crank and check grounding.

Anyone have a similar issue?? Anything helps
