Here is the deal. Back the 6.4 powerstroke sled puller in corner of shop in November. Started working on it. Had batteries in hooked. Converting to single battery. New intake piping and making some changes for up coming season. Hopefully making it to rudys in April. Go to fire it up last night, jump stared with key off to pump oil to top of motor. Go to start the truck and I have a no crank and no start security light flashes and mini max can't communicate to pcm. What would be the fuses to check o any other help?

i found out it was my kill switch. I would check the fuses under the hood. first row second one in from passenger side is the one I had kill switch wired into and put fuse back in and the issue was fixed. going to a air shut off this year so I don't have to worry about anymore electrical.
