I did a fuel filter change a couple days back and it went perfect with no issues I purged the lines 6 times like I should and when I go to crank her over she won’t turn over. My friend then came over and helped me, after hours of purging the lines we got the truck to start, I then took the truck on a 10 mile ride and it threw a low oil pressure light and put my truck in limp mode I did not get a CEL and after 10 minutes in limp mode and being reduced to 30 miles the truck shut off on me and I had to get towed home. After that I’ve tried purging all the lines for days with no results. Yesterday I removed the fuel filter return line and started priming the truck, it would let out a bunch of bubbles and air along with diesel, after priming like that 6 times for 30 seconds until the fuel rail pump turns off each time. It would get better the more I would purge the system but every time I try to crank her over no luck. The truck is giving codes P2291 and P008A. I’ve made sure the fuel filter is as tight as can be and is not sucking up air anywhere the o ring is lubed and put perfectly where it belongs.I used motocraft filters. Any help would be greatly appreciated thank you!!!

Can’t get my 6.7 to start after fuel filter change.
Your batteries are low from cranking, and you're getting air still from somewhere, odds are the frame fuel filter still. Even if YOU think it's fine, it probably isn't. Oring could be compromised, still have air in the system etc. You also posted in the 17-19 section.
Thanks ill move it over to the other section I hadn’t realized. I’ll recheck the air filter although I do believe it is fine and hook up a battery charger even though my batteries are a couple months old
