No restart after fuel filter change Diesel

[Murry]

Changed both fuel filters today on my 2012 F350 diesel. Followed directions and reprimed the engine numerous times but still no restart. What am I missing or is there another way to prime engine?

I doubt it is different between the years, but I KEY ON for 30 sec, then KEY OFF FOR 5-10 sec, repeat about 5 times or so and it's good.

Got the Beast restarted. Killed batteries during multiple prime attemps. Put batteries on chargers and primed again, more than 6 times, and she fired up. Running wheel now but did learn to listen for air return into tank. When air stopped, or gurgleing stopped, restarted with a little cranking. By the way the temps have been in the tweenties all week so batteries were low from lack of use.

At least this wasn't as bad as when I changed mine... I forgot to close the water separator valve and lost prime halfway up a hill behind my neighborhood. Killed my batteries and had to be towed home... Finally figured out where the low pressure fuel test port was on the fuel cooler and burped the air. Been running great since.

Where might I find this low pressure test port to better purge the air other than disconnect and reconnect lines on engine mounted filter

I guessing the new 6.7 isn't as finicky about dry firing injectors ?

do that on a 6.0/6.4 and you might be replacing some or all

God I hope not, ran it for two days now and it seems good, good acceleration nice idle so I figure no injector problem.
