No start post fuel filter change
Went and changed my fuel filters today... Primed the truck 6 times. Started it. Ran great, then got a low fuel pressure and reduced power notification. Turned it off. tried priming it 10 more times, no start, tried 15 more times. No start. Took off the outlet on the secondary filter, solid flow. Took off the return on the L/H fuel rail, pinched the line and put a hose on the rail... Once again solid flow.
I can hear air somewhere under the hood but I don't know where... Driving the 7.3 to work tomorrow but this is driving me up the wall. Ideas? Suggestions?

it is possible that the change happened as the hpfp was on its way out. Doubtful. You still have air.
Charge your batteries and purge somemore.

Heck, if it's that bad try putting the old filters back in. Or, drain the new filters out and start over.
I'm considering installing each filter individually in the future. Do the bottom one, prime and run, then the top. I've had a hard time lately getting the purge to settle in.
