Ford 6.7 Powerstroke

Just to give an update - same Low Fuel Pressure, and Reduced Engine Power happened to me on July 5th.  Had it towed to Riverside Ford in Sumner - where the truck still sits.  They cannot figure out the problem, ruled out any poor maintenance, bad fuel, water in the fuel line, etc.  Riverside contact the regional Ford Rep and escalated the issue - I also contact Ford Corporate - I was told they'll be in contact within 24hrs, starting yesterday.

Riverside noted, that because it has had two fuel pumps replaced to try to fixx the issue, and nothing is noted to be due to poor maintenance, debris in tank or anything else could've caused it - they need help to figure this out, so a Ford Deisel mechanic (from corporate?) is also in contact with them to work the problem - they just don't know what is causing the low fuel pressure - which then causes the truck to reduce power, and die.....

It's likely just Ford Hotline Assistance online. They'll send a field service engineer out in really weird cases but that's not too common. He's probably been here maybe 6 times in the 3.5 years I've been at this Ford dealer.   Any idea what fault codes it had stored last time?  It should be documented on the paperwork you got when you picked it up. Wouldn't shock me if they found an issue with a wiring harness or a pin connector or something along those lines. That seems to be the way a lot of these things go sometimes. The challenge will be for them to reproduce the problem. If they can reproduce it, they should be able to diagnose it. If not, it could be a crap shoot. At this point it's clearly not an issue with the fuel pump itself.

We actually had a truck having the same issue here. The fuel filter on the frame rail was not tight enough and it would suck air. Snugged it down good with a strap wrench and problem solved.

Yeah - thats the tough part - is they cannot recreate the issue.  I don't have the paperwork with me right now from my last break down to know the code - the code however is one that described Low Fuel Pressure, signifying fuel pump problems.  All that has been ruled out.  The 2015 year is when Ford changed the fuel sensor, combining two separate sensors into one sensor that measure fuel pressure...and...something else, I can't recall off the top of my head.  Riverside has been good to me for some time now - even prior to this issue.  They don't see this often at all, which is why Ford Rep is involved.  Not sure what'll happen - I hope they just get it to work right, as I said earlier...its a one off - with how many trucks come out of their assembly line, and this one is the chosen one to keep you scratching your head - it is a big inconvenience, but in the long run - non-issue, as Ford will resolve it one way or another.
