HEART BREAK
I picked up my truck today from the dealer. It has been in the shop for 11 days. 7 days waiting on parts from ford. Ford replaced the complete high pressure fuel system under warranty. I am thankful. I drove it home 200 miles all is fine. the second time I crank the truck and lave the driveway, I get the low fuel pressure warning and reduced power. It seems that I can not get a break.
I am sure the low pressure pump has gone bad again. This will be the second time.
It looks like another rental car for me.

Hi, sorry about your troubles. If you have low lift pressure, the low pressure fuel switch should keep the engine from running protecting the high pressure pump.
It is possible the first time around this bad switch did not do its job when you had low lift pressure and subsequently the the high pressure system tore itself up. If the problem was not properly diagnosed and the defective ( if it was/is ) switch was left in place.........
Need to have that switch properly checked and then investigating down stream from pick up to lines to filter to see if you have something additional going on causing the pump to go bad like a hole or split in the line allowing the lift pump to gulp air.
Best of luck, keep us posted.

Sorry 69CJ, I was so mad when I wrote the post I forgot. I am driving a 2014 F250 with the 6.7. The truck is 14 months old with 68k miles on it. The original lift pump was replaced at 36K miles. Of course, that was after three trips to the dealer and two rental cars. When it finally came in on a roll back they replaced the lift pump. @ 67K the truck just started shutting off while driving down the road. No check engine light or warning. Just no power steering or breaks. The truck would not restart until it came to a stop and was put in park.
This happen two or three times before Ford would let the deal look at the high pressure system. They found metal and replaced the whole thing under warranty. It's just a pain trying to find the time to rent cars, go to the dealer, wait for Ford to approve, wait for the parts only to find out that when you get it back it's not fixed.
I know I am venting. Sorry for that, but it has been a rough couple of days. The boys and I have a sporting clays tournament next weekend and it looks like we will be without a ride.

Here is an update. I got my truck back again last night. The good news is it's still runs this morning. Only time will tell if they fixed the issue. I still worry that the low pressure system is not correct. This is the third low pressure pump. The last on they replaced lasted 2-1/2 months. Ford did replace it under warranty again.

So sorry to read of your problems with your truck...
Your repeated issues makes a guy wonder if there is somethng screwed up with the pickup assembly in the tank.
If it is allowed to suck air, that will make the pumps work extra hard and they will overheat..

Lift pump failures
At three lift pumps and one HPFP something is going on. I think they pulled the fuel tank and cleaned it when they replace High pressure pump.
I hate repeat problems, replacing the same parts is not likely to fix the whole issues. Crystal can help and I am sure she will be around soon.

The fuel delivery pressure switch will turn on the low fuel pressure warning in the message center initiate an ENGINE DERATE CONDITION when pressure falls below specification for more than 60 seconds. It will not shut the engine off or prevent it from running.

Thanks for chiming in on this.

Hey guys, thanks for all the input. I got my truck back Wednesday night. It has run fine for the past few days. I am not sure they have solved the issue yet, only time will tell. I am still concerned that the truck does not preform as designed with the low fuel pressure. Some time the check engine light does not even come on. Currently, nobody from FORD customer service will even call me back. I was assigned a case and a region customer service manager. I have left her multiple messages and still no reply. I am also worried about piston and cylinder damage on the engine. Nobody has even looked under the heads. FORD has not even offered to reimburse me for the 2K in rental car fees. Love the truck, not so fond of FORD customer service. Crystal can only do so much. They she'd put her in charge.

HI FORD DOC, I have seen two that did.
Low lift no start thru the low pressure switch. Lots of sources for that info as well.
SO CORRECT.
Would not have used all bold letters but you had buddy.
Also, I can speak from 31 yrs. of diesel and hydraulics. I commonly see "TECHS" from dealers and shops that are not exactly well trained in hydraulics.
The three biggies for techs who keep putting in pumps, fuel or oil hydraulic systems they are not decontaminating, second is not diagnosing a "CHARGE" OR "FUEL LIFT" issue or and third is not diagnosing the system and checking for aeration, which causes the cavitation that kills the new pump.
