Hello,




This is my first post to these forums and would like to thank you in advance for any advice you may provide.


I have a 2011 F250 6.2 XLT Reg Cab FX4


Here's my story:


Got in truck and started per usual. Begin to leave driveway and the truck stopped running. I was luckily able to roll back to driveway in neutral. Truck cranks over but does not start.


I removed hose to intake filter and sprayed some ether(starting fluid) to eliminate any ignition issues as a possible problem. Truck fired right up but died due to lack of fuel.


I was unable to hear the fuel pump turn on while under the truck.


I checked the fuse and swapped the relay under the hood with a known good relay from the wipers.


I borrowed a buddies Snap On Solas scanner and it showed the following code while running a function test - P0627 - Fuel Pump 'A' Control Circuit/Open


I have yet been able to drop the tank to check for power at the pump.


Is there anything else you would recommend I try before dropping the tank?


Is fuel pump failure common on these newer 6.2s?? I searched without finding anything related to this issue.


I also saw that some older models had a relay under the spare tire. Do these models have that as well??


Sorry for so many questions. Any help is greatly appreciated.

 

On the passenger side in the truck there is a fuel shut off. Maybe it kicked off check that also.

 

I thought I read they did away with the inertia switch? Would it be in or near fuse panel below the glove box?

 

In that area. I think behind the side kick panel. There is a pic of a fuel pump I thought.

 

I just got back home to the truck and there IS a small panel with a fuel shutoff sign on it but when the panel is removed there is nothing behind it. I looked in the owners manual and it says to tune key on and off a few times to disable the fuel shutoff feature in the event of a collision. I have obviously tried to start the truck a few times with no luck. Looks like I wil be dropping the tank to check for power at the pump

 

Did you every find the culprit? Or did you just give up? I am have the same issue with my 2011 6.2l. It is intermittent, but aggravating as heck!
Does anyone have any suggestions?

Thanks, Tim

 

I have the same issue, along with a stumble (thread is a few down on the 6.2 page). I just replaced the fuel pump today so we'll see if it fixes it like it did for the other guy, I'll report back in a day or two and see. So far on the 40 mile test drive it's doing good, but it's still going through the learning process.

 

my 2011 i put in 2 fuel pumps not the problem took to dealer the replaced pigtail to fuel pump and has started ever since , they said wires are loose in plastic plug was the problem
