The high pressure fuel pump failed, causing the truck to lose power while merging onto the interstate. Our vehicle did not die completely, as I've heard most do. If we had been hauling our rv, it could have been catastophic in that situation. Ford has had these pumps recalled on other vehicles (a van?), but because the repair is costly, I believe that Ford may not want to recall these vehicles. The worst part of it is that anyone that owns an F350 buys it to haul something. In our case, a 13000 pound rv. If we lost power steering and brakes in the mountains of Colorado and Wyoming, it would not be good. Every mechanic we talked to about this seems to feel this is a common problem on the F350 6.4L powerstroke

I recently purchased a 2008 Ford F350 diesel crew cab pickup from hayford Ford in isanti mn. I have driven the vehicle a total of 1500 miles since I purchased it. The vehicle has been in the shop more than 20 days since I purchased it. They now say I will have a bill of $8000 dollars to repair the contaminated diesel fuel system. I understand that there has been a fuel tank delamination issue on these vehicles that causes this problem. That can lead to a stalling of the engine if not detected prior to total failure. Ford will not even honor the warranty I purchased from them. I noticed the increase in engine oil volume prior to any failure which led Ford to diagnose a fuel pump failure prior to engine failure. I understand there have been failures while the vehicles are in motion, which would cause the possibility of serious accidents.

Getting on freeway and trying to reach and maintain posted speed limit. Vehicle started sputtering then check engine light came on. I could not safely maintain my speed so I had to put flasher on and pull off the road. I quickly found out that the vehicle went into to limp home mode so with my flashers on I proceeded to head home which was 40 miles away. I indeed limped my vehicle home as I could not maintain any posted speed limit and created what I thought was an unsafe condition for other drivers as they were trying to pass and get around me. After making it home I found out that there is a known manufacture defect with a publication date of April 27, 2011 tsb 11-4-22 6.4L lacks power-dtc P0088. I pulled my engine codes and I indeed had the P0088 code which is fuel rail pressure too high. I called my local Ford dealership to find out if there was a recall for the known manufacture defect. The gentleman put my VIN# in and told me there was no recall for that known defect from Ford. I've done my research and there are many people out there with this same problem. Ford has admitted to the known manufacture defect by creating the tsb with the publication date of April 27, 2011
