Just happened to me while towing my 14K 5er and new load of fuel, First had REDUCED POWER warning, then about 30 seconds later loud bang from right side of engine, then no power and pulled off to side of highway. Subsequent attempts to start engine resulted in raw diesel fuel leaking onto road new right front tire. Towed into nearby Ford dealer, immediate next day report of contaminated fuel, water in the fuel and metal shavings - and an immediate report that Ford ESP will NOT cover flushing the fuel system! Then about noon service advised no fuel pressure, I mentioned again the loud bang at shutdown, and they then said High Pressure Fuel Pump (HPFP) failed, and new estimate about $10,000. So, week later I called Ford ESP - there was no claim for repairs from Ford dealer and I had to open a claim and I had to tell Ford dealer to make a claim on the ESP so that an ESP inspector can inspect the damage!!!!! Can a Ford dealer on its own deny any claim under the ESP???? FYI record rainfall in the DFW area, and we continue to break the rain records, my 2011 F350 sets outside all day every day, and I usually refuel in the rain...... water in the fuel, go figure. Oh, and ESP does not pay to tow the truck and an RV hitched to the truck - surprise, another $150 if you're towing and fail on the raod!
