2009 Ford F-250 Super Duty Lariat 4dr SuperCab SB (5.4L 8cyl 6M)
Model selection feature on this site is messed up.
My 2009 6.4L has 86,000 miles on it. On recent trip pulling 5th wheel the engine goes into power de-rate (limp) mode and check engine light comes on. 8 hour trip took 10 and I was sometimes only able to make 40 mph on interstate. Same deal on trip home (wasn't away long enough to have problem diagnosed and repaired). My dealership determined it was a pcv on fuel pump sticking. Had to replace entire fuel pump and it required cab removal! About $2800 total. Labor alone for cab removal and replacement is about 10 hours. Why on earth design a vehicle that requires cab removal for simple replacement of a critical part?
