High Pressure Fuel Pump

Just bought a 2008 SD 350 6.4. Engine light came on so took it to Ford dealer.
Says the light indicates the HP fuel pump. Further states its a cab off job at $3100.00. Seems to drive ok at the moment but I'm thinking it could die on the road at any time. Any comments (options) would be welcomed.

Did they say what the code was? Some dtcs (po88,po87, etc) do point primarily to the pump, some could be generated by wiring issues. Are you out of warranty? If so, it is easier to pull the cab for the high pressure pump (but it can be done cab on).

Thanks, will ask for the exact code number. Truck has 114,000 so no warranty.
This maybe another common issue on this truck.

Thank you so much Blacksnapon for all you info. Exactly what I needed. Bought the truck from a dealer with this issue so this gives me what I needed to know to talk to him about. Also, ever heard complaints after recall 11B23, reprogrammed PCM?

That reflash sets a dtc when it notices any of a number of issues. If the flash wasnt done, these issues would continue unabated. Don't think of it as problems with the flash, think of it as a problem found that otherwise wouldn't be noticed.

Thanks, I'm not having any other issues but the truck did kind of (power down) on me once after the reflash. I guess related to the HPFP problem.

update

The pump replacement was a "leftover" from Navistar. Ford has a reflash that "widens" the perameters on the volume control valve, and pressure control valve. These two valves are what fails, or get out of specs. Have your dealer update the pcm before replacing the pump.
