P088 HPFP Issue

[SoonerDS]

After driving my truck around for about 3 months with the P088 code and getting told that I had to have the High Pressure Fuel Pump replaced, I struck gold yesterday! Just happened to be at a far off dealership to purchase a new exhaust sensor and swung by the service manager's office to ask if their dealership required the removal of the cab for this repair. He then told me the good news. Ford released a new calibration last month that nine times out of 10, fixes this issue! If you are being told that you need a new pump, go see your dealership. $115.00 and I'm fixed! Didn't think to ask him if there was a TSB but I'm sure there is. Great job Ford....now you need to refund everyone that got scammed with having to pay $3500 bucks for a new pump!

And this is the flash code. 11B23

I highly doubt the P0088 tsb calibration fix will be a permanent solution.

11B23 has been out for a while. My truck had 11B23 and still had a bad HPFP.


Ford acknowledged some HPFP pumps were defective. An upgraded pump was released (updated HPFP changed p/n from rev A to rev B)

I was just talking to My best friend who happens to be a Shop foreman for a Ford dealership, since my 6.4 with 18K miles on it appears to be exhibiting the same wonderful problems that are on various forums. On a recent trip pulling a 4 place snowmobile trailer, the truck down shifted and fell flat on it's face, I could hardly get 60 MPH out of it. I am running a Tuner and DPF delete and even on a hot tune I didn't have any visible smoke with the throttle wide open.
He told me that in cold climates the wax may separate from the fuel when the temperatures drop low (around 0 or below) and plug the filter. This is common if the supplier mixes summer and winter blend, or in my case if the truck was filled last summer and only run off an on during the winter. The problem when this happens is not only the pump being starved for fuel, but also the injectors get damaged since they are lubed by the fuel as well. They will burn back and ruin the tips.
Flushing the system is basically a band aid cure, but hey if it works I will probably try it and i will guarantee that this truck will be for sale shortly after. It is ridiculous that you should have to spend $70-$100 for fuel filters every 5000 miles because the fuel system is junk!! I am already running synthetic oil, so I am into an oil change well over $100 every 7500 miles. The only reason I bought a diesel was for towing and I am finding that it has been the biggest mistake of my life. My understanding it that this is a lot of the reason Ford has severed ties with International. After the 6.0 and the 6.4, Ford cannot afford the negative publicity.
