6.4L Power Stroke Diesel High-Pressure Fuel Pump Concerns | Ford Tech Talk

The 6.4L Diesel is the first Ford engine to feature a high-pressure fuel pump, mounted underhood, in addition to a low-pressure fuel pump, located within the Horizontal Fuel Conditioning Module, or HFCM.

If the vehicle has a crank/no-start or an extended crank situation, it could be because the high-pressure fuel pump isn’t getting enough fuel supply. In this Ford Tech Talk, we’ll show you what to check for and how to diagnose the situation

We’ll also take a look at Motorcraft remanufactured fuel injectors and explain why they’re the optimal choice for your Ford or Lincoln vehicle.

Ford should give us 6.4 owners new trucks free of charge because they knowingly sold us a defective product in the first place. Nothing but heartache with mine. I can't believe there hasn't been a class action lawsuit on these trucks yet.

Can you bench test the High Pressure fuel Pump?

[billnorris]

Is the high pressure fuel pump the same in F550 as aF350

When removing the back banjo bolt to check defense is there a universal banjo bolt with a test valve??? To monitor both ports at the same time? Are just remove it to see the defense when hooked to the front test valve? Asking for greenhorns education!

“...if you own a 6.4, Ford recommends you should replace the entire truck instead of fixing the hundreds of problems that occur on these models.” Lol

7.3 made it difficult for Ford to make money, so they made JUNK engines after so that they could recover from the Loses from the Great 7.3. I will never buy a Ford Diesel again. My 2008 is my last. My 7.3 has been in a shop 2 times, 1-for rusting in fuel tank & 2- water pump and it has over 300K. My 08 has been in & out (approx. 5 times) of shops in the last 6 years with a Lose of $8K. Twice because of the High Pressure Fuel Pump in 4 years!! Time to sell it and eat my loses. 7.3 still running strong too.

P0088 tells me to replace fuel pressure sensor.

[adamkorzon]

So basically you need a new pump in short.

[mattbergseid]

where, besides under the hood have they been mounting the high pressure fuel pump? all diesels require a high pressure pump, ALL!

I assume This is post mercury discontinuation
