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.

Very Good!..

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.

Hi with what equipment it diagnoses. Is it IDS?

thanks Ford... nice video.

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!

[@albertclarke132]

Can you bench test the High Pressure fuel Pump?

[@NBF1865]

If you realized what it takes to get pump off you wouldn't want to bench test it. Just replace pump if you got that far

[@albertclarke132]

@@NBF1865 Oh brother I know, they're rebuild able too. Can't get replacement parts either. I'd bench test a new one too, to check the seals not leaking from the rebuilder, how do I know they didn't f it up...... check everything its not fun pulling a cab especially without a 2 post hoist

[@natehawkins2910]

“...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

[@goodtalker]

I baby sat my F350 for ten years. At 70K miles, I purchased an extended warranty for $6,000 for 60K miles. Easily paid for itself. At 130K miles I attempted to purchase another extended warranty. Ford told me to kick rocks. Mechanically the truck was still solid, but computer and electrical problems were beginning to cause multiple head aches. It's a shame, but I got a divorce from Ford. In 2002 I got a divorce from Chevy. I also got a divorce from Dodge this year after my Rubicon spent two months in the shop for similar computer/electrical issues. TOYOTA HERE I COME.

[@ronmcgill1522]

Easy to say that just made sure do regularly maintenance on it good fuel and you'll get a lot of years out of the truck . Know some guys got over 500,000 on the 6.4 trucks

[@tommybragalone7943]

goodtalker should have got a 6.7 instead of a 6.4 lol

[@aaronisaacs3765]

165K and not a single mechanical issue outside of a coolant line. That's what happens when you push 600hp on stock components. Emission delete, Religious maintenance, Godly engine.

[@wcsoblake85]

Man, you had me laughing so damn hard! But, it's kinda true. I have spent $15K getting mine right. My mechanic took the cab off and did everything necessary to prevent the heads from separating again and replaced/upgraded a bunch of other stuff while the cab was off. Also deleting all the emissions bull crap helped mine run so much better. I went from 15mpg to 25-28mpg under normal driving but it is so hard not to spool up that turbo and scoot down the road. I am currently replacing my radiator with a Mishimoto one. The body bushings were worn out and it put stress on the radiator and it has to be replaced. I used to drive JDM cars and Mishimoto made some awesome stuff so I'm going to try their radiator on my truck.

P0088 tells me to replace fuel pressure sensor.

[@adamkorzon2972]

So basically you need a new pump in short.

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.

[@karlmcclellan5942]

It all about maintenance. I have 2 6.7 that come in with around 800k miles. Both have original pumps. If you maintain your 6.4 like a 7.3 no wonder your putting pumps in it nonstop. 7.3 have plenty of problems and they don't make enough power to hurt themselves. Your point is mute... But the 6.4 design went in the trash for a good reason.

[@benniebenson7131]

​@@karlmcclellan5942 I have a 2014 with the CP4 fuel pump. When I bought the truck I knew about the issues the CP4 fuel pump. I would change my fuel filter at no more than 15k miles and usually ever oil change. I also had selected stations I would buy diesel from. When on the road I only used Pilot or Loves truck stops and would plan my stops accordingly. On top of that I put Ford diesel treatment in at every fill up. When I hear people talk about lack of maintenance causing these fuel pump failures I boil over. There was nothing more I could have done to prevent the two fuel pump failures and complete fuel system replacements in 3 years I have had. The pump has a know design flaw with the plunger/roller turning in the sleeve that no maintenance will prevent. Ram used the CP4 in 2019 to 2021 and recognized the problem and has issue a recall in Jan 2022 to replace the CP4 with the CP3. When will Ford step up, do what right and follow suit.

[@karlmcclellan5942]

@@benniebenson7131 Boil over all you want. after 10 years in the industry i know what i see. Your acting live every truck has or will have pump failure. This is just simply not the case. 80% of the truck i work on still have the original pump. Most of these truck are over 170k and maintain their trucks. I change more short blocks under warranty then i change pumps. But if all you do is look for people complaining on the internet i could see how your view gets distorted from what the actual problem is.

[@benniebenson7131]

@@karlmcclellan5942 I understand your reply. But if 80% of the trucks you work on still have the original pump 20% have had pumps replaced. That is not a good track record and it kinda supports my point. Just wish Ford would accept responsibility for a low quality piece of equipment like Ram is doing. Either way thanks for your reply and you are right you can always find information on the internet to support what ever position you want to enforce.

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

Thats not true, at all
