High Pressure Fuel Pump Failure at 3,800 miles

[Cummins12V98]

How can you say they look dry? They’re laying in fuel...

he is getting old.

May have been a bad call, but it is done. My dad has an eco diesel and it has been great, maybe he got lucky. They basically matched the original sticker and traded me keys.

 

[gsbrockman]

Well......thanks for coming back to clarify everything.

So I have to ask, has anything changed with your truck requirements in the last 5 months? Seems like a very short timeframe to go from a HD to a LD.


That being said, the ‘18 I bought last year was 2.5 months old because the original owners needs changed so I know it happens. Really more curious that anything.

So is the 1500 a 2020? What trim level?

 

[R.Taylor]

Yep, wow that was fast....

Yeah they will be burying this one.

I'm betting corporate told the dealership to take care of it quick... Real quick.

I had considered a LD in December, but the incentives on the HD were really good. I really didn’t need it then, but have been driving one for 20 years. Haven’t needed it in a while.

2020 Limited

You should make them throw in the longest, lowest deductible Max Care warranty offered.

Not sure why they said months for parts, the pump, rail, connector tubes, and injectors are all available now or within the week. And although the CP4 failure rate is higher than CP3, it is still not ANYWHERE near as bad as some make it out to be.

Thanks sag2
I was hoping its not as doom and gloom as I was building it up in my mind to be. After watching the above vid my heart kinda sank a bit. Im just going to run it and not sweat it. im at about 10,000 miles right now and its fine.

I have a good relationship with the head of parts at my dealership (Lots of fresh and smoked king salmon work miracles), Next time I'm in I'll ask him how many HPFP pumps has he ordered for the service department for the 2019+ CTD's... I'd say CP4.2 but he only knows it as a HPFP . I'm also going to ask my service advisor of 12 years what exactly would be voided on my warranty if I changed the pump to a CP3. From what I understand... They can't void the entire warranty, Only what's modified OR damage caused from the said modification. FCA/Ram/Cummins all knew about the CP4.2 pump... They could have easily gone with a Denso pump . Since Cummins uses Bosch injectors I'm sure Cummins wanted to stay cozy with Bosch and stick with them even though the CP4 pump is not that great but pretty much works. I don't think FCA/Ram have any say on how Cummins builds it's long blocks with ancillaries. I think Cummins is the one to blame, My 2 cents.

It will be interesting to see what they say. Worst case convert to CP3 after warranty is gone.

I would say the entire fuel system, and possibly the ECM since you have a non-OEM piece of electronics on it.

Likely not worth it until the warranty is up.

I dont know why they caved so quickly on this failure from a dealer side, I would track that vin and see where it pops back up on the used car lot.

Sale is done you get paid for the warranty service where is the down side to the dealer.

Edit,,,, well now that they sold truck 1, fix truck 1, sell truck 2,,,,, some flaws in the above.

 

[Newsa]

Defective from production, 100%.

One of a thousand will see this failure.
That's why we have a warranty on them.

1 of 1000 will see their demise with 120,000 miles.

After 120,000 miles, we will likely see significantly more.

Time will tell, i don't believe in this.

Point 1 is, the fuel filtration is now up to the task from factory.
Point 2 is, Bosch permanently improves their products.

When Bosch refused to pay Edelbrock patent use fees for their technology to prevent the roller came follower from turning in the bore, they set the stage for this issue. Until they do something to prevent that for happening there will be early failures. I have not read where Bosch incorporated the after market by pass mod on the return fuel path either. So saying Bosch permanently improves their products does not hold much water on this side of the pond.

I'll agree on Point 1, but not Point 2. Bosch are money grubbers like all large corporations. As long as enough make it out of warranty, combined with what gets denied due to contamination, whether real or imaginary, they win either way. I have no blind faith in any company anymore, including Cummins.

 

[Ozymandias]

But you know that this CP4 pump runs in millions of European Diesel cars right?

It's the same with the injectors, you can not tell it that they are improved just from looking at them,they look the same.
But they aren't, metallurgy and other tiniest things changes and that not only once, permanently.

Only Martin could enlighten us more, because he has the ability to watch behind the scenes.

But I'm so tired to hear all the time the same old story from back a decade failings, that doesn't make sense at all.
We know nothing about the reasons for the premature failures there, and it is also an entirely different setup.

Many people here blame Ford and Chevy to build ****ty pickup that doesn't last - but all of a sudden they are the benchmark?
Come on.
