long time reader but infrequent poster here. original owner. 2015 Ram 1500 ED 102,530 miles. GDE tuned since about 20K miles. I have some questions hoping someone here can answer.

Wife and I were planning a road trip so I took the truck in for oil service and fuel filter. Truck had 7099 miles since last oil change and about 10K on the fuel filter. (I have always used Mopar filters for everything.) The truck was running fine when I drove it for service. However after the service was performed it would not start - they had to push it out of the bay. Diagnosis is a failed high pressure fuel pump. Service manager says they opened star case on this and parts are "on order" but I can't get any timeline on when they will arrive.. I know there is an open recall on this failure and according to the recall notice "parts are not yet available". My truck is up to date on all other recalls.

I sent an oil sample to Blackstone before taking the truck in for service. The report came back stating "the fuel dilution from your last sample has cleared right up, leaving you with another perfect report for your Ram. Metals look great... Nothing here looks problematic. No coolant, water, or excess dirt was found. The low insolubles reading speaks of good combustion and oil filtration. Nice report."

Does anyone know how changing the oil, filter and fuel filter can cause this failure? Has anyone received a new fuel pump under the recall yet? And are there now additional issues this failure will create in the fuel system?

Thanks in advance for any insights on this.

It's possible they didn't prime the HPFP prior to starting after he fuel filter change. Seems like they did something wrong. I don't think its coincidental.

I wonder whether it was a diesel tech or a lube tech that serviced the Eco? I suspect a lube tech.

Probably just jumped in and "Cranked Away "

Pull the new fuel filter and look for metal. If they still have the old filter, look at it too. Even if it didn't fire, the fuel should have still flowed through the system.

Here is your answer; These CP4 pumps are junk. Nothing more to read into.

And they all wonder why I change my own oil and filters. Lube jockeys are scary. I had the dealer in Wasilla, Alaska fix the tailgate deal for my 2017 Ecodiesel, while there I had them rotate the tires. Big mistake.

That same day I received the cord for the block heater, and needed to take off the right front tire.

HOLY SHIT, did king kong put those lugs on? Did they break out the 1 inch drive air hammer? I broke my 1/2 inch drive breaker bar, no kidding, taking those off. Man if I would of had a flat somewhere out there, there would of been no way to take those lug nuts off with that stupid lug wrench under the seat. Don't they train those guys? Do they know what a torque wrench is for?

Of course I went around and loosened and retightened the lugs correctly. I was so pissed I could of chewed them off like a beaver.

I was lucky where we're at in this middle of the desert rv park. I asked the owner if I could change my oil. No problem, just do it over where the county parks their equipment at night, where the other oil stains are. Pretty cool deal, not very many rv parks let you service your diesel truck on site. I did not want to go to the dealer, but I was near out of miles and it was time.

Did I say I distrust dealer mechanics?

Good luck PFV, I'm on week 2 of zero call backs and zero answers. Other than that the warranty "may" cover towing but I would have to submit it to FCA.

The 120,000 mile AFE warranty sounded great, but ...

Piss-poor answer. HPFP failure is rare and the failure rate is low. It's pretty coincidental that the issue happened at the exact time of the service. The odds of that happening are astronomically low.

Call it what you want, I know of several of these trucks and many GM and Ford that have failed miserably due to CP4 injection pump glitter bomb episodes. You don't have to like it but it's true. There wouldn't be a recall if the failure of these pumps were actually "rare and the failure rate is low" as you say. We have no idea how many but it seems every day they pop up. I'll just keep my fingers crossed and hope mine runs until the parts come available for the repairs to be made and hope its a CP3 or the like.

It's really easy!

Your VW TDI and mine along with @Ecosparky are not exactly the joy of granola folks but the TDI's are sure fun little oil burners I always make sure to keep feeding the HPFP hot shots everyday.

You can't lump cp4's from all manufacturers together as some don't use hardened internals.

Not as much fun as it was before the AEM fix. My wife says all the time that she's happy we did not do that to her Golf. We just took the money for that one.

If you tune it you'll unleash a beast. I had no idea there is a global community of enthusiasts. I wonder if @Ecosparky has his performance focused. My ex-neighbor had close to 300k before he moved.

Not sure what you're implying here but all of the CP3.x and CP4.x pumps are made by Bosch. I would be very surprised if they were using different internal treatments for different manufacturers. At least in the case of GM, they were/are running their own pumps.

Hardened internals don't keep the roller/piston from turning sideways.....thats the big failure mechanism.

There not running there own pumps GM they switched from Bosch to Denso for fuel parts.

Yep, had to get something more reliable since Bosch wouldn't improve the pump to acceptable standards of durability.

Actually its as much gm fault as bosch since they refused to a in tank lift pump. After switching to denso gm started using in tank lift pumps.
