Fuel Pump Went Out

[Roaminglost]

So recently I was driving down the highway, then boom truck shuts off. Coasting to the side and getting it towed to the dealer. Took 2 weeks for them to diagnose that the fuel lift pump went out, which made the injector pump to go out too. So currently waiting on ETA of when it will get fixed. But the pump that is needed is nationally back-ordered. SO now there is no ETA yet on when it'll be fixed.

Anyways my question is, has anyone experienced this yet on the ED?

Yours is the first I’ve heard of . It sucks that almost everything is on back order now .

i do have alot of miles on mine 44k and luckily still under warranty but yeah I'm hoping Monday I get a ETA

That sucks, and it was performing so well for you.

Sorry to hear of your fuel pump.
Thanks for posting and information.
First I heard of a fuel pump problem, September will be 3 years on the forum.

I was wondering what your "fill up" procedures are. My understanding is fuel pumps are cooled by the surrounding gasoline. I try to avoid a low tank but have run it to the "50 miles" to empty a few times in my 24K miles.

I had a similar issue with my wife's 1984 Celica (great car). Car stopped working on the NJ turnpike. Needed a tow off the TPK and then a tow over the bridge to NY. The mechanic was a shop teacher and had trouble diagnosing the problem. The pump appeared to be pumping BUT with not enough pressure. He kept the pump for his class. Between the 2 tows and mechanical work it was a tough $$$ hit.

Best of luck with the repairs, happy to hear covered under warranty.

FWIW...
I use diesel additives to increase lubricity. The US-spec ULSD fuel has less lubrication properties than the European fuels. That was an issue for Euro diesels when they first came to the US after ULSD became mandated.

I have no idea if the Ram fuel system benefits from diesel lubrication additives. I use them as insurance and because it's what I've done with all my diesels.

YMMV. (Assuming you're able to get mileage with a running engine...)

Good luck getting your truck back on the road.

(When this issue occurred with the VW engines, the entire fuel system would need to be replaced, from tank to injectors. Metal parts from the failed pumps would contaminate the lines. Everything needed to be replaced. Not sure if Ram has the same requirement.)

Honestly i never thought about the low tank and just filled up how ever but the truck was at 1/4 tank when it happened. so I'm not sure and it was 90 something degrees out when it went.

interesting you said this because i now have heard about the additives after the fact lol. My buddy informed me that the amsoil all in one diesel additive is where its at. and people that have been running this additive have had no issues with fuel like this.

Pretty sure the Manual specifically says no additives are needed though.

I am sure, but why not if it helps the longevity?

Will it affect the warranty?

Regen burns the fuel soot off, but not soot from additives, metals, and other materials that collect in the DPF which turn to ash and eventually plug the DPF. Additives will potentially not get regenerated (burned off) and cause faster DPF fill. Some additives have proven to be worse for lubricity than not using one.

That said, the HD diesel crowd probably has more running an additive (HSS and XPD are the two most popular) than not to protect the (reportedly) problematic CP4 injection pump in our trucks. Some of you may know that RAM used the CP4 in only 2019-2020 HD trucks and went back to a CP3 (CP-ISB21S3) pump for 21.

Which pump is used in the 2021 1500 ecodiesel?

Hmm doubt it, doesn't say you cant use it, just says its not needed.

Love the G-Class btw, like my fav car.

 

[Brutal_HO]

AFAIK, it's still the CP4.2 (CP4 2-piston), they just don't run it as hard as the Cummins setup.

Great vehicle, I have had it almost 8 years. It is built like a tank but it is time to move on. 11-12 MPG with premium and $1K-$3K everytime it goes to the shop get really old. If I won the lottery I would definitly would buy another one.

I've used Power Service DieselKleen in my VW.

I'm using Amsoil in the ecoDiesel. A 50/50 mix of cetane boost and injector clean. I bought a case of each, $300 total. I'm adding it at a rate of 10ml per gallon. (Doing the math, based on the rate I'm adding it to the fuel, and the mileage I'm seeing, this amount of additive will last me over 50,000 miles.)

Why 10ml per gallon? Because my 12oz. squeeze bottle is good for about 30 gallons. (Amsoil specs for 6 oz. per 30 gallon for my boost/cleaning.) 12 oz. is about 350ml on the bottle. So, based on how many gallons I fill up, I squirt about that much into the tank in ml. 12 gallons is 120ml. Or thereabouts. If the squeeze bottle had ounces, that would've made my life easier. Shrug.

I used to pour all kinds on things into the tank of of my 1990 W350 Cummins to lubricate the fuel system. Marvels mystery oil, Lucas fuel treatment, 2 stroke oil, 15W-40, whatever oil was in reach basically. Should have kept that beast (rust never sleeps unfortunately), 30 years plus and not one single problem with the motor or fuel system. That was before they ruined diesel engines with electronics and computers, oh well technology moves on

FWIW, I too used MMO (a mix of MMO and PS actually) until I found out MMO actually reduces lubricity per a popular "lab report"...

update: july eta on a glow plug thats holding my repair up....
