High Pressure Fuel Pump Failure at 3,800 miles

[silverjay]

Has anyone else had fuel pump problems? My HP pump failed on Sunday and pushed metal through the entire system. Dodge has directed the dealership to replace the fuel system and there are no parts available for 2-3 months. They refuse to discuss engine damage stating it is impossible for metal to get through the injectors. Attached is pic of the fuel pump the dealership sent me. They have an engine in stock with all the parts needed already on it, but refuse to put that in so far.

I have been told that the supplier for the fuel pump also supplies GM and is having major failure issues. I can’t verify that other than being told that.

Any similar experience/thoughts/guidance? Truck is 5 months old with 3,800 miles on it.

Fill you signature with truck info, makes it easier for people to answer. Sounds like you have the infamous CP4 failure that plagued all other manufactures that used it. 2019 HO and I think all 2020 went to CP4. 2018 and earlier were CP3.

Hmmm, I'm calling this fake news until seeing some paperwork from the dealer. Sounds like a possible rebel rouser to me.


If true..... I sure hope FCA jumps on it quick and retrofits everyone with a CP3 before getting a serious black eye.

Understand the skepticism. Below is the shop paper from the dealership it was initially towed to. The fuel pump issues came from someone at the dodge truck service department and as I said earlier I can not confirm. Was hoping to get more info here.

The picture in the dirt post was taken by the dealership and initially attached to the service report. The picture link no longer works, don’t know if that is because the diagnostic job is complete and it was transferred to another dealership for repair or for other purposes.

not a rebel rouser other than pissed my new truck is dead and no parts for 2-3 months. Thanks for any insight.

Same here. Great first post from a newly registered member. Most people joining here have a first post that coincides with their truck purchase.

When the picture is enlarged, looks like all these “fragments” are sure nice and dry....to have been ejected through the fuel system. Looks almost as dry as where @TFucili lives. Sorry........I iz calllllllling horse schitttttttttttt on the deal.

Guys, not sure how to convince you. This is my third dodge diesel and I have been a member on DTR since 2005. Not much help from over there on this issue. You can argue with the picture, but that is what the dodge dealer sent me and what prompted them to authorize a full fuel system replacement.

would particle from a CP4 get through the injectors or is their plan to stop at injector replacement good?

Above is all the paper I have right now. What else do you need? I will be at the dealership in a few hours.

In any event.....if it’s going to be two to three months for parts, that sounds like an immediate buy back / lemon law on day 31 or day 32 (to me).

All you have to do now is review your options based on your state of residency....and watch the clock tick down.

Okay Silver, Well if it's happened to you at 3634 miles then I'm already driving on borrowed time.... I have 7260 on my 2019. Did they do a fuel test? I believe they test the fuel to make sure you didn't put gas in it or have bad fuel (which then they would deny warranty work). Like Brock said.... If they have it for more than 30 days you can tell them to eat it. Nevada lemon law is the same as California.... 30 days in the shop and they own it. I would not want the truck back as they are simply going to replace it with the same exact pump, There have been no revisions to it since it's inception that would keep it from doing the same failure again, Audi, VW, Ford, Chevy have all used the CP4 and had somewhat very bad luck with that pump.... They all fail the same way except for the few that have exploded. Ask the dealership if they'll install a CP3 conversion kit (which are already available for the 2019+ Rams) and warrant it. If they say no.... Then start marking the days off the calendar.

As for particles getting past the injectors...... I've never heard of that as the tolerances are too tight for them to pass (at least ones big enough to do any significant damage). The parties clog the injectors and the engine can't get enough fuel so it shuts down or goes into limp mode.

I'm going to bet the dealership asks you to keep a tight lip on the issue or to not discuss it on the forums.

Thanks. I don’t know if they did a fuel test, they didn’t mention it. I appreciate the Lemon Law info, I didn’t realize the 30 day clause existed. The Nevada law does have a clause about the 30 days being extended for some qualifying issues. Looks like I am in for a 30 day wait regardless.

picking it up this afternoon. Took a few days for them to get a truck rather than a car.

Thanks, I will talk with them about that.

 

[Signal73]

I doubt much of anything got through your injectors, or anything sized that would cause damage anyways. The injector holes are smaller then a pin.

 

[silverjay]

No go on them doing the cp3 conversion.

Welcome to the TDR. Sorry that you have to put a flame suit on for this issue. New members don't deserve it.

Some others on here already know Cummins ignorantly screwed up by using a CP4 while ignoring the Proven Failures on other OEM's. You are likely just the start of a long list of failures on Cummins. It's sad for an engine with a better than other OEM's reliability reputation.

Lemon Law does allow for cash settlements. One can take said settlement and drop a CP3 conversion on their truck knowing the rest of the worthless warranty on the engine will be void. Worthless Warranty is waiting 2-3 months for parts! At least they haven't voided your warranty yet over bad fuel. You had better be looking up your fuel receipts because your insurance company and a gas station may be having an expensive conversation.

I am one of those who is equally critical of all OEM diesels when deserved and will say of the CP4 "I hate to say I told you so: Just doesn't cut it!" Long discussion here:
