Injector pump failure.....common?

Yesterday, after my wife picked up the kids from daycare the Jeep decided to stall at a traffic light in a very busy intersection. No light or warnings, just died. She tried to restart to no avail. Got it towed to dealer.

Dealer called today and found the injector pump grenaded and sent metal shavings throughout the fuel system.

Dealer is replacing pump and fuel system under warranty and should be ready in a couple of days.

The Bosch High Pressure Fuel Pumps (HPFP) are know to have issues in the VW TDI's (I think I read that the ED uses a Bosch pump as well). Many believe it is due to the lower lubrication in the ultra-low sulfur diesel we have in North America. Same symptoms / outcome as you describe.

I rarely put additive in my 2006 Duramax, I do run some Power Service through it every once in awhile. It has the cp3 pump and is the year before the DPF emissions crap. I'm going to drive it till the wheels fall off.

I have never ran any additive in the Jeep. The injection pump should be built to run the 500ppm ULSD without failure, but that's not the case. The CP3 pump which was designed to run the "DIRTY" diesel fuel is doing fine, go figure.......

Same here.. I have a 2004 2500 Cummins that I've had since new.... No DPF/No SCR and NO cat. Just straight pipe out with an aftermarket muffler.
Change oil with T6 and fuel filter once a year, a little power service once in a while and it is just flawless. I would like to have a newer truck, but this one has been so good, I don't think I could ever get one good enough to replace it with....
:D

HPFP failures are pretty rare on this forum. HPFP failures on my BMW 335 engine was almost total fleet because of incompatible materials used by Bosch and American fuel.

My Super Duty never had issue one with low sulfur fuel but I would use Stanadyne additive once in a while. At 179K miles running strong.

There are many JGC drivers with over 150K miles and have seen no reports of HPFP failures so I think the reliability must be pretty good...

From my experience with VW TDI's and BMW diesels, I run Stanadyne Performance Additive and Lubricity Additive at every fill. There is a wear scar rating on these HPFP's from Bosch and much of the low-quality diesel (compared to Europe diesel) exceeds that rating, meaning that a lubricity additive is needed. I don't run these additives expecting to see an increase in mileage or power (my BMW 335d soaked up the Amsoil cetane boost I used to use on it,) I run them to protect my diesel injectors and HPFP in particular.

Got a call from Dealership, the pump is on backorder. Service Rep will not know till Wednesday if or when pump will be available. GREAT

I feel like I should not have to run fuel additive in every tank to keep the fuel system happy and working. I will run additive to help clean the system every now and then. Bosch should make a pump that is built to accept the diesel fuel we have and not have to rely on additives to keep their pumps working.

If Jeep wants to supply me with a lifetime supply of fuel additive, then I will use in every tank.

I see no evidence that your pump failure is caused by low sulfur fuel. If that was the case there would be hundreds or maybe thousands of pump failures (ala BMW Bosch 3.0 twin turbo engine).
Remember that Bosch and other manufacturers are subcontractors to engine manufacturers and subject to having failures at times.

How is it that there are many out there in the 150K miles range with no fuel pump issues? I think Bosch learned their lesson regarding fuel comparability else they would be dropped for other manufacturers if they didn't.

I don't think Jeep will be able to tell the cause of the failure but maybe FCA can if analysis is done.

Please post what they tell you but you are right we should not have to use Stanadyne or other additive to keep our fuel system happy.....

Adding a 3.00-5.00 shot of additive each tank is counter productive financially and effort-wise to the economy of the EcoD. Never have added it and never will...Change filters every 20-25K, Stay way from Bio Diesel if possible....and like the commercial says " For every thing else there is warranty and Maxcare"

Stbentoak,
Each to their own mate. About 50 percent of our mileage is towing our travel trailer.
The PSD also has a Cetane boost component and with my experience over 36k miles now, I can actually tell when I have the PSD in the tank and it is more noticeable when towing.

I also use a progressive maintenance schedule on all our vehicles and change oil and all filters regularly.

I have Maxcare on ours but having vehicle issues when towing a travel trailer becomes way more complicated when 1000 miles from home!

Got a call from dealership.....

Service rep: "We got the Jeep running"
Me: "Great, when can we pick it up?"
SR: "We have another problem"
Me: "WHAT!!???"
SR: "It runs, but has a knock in the engine. We are going to have to replace the engine."
ME: SMH

They are going to tear into it and send pics off to get approval. Hopefully, I should know more information tomorrow. I never noticed an engine knock besides the diesel noise, but I never had it next to another Eco. I did get an oil sample on the engine a few weeks ago and the report did note high wear metals, chrome (rings) and iron (steel) especially.

Well, instead of getting a new fuel system we are getting a new engine. This is (was) my wife's daily driver, and I can not count how many times it has been in the shop. Very frustrating!

I don't know if I should try and get Jeep to buy it back, or drive it till warranty runs out.

If anyone is interested in the Oil Report, I can post it.

I bought a maintenance service plan through the purchasing dealership. I always do my own maintenance on vehicles, but the only reason I bought the maintenance plan because it was cheaper than doing it myself, plus for having a paper trail.

I got the oil report to make sure the dealer put the correct oil in the Jeep. I heard this dealership can be shady when it comes to Eco oil changes. According to the report they put in 5w-40. However, I do not know what they put in the last three oil changes.


Now, the Jeep is at a different dealership for service.

Update.....

New fuel system!
Text Font Paper Document Newsprint


The Jeep didn't need new engine. Service found the "knocking" noise as an injector not set properly into the head. The noise was (still is, I'll get to this) combustion pressure escaping around injector seal.

My wife got the Jeep back 3/1, Wednesday from the dealer and noticed a smell in the cab. I thought it might be from seating in the shop and outside at the dealer for 2.5 weeks. She told me Saturday the smell is still there. I drove it and noticed an exhaust smell coming out of the vents.

I let it run in the driveway and smelled exhaust coming out between hood and windshield on passenger side next to cab vent intake. Took engine cover and sound foam off passenger side engine and noticed....

Blow-by on head. And also a puddle of fuel around base on injector and on head. I wiped it with a paper towel

Back to the dealer Monday. I hate to diagnose problems that SHOULD be caught before we picked up the Jeep.
