Lift Pumps and Injectors

[jimnance]

I saw my local Dodge Service Advisor today about a couple of minor issues with my '03. I've gotten to know him pretty well, and I ask him about an '04. 5 dually that's been in the service area for over a week. I ask why.



He replies "injectors". It seems that one hole was not putting out power. After switching injectors to verify the problem another injector starts leaking down causing severe smoke on start up. The dealer is doing battle with DCA to get the injectors replaced. The service rep says " They (Dodge) don't think they have an injector problem, huh".



So far he hasn't seen much trouble on the '03's for some reason, but many more problems on the '04. 5's and '05's.



As an aside, he says I should get a fuel pressure guage for my '03. In the last few months he's seen two '03's and an '04. 5 in with injection pump failure caused by lift pump failure. This seems to dispell the myth that the new injector pump is OK with a lift pump failure, and that they have gotten a handle on the lift pump problem. Apparently not.



I was quite surprised by his frank comments which tells me he is getting agravated with DCA dodging warrantee issues.

And I was looking at a 2005. Now you tell me theres fuel system problems? What does anybody else know about this? Are these stock trucks or do they have fueling boxes?

Naturally, they aren't bringing the trucks back to the dealers with fueling boxes. However, from the way the one I saw was outfitted, I'd guess that he had one.

The CP-3 does have it's own internal "lift" pump, of sorts (output pressure on it is around 180 psi). If I won the lottery I'd love to try removing the Dodge lift pump assembly completely and seeing if the CP-3 could suck fuel from the tank on its own. It would be an interesting experiment.

i bet you wouldn't... you'd just have more $$$ to play with for your fuel delievery projects... i can see it now... pto driven piston type fuel pump with -16 inlet lines and -12 pressure lines through more filters than one can count...

rbettele,



I've read posts that the Dmax uses the same CP3 without a lift pump. But, it's suppose to have larger fuel lines.

I've posted this before, my LP went out at 198,500 mi. , and I drove it 1377 mi. before it quit, and 488 of those was with a 36' 5er in tow. The tech. said it quit because the veins(sp?) siezed in the LP, and stopped the fuel flow thru it. 214K on it now and the same VP-3. I had one of Quadzilla's 1st. 100hp boxes on it for 80K, installed it at about 22K,then went with the Edge Juice w/attitude, its still on with a BD DL, and is running fine.

Mine quit at work yesterday, towed in to dealer (behind a GMC gasser towtruck ) Dealer just called -said lift pump toast. Should I be concerned with cp-3 damage? First symptom was a very brief loss of power (like go pedal didnt do anything) then ran fine into work (only 2 miles from where I first noticed) shut it down, 2 hours later started fine, drove around back of the shop, got out left running - it quit as I was walking away It started then quit after 1-2 sec and would not restart after that. Sorry for rambling , Im just curious what else to expect after waiting for lift pump to come in friday - Kevin

Sad to hear. I have a 1999 with 63000 miles on it Four lift pumps and two injector pumps. I FEEL YOUR PAIN

BTW, I love my CTD. My post was not meant to knock the CTD, mearly to point out that there may be a weak link or two. I still wouldn't trade either one of my CTD's for two Ferds or D-Max's.



I do find that Dodge is sometimes a little reluctant to authorize warrantee work, especially the expensive stuff like injectors. .



My '99 went 95,000 miles on it's first lift pump. I finally changed it as a preventive maintenance item. It was about out of it's warrantee, and I didn't want to buy a VP-44 if it was getting ready to quit.

I think there needs to be a correction. Dodge is not reluctant to authorize warranty work, Dodge is reluctant to authorize parts until the technician has PROPERLY DIAGNOSED the problem. Granted some problems are harder to diagnose than others, but every dealer has the opportunity to attend the proper training on the common rail engine, and every dealer has the special tools required to test and repair.

In our area, all Dodge dealers were trained on the CRTD engine via a self study CRTD theory and operation, and then three live days of training at the training center on CRFI and engine overhaul procedures. That was two years ago or so, and some dealers may not have the trained tech still employed, but as far as I know, the training is available on an as needed basis.

One note on the '05. The lift pump has been moved to the tank starting in 2005. On '04. 5 or earlier, the lift pump is still next to the fuel filter assembly. Many members have relocated their stock lift pump near the tank with good results from a reliability standpoint.



I don't know if this helps you or not.
