Jimmy Lew,

Since your engine won't go over 2000 rpm's, I wonder if your fuel filter could be clogged? The ULSD has a "solvent-like" effect, cleaning up the fuel lines & holding tanks of the fuel distributors. A lot of the "junk" form those lines & tanks could have got into your trucks fuel tank & filter.

Don't know if that's the problem but, something to check out.

One of the things that keeps the injector tips clean is towing heavy or, basically, running the engines hard.

I we can keep our injection pumps lubed, maybe the Ultralow sulfur will be better for our injectors.

 

Hey guys,
Thanks for all the suggestions. I guess the next step is to pull the injectors and take a look at them. I have a new FASS fuel system so all the filters are fresh. I do pull at least 7,000 pounds every month or so. I have a trip planned to NJ and New Mexico so I will plan on putting my foot in it and using plenty of injector cleaner.
FYI, I filed a fraudulent charge for the installation of the "invisible" Lift Pump and Friday that amount of money showed up in my account. Now just have to make sure that this didn't screw something up?

 

Do you know why the ULSD has a "solvent-like" effect? That's the first I'd heard of it...

 

I was wondering how long it took to get satisfaction... when did the dealer rob you, and when did you file the claim? Who did you file with?

Also, could you tell us which dealership it was, so we can avoid it like the plague?

 

Hey Guys,
I filed with my credit union about 2 weeks ago because I paid for the service with my Visa Check Card. I am not sure if Visa has reimbursed me or the dealership had to fork over the cash. I hate slinging mud but the dealership was Bob Carver's Cars and Trucks in Mena Arkansas. My first mistake was not buying a service manual for this truck when I bought it, the Second was having it towed to this dealership. Hope this helps.

 

You're right about the service manual; the first thing I buy besides fuel for a new vehicle is the factory service manual, as soon as it's available... it's the best first place to put your $.

Thanks for the info.

 

Hey All,
Just wanted to give everyone an update on the saga of the "invisible" Lift Pump. I filed a complaint with the Arkansas BBB and since the dealership would not consent to arbitration the closed the case administratively. My bank has deposited the money back into my account conditionally as thier investigation continues. I am compiling a reply to the Arkansas Distric Attorneys office and will be sending that back this week.

I need some help from you!! Part of the dealerships defense has been that the truck will not run without a lift pump or a working lift pump. Anywone that has had an experience with driving their Gen3 Dodge with a Common Rail Pump with either a non-working lift pump or without a lift pump at all can you send me a message so I can compile your responses and send them with my rebuttal to the District Attorneys Office.

Thanks,

 

Don't know if this will help you are not......but I think the Duramax uses the same CP3 injection pumps and they don't have lift pumps at all. The CP3 will suck fuel once it is primed. And, ours won't because if the lift pump is in place the CP3 will not suck fuel through the bad lift pump. In your case there was no lift pump (right?) so there was no restriction to stop the CP3 from sucking the fuel it needed to run.

 

dumb question, but did you happen to take any pictures when you dropped the tank? Unfortunatly when my lift pump died it did not restart or run and I was doing 120km/hr(72m/hr) when it happened.

 

Took pictures of what I removed from the tank. They just state they do not know where I got the part from as it is no longer available from Dodge. Douh, It's the original one.
I wonder if I can find documentation on the Duramax? Are you a chevy mechanic? Need all the ammunition I can get if I am going to take them to small claims court in Arkansas.....about 300 miles away.

 

Jimmy, If that question is for me..........No, Im sorry I am no mechanic. I have just heard others mention that the Duramax, in stock form, has no lift pump. The CP3 will suck fuel all by itself. Supposedly ours will too if it doesn't have a restriction (ie..dead lift pump).

Hopefully somebody on here a little more knowledgeable about the Dmax can help you with that. Or you might ask that question on www.TheDieselPlace.com

 

My Ex-Brother in Law is a chevy mechanic. I talked to him last night and he confirmed that the duramax does not have a lift pump. He is going to confirm that the pump the Dmax uses is in fact a CP3. I will let you know after I know for sure.

 

The Duramax pump is a CP3, just a different model. It was designed from the start to not use an LP so the low pressure pump, lines, etc, are different sizes to compensate for having to draw from the tank. BTW, it didn't work that well either as there are multiple solutions to put electric pumps inline to boost fuel delivery.

As for the Cummins setup, it came with an LP for a reason. It needs an LP to function correctly. Period. In so many ways this idiot dealer trying to argue it doesn't need a pump is soooo wrong and it is hard to visualize a defense they could mount for failing to install a pump that is part of a DC approved retrofit.

 

no_6_oh_no,
The "idiot dealer" is saying that they installed an in tank pump and charged me accordingly. After experiencing poor performance I purchased a FASS system. When I pulled the tank (6 weeks later)to install a draw tube (to bypass the intank LP) the original module was still in the tank, the module without a lift pump. They are argueing that they installed it when they didn't and their biggest defense is that the truck wouldn't run without a lift pump.
