#572 of 642 Cummins Diesel by felt May 30, 2009 (6:43 am)
I wonder what the future holds? With Chryslers cloudy situation, and the government pushing hard towards small vehicles, I suspect our used diesels may become more valuable. You will need the big power to haul a trailer load of horses, or hay, or a RV; small electric "green" vehicle surely will not handle the task. Has anyone read any predictions for the big Cummins future?
#573 of 642 running rough/help!!!!! by 2500beast Jun 02, 2009 (2:39 pm)
i have a 2003 dodge 2500 4x4 diesel. it had a slight engine miss so i took it to a friend of mine who works for dodge. he ran a test on it and said that injectors 3,4,6 were running low and needed to be replaced soon. so recently i took it to a dealer and had all 6 replaced so i would not have to worry about the others. when i went to pick it up now it runs worse than before. it runs rough at idle and while driving it and blows a little black smoke at idle. what could this be and how did they mess up my truck. i left it there and they still have not rechecked it.

#575 of 642 Cummins fuel pumps by partsman2k Jun 04, 2009 (12:42 pm)
Well I have learned alot about cummins engines and Dodge dealers. Dodge dealers know NOTHING about cummins engines. I had the "DEAD PETAL "issue, took it to a Dodge dealer for diaganoise and was told it was the injector pump. I had a gut feeling so I took it to a 2nd dodge dealer, they again told me it was the injector pump. They both used a "Snap on" code scanner. (wrong tool) I went ahead and installed a new injector pump. $1,150 later the truck was just as weak as it was before. I then talked to a man that owned a diesel shop and works on them for a living, told him my problem and he immedtaly told me what was wrong. I replaced the MAP sensor also known as the (boost sensor) and the truck runs fine. If you have a problem you cant figure out, take it somewhere that they can hook it up to a LAP TOP not a code scanner.

Replying to: kcram (Mar 01, 2009 5:23 pm) I just went through your situation TAKE IT TO A SHOP WHERE THEY CAN HOOK IT UP TO A .....LAP TOP..... a bad injector pump will make the "check engine" light come on and STAY ON.

Replying to: 2500beast (Jun 02, 2009 2:39 pm) LOL! It sounds like your injectors were upgraded.... that's a common complaint when someone adds bigger injector nozzles but the only thing I can think of that is wrong is that the guys didn't pop check the injectors. If they pop off at to low of a pressure they won't atomize the fuel correctly and burn the diesel completely... which usually results in a rough idle and smoke!

Replying to: davidlvg (Jun 06, 2009 5:23 pm) thanks but it was done at a dodge dealer and they are factory injectors, but as of today they still have not looked at it. still looking for answers may have to take it some where else
