I have a 06 Dodge Cummings 2500. I took it to the dealer ship a couple of months ago because of a no start. They said all 6 injectors were bad and replaced the lift pump in the tank. Ever since I got it back, I only get about 13 MPG and the truck doesn't feel like the power is there. I was getting about 18 to 20 MPG before the no start. The dealer ship told me that was normal and the truck would straighten up. I took it in at about 53,000 miles and the odometer now reads 63,550 miles. The truck still acts the same. Any one have any advise? I'm new to this site.

 

rail pressure??

 

did you take it back? what did they say

 

Took it back and they say it will straighten up soon. Something doesn't seem right about the dealer ship. They told me an updated injector was used and thats why they relaced all injectors.

They say truck is fine. Figured MPG by miles to gallons and getting 12.8

 

I would maybe take it to a different shop and see what they say, it might be the CP3 pump too if the inj's and lift pump went out chances are good maybe the CP3 got what ever they got

 

I will try another dealer ship. Does any one know about the updated injectors for these trucks that they told me about.

 

 

I know nothing of updated injectors other than the one's for the 6.7L.

 

You should still have engine warranty, check your paperwork. Then if so go to a different stealership. Did you but the truck new? Is there a chance the guy you bought it from had the tips changed?
