Any Dodge Cummins heads around ?
Just purchased a 2001 Dodge Ram 2500 Quad Cab 4X4 Cummins with 59,000 miles and in magnificent shape. I've driven a few of them and never noticed this before. While at highway speeds if i drop the hammer she has no power above 23-2500 rpm's. Its almost like its running out of gear, but if i back off throttle and let her shift outta 3rd and back into overdrive she'll pick up speed . I work for a dealer and drove a 99 Ram with the cummins and it pulled strong to redline. Any ideas would be appreciated.

there was a rear gear option in those years, do the two trucks have the same rears? Has the 30K trans maintenance been done? I had a 2001 with a diable puck, best truck I ever owned. Only problem I ever had was the trans and after the service it was perfect. Best truck I ever owned. sold it with 42K.

Re: Any Dodge Cummins heads around ?
i'm having a dealer we do business with look at it tomorrow AM. was told to have them check fuel pressure (may have a weak lift pump). i just installed an AFE stage 2 intake, with a 4inch mandrel bent exhaust from turbo back. i have the edge comp box under back seat not yet installed. dont wanna put it in til i get this condition taken care of. trans juice looks and smells fine ? unsure if it was ever service but i may have them do it tomorrow and also wanna look into shift kit as well...THANKS
PS- will also have them find out what rear is in it

call the dealer with the VIN and they can tell you over the phone what rear end is in it. Can also tell you if all the services have been done.
doesn't sound like a tranny issue to me....

i'll give you another for instance...if you take off from a light with pedal to floor, as soon as the rpms get into 2500 range it just falls on its face, which it also does as it runs through the gears. if i let off pedal and allow it to shift into over drive she'll continue to pick up speed

Sounds like the lift pump is going. Ck out the Turbo Diesel Registry on a search and they will have all the answers to your problems. It is a great site for the turbo diesels. Dwight

Re: Any Dodge Cummins heads around ?
I am wondering if it could be the beginning of the end of the injection pump?
Kirk, from what I'm told by many tuners and diesel tech's when the injection pump fails it stops all together with no signs.

Re: Any Dodge Cummins heads around ?
there are 2 pumps on these trucks...lift pump gets fuel to injection pump...the only reason the injection pumps go is fi the lift pump fails
