cummins problem
hey guys i am new here and need some help i have a 99 dodge 2500 mega cab 4x4 with 24v. trans only has 200 miles and i just replaced engine. engine starts up and runs strong. but doesnt rev past 2000 with out cutting out and usually first take off going down the road it will go threw the gears and some times not. then when u stop and go to go again it wont shift from second to third. and engine cuts in and out. i am getting codes for injection pump not communicating with ecm , and a code for ecm and pcm not communicating, i have checked all fuses and grounds. can anyone help me please.

this is random but my buddy just went through the same thing and it turned out to be low battery voltage he had one battery that was down to 8 volts and his alternator was on its way out and was causing the computer to cut in and out .. hope that helps

My 97 had a similar problem, although it was not computerized, the fuel pressure at higher rpms would get cut down, when hitting 5th gear it would stop, just installed another lift pump, and it fixed the problem.

VP44
Try this, my 01 had the same code, basically its the VP44 death code however the fuel relay will kick the same code if it goes bad. Change the Fuel system relay, in the fuse block under hood. If that doesnt help sounds like your VP44 is shot.
