bad injection pump?
I have a 2001 2500 4x4. A week ago i noticed the truck cutting out, i was accelerating moderately and only on level one.(edge jwa cts hot unlock) The sputter got worse as i turned the programmer up. I have a 150 airdog, and i changed the fuel filters shortly after. When i changed the fuel filters i checked to see if it made a difference. I put the truck in 4x4 and boosted it up in reverse and got tons of black smoke. I then tried it in drive and just got a little bit of black smoke (I don't care about how much smoke my truck makes, just using smoke as a reference) Going down the road and accelerating i can still feel it cutting out, and if i'm just cruising with the edge turned to 6 it sometimes goes crazy cutting in and out just as fast as one can think. i tried unplugging the edge from the dlc and it still seemed to cut out. I just today replaced my batteries, one cable end, and checked the pump wire where i tapped into it with the edge(it appears to be fine,i even unplugged the edge wire from it and plugged it back in). Also all the grounds appear to be fine. I did pull a p1689 and a p1693 and cleared them but they have not came back yet.(approximately 100 miles) I know most people will say that it is the pump because of the p1689, which is unfortunately probably right, but i dont know because of the fact that i have no mil and the truck seems to be making the power it should when in reverse. has anyone had a similar problem or extensive knowledge on this sort of problem? any and all knowledgeable responses would be greatly appreciated. thanks!

It does tap into the fuel wire. I just turned my quad to zero and left the smarty on 8 and it.worked itself out. I thought mine was because of.my bigger injectors. Are you still running stock ones? have you checked for codes? Its hard to smoke my truck in reverse unless I boost it up and launch it .

yes i still have stock injectors... another problem i noticed is that i"m having some problems with my oil psi gauge on the cts only. i have talked to edge and will talk to them tomorrow again but i'm wondering if its not just a problem with my progammer? I turned my programmer to 0 (stock) and i haven't noticed any problems during the 60 miles i have put on it since(similar to your symptoms) have you since turned your quad back above stock? and if so does the problem consistently persist?

I've checked for codes and the ones i posted about in the original posting (only ones ever recovered) have not reappeared. Before the problem arrived i was able to blow limitless black smoke when placing the transfer case in 4wd and placing the transmission in any forward or reverse gear, stepping on the brake and pressing the loud pedal. now it is only in reverse when i can get it to smoke excessively
