Ok, guys thanks for all the responses. I'm attempting the w-t ground mod 1st however after looking at the pics for the procedure I'm kind of confused on the alternator side of the project there is a kind of junction block on the alternator that contains 4 wires (2 large and 2 small) on the 2 large I assume one is the power wire since it connects to the alternator + stud and the other is a ground that connects to the frame of the alternator. Now the small Guage (blue and green) wires are field winding wires I assume do I remove the whole thing if so how do I know where the small Guage blue and green wires go I didn't see anything dealing with it in the pics. Or am I just adding a 2nd charge lead to the aux battery.

Any advice on an aftermarket lift pump and what size I'm running a edge juice tuner and would like to use the towing settings haven't used it since I fried the injection pump Not positive on the location I was told by the mechanic that replaced the injection pump so I would assume it was on the block but I'll have to check tomorrow. Been looking at the reviews on the bd and fass 100 gph models With lots of opinions both ways I'm looking at around 360 hp max. Was also looking at some of the mechanical pumps as well but not sold on belt drive.

I've been keeping an eye on the fuel pressure religiously since I 1st got the truck about 9 years ago. When I 1st got it I turned up the tuner and cooked the injection pump the previous owner installed the tuner and didn't upgrade the lift pump unbenounced to me expensive lesson lol.( at 18 psi at idle and not under 10 psi off idle) I just learned of wt's ground mod today and will be doing that shortly. Alot of the posts I read on other forums led me to believe the apps sensor could be the problem. And yes I believe the apps sensor is oem. I bought the whole assy because I was told by the mfgr the voltage was preset and didn't need to adjust it. That was what the insert that came with the part said. Sounds like I need to do that and some ground cleaning work and maybe a lift pump. I've rebuilt just about everything on my power wagon but these modern diesels are much different critters. Thank you for your imput, still learning with the modern systems if it's got a carb I'm all over it but kinda lost on the others Any advice on an aftermarket lift pump and what size I'm running a edge juice tuner and would like to use the towing settings haven't used it since I fried the injection pump

Hi guys, I understand this topic has been beat to death but I have had the following issues with my 98 2500 24v. Over the last two years I have had random codes pop up with no performance problems (low voltage related to apps sensor) had them cleared 2x about a year apart. Did hours of research and the common thread seemed to be a failing apps sensor (no dead pedal up to this point) So i bought a new bell crank assy to have on hand in case. About a week ago it happened dead pedal, when I pulled to the side of the road it went away. So when I got home I replaced the bell crank/apps assy asap. Been driving it for a week without issues yesterday when I was decelerating to a stoplight it happened again for just s second. Any ideas (vp44 was replaced about 3 yrs ago still has stock lift pump as far as I know).
