2nd Generation Dodge 24 Valve Powertrain

So, for the last few weeks my truck seems to be louder than normal. Almost sounds like a knocking but only hear it in lower RPM limits (less 1200 rpm). I don't know if its just me or not. I don't have any CEL on or any codes that I can see with my Bluetooth OBD2 scanner. I don't see any smoke and the truck runs good. I did start getting diesel at a different station (Chevron instead of Fred Meyer). Could it be a difference in diesel? Could it be colder weather? It does it with the Quad at 0, 2, 3 or up. It does it with the daily tune and the performance tune. I can really notice it at cruise with light throttle. Any suggestions. This is my first winter with th…

I was replacing my injectors yesterday and when I took the valve cover off one of the bolts ripped the insulation and that crap went everywhere. I know some fell into the engine and I tried to wipe what I could out by number 6. How screwed am I?

So I was driving around testing my new 7x.012 injectors and new quadzilla and my truck died. I tried restarting and it started right back up. Fuel pressure from my Fass seemed a little low (around 12 or or 13 psi) but otherwise everything seemed like it was working ok. I made a stop for about 20 min and when I got going again the truck died again 100 yards down the road and wouldn’t start. I noticed that the pump wasn’t cycling on key on/ starter bump so I had the truck towed back to my shop. When I tested the pump by putting 12v to it, it worked, so I replaced the relay with another but couldn’t get the pump to cycle. I then tested the ecm signal lead and I was only gett…

Evening all, I've been searching and trying things for awhile now, and still no luck. Long story.. I have a 99 24v 5.9l that I have swapped to a brand new rebuilt ppump from Scheid diesel, new Crazy Carls kit, with 0.093 lines and DFI SAC 7x0.010 injectors. air dog 4g 165, new sump. Initially I bought the ppump from a guy that needed to be rebuilt, but i installed the pump and was able to get the truck running. but then the Rack was sticking so i sent it out. Since i got it back I haven't been able to get the truck to run, 3 of the new fuel lines weren't seating properly so they were replaced. I bought a used Airdog 100, but replaced it wit…

Installed a new air dog and vp44 and decided to put a fuel pressure guage in my truck is it normal for fuel pressure to drop going up a hill.

So on my 2001 the water meth controler and manual boost gauge match right up. The iQuad shows 1psi when the other 2 are reading 5-6 psi it starts to read closer once I’m above 30 psi. Bad MAPS sensor? What do y’all think

New to the forum so not sure if anyone has asked this question yet, but I just bought the quadzilla adrenaline with iquadbt. It's flashed and installed but I can't for the life of me figure out how to tune it so I have some form of power off the bottom end, I mean I hit the gas at the light and it takes like 10seconds to get rolling...... Any help at all is appreciated, I'd hate to mess up my baby

Ok guys I had to replace my vp44 so I also bought a new airdog 150 lift pump. So my question is. My lift pump wire that comes off the ecm when the key is in the on position it’s only reading 8.9 volts. Will this be enough voltage to trigger my relay for my new lift pump. Or is my ecm bad. Again the key is in the on position not cracking

Hi, I'm new to this forum and I'm in search of a Wiring Diagram for a 2001 Dodge Cummings Ram. My current issue is that there is no power to both fuel pumps and the relay keeps clicking on and off. I can't find the power source, and I haven't found a bad fuse. Thank you, Tommy

Well I notice after changing my oil 2 weeks go that I had not had to add any which is unusual since I have a leaky rear main seal. Today I check the oil and sure enough now I have more oil. Took the valve cover off and ran engine. Sure enough there is fuel sitting around no 2 and when shut it off and look back there is nothing there. What ever is there has gone back down the between the injector and the bore and I think I see air bubbles around no 3.. So I restarted the engine and sure enough there is air bubbles and fuel around no 3 and 4. The best I can see no 1, 5, and 6 are fine. I stuck a q tip at the bore of all of them and came back with oil on 1,5,6 and fuel aroun…

This is my first post on here guys, I’m in dire need of your help. 8 days ago I had a rebuilt transmission with a shift kit and triple disc converter put in the truck; a mile into the test drive all gauges were lost. Inline Performance figured out that it was a bad PCM and put a new one in it. Today I had to run home for something and left the truck running in the driveway for no more than 10 minutes. When I came back out, no gauges we’re working but the tach, the odometer is reading No Bus and the transmission won’t shift out of 3rd unless manually done. Please give me ideas, I feel my case is different than a lot of other no bus threads on here seeing as I …

Alright so story is, was driving the truck one day stopped and shut it off came back out and turned it on absolutely no throttle sense whatsoever, figured it was a bad ebay tps so through the old one in that just mad the truck idle high, three the new one on worked great until a few days later it did the exact same thing as the other one so I decide to go to thouroughbred diesel to get a reputable apps and put it in and still absolutely no throttle response whatsoever as if the apps was completley disconnected, throws the following engine codes P1693 P0123 P0122 P0121 P0230 any ideas or help would be appreciated. Just goes back to idl…

Alright, so she's back at it again. Probably my fault this time. Any who, on the way back from North Dakota a few days ago, I was outside Pueblo when I heard what I can only describe as a bearing seizing. A loud squalling like noise that shook the truck, and I felt it through the shifter. It wasn't constant. Just a quick noise, then gone. After everything that's happened, I was on red alert. Turned off my stereo, and kept driving, listening. Found an off ramp, and pulled off to see if anything had froze, was leaking, etc. Nothing. So I jumped back on i25 and headed south. She did it again. Loud quick noise. At this point I prayed nothing seized up completely before I got …

Symptoms: No speedometer, odometer works, ABS and brake lights. No codes Replaced VSS sensor on diff, replaced speed sensor on transmission.

Pictured is the block numbers I just installed in my truck. I removed the infamous 53 block. After attempting to start with no luck.... I researched and found that the back of the cam gear with the newer block has a tone wheel where the original only had a notch. I'm in the process of swapping the cams out because I'm sure this is the reason for the no start. I would like to identify this block for future reference if anyone can help me out. 1998.5 ram 3500

So my front driveshaft came apart. Anyone have any idea how long they are right off the top of their head? I can order a new one($258) vs having one built ($650). Mine is too damaged to measure properly.

Hey All, I would like to find a simple, inexpensive and automated way to adjust when torque converter lockup occurs. I am not interested in off the shelf transmission controllers. I have an electronics and industrial automation background. I am interested in hearing ideas that pertain to a DIY install and long term reliability, as well as ease of use for someone else driving the truck. I have 3.54 gears and 35" tires. I'm fully aware what that means for my final drive ratio, and I'm not entertaining a regear at this time. Please don't suggest obvious large mechanical changes. The truck has a lockup switch, which I generally don't use. W…

So as it says, more weirdo readings on my quadzilla. The temperature was going up to 204°, then would go to -40,then back to 204. I figured my cts was junk, so I replaced it. Didn't pay much attention to it these three hell filled weeks with it. Well, I drove home to NM from North Dakota yesterday, and noticed it was still doing the same thing. Up to 204,then -40. Then back to 204. Is this normal? Or?

Left yesterday to go get a new trailer. And I'm not sure if this is a tuner issue or a truck issue. Codes on truck are for ABS only. When the truck is running 70 at 2k rpm with XZT on the 75hp mode it'll surge. I can drive it out with my foot and it'll go away below 1800rpm and above 2300 rpm. When cruise control is set it doesn't do it at all. When set to MPG mode it does it light surge and still have to play with throttle or set cruise to get rid of it. With switch to off its hard to tell when it surges. Now, with the trailer behind it and the switch to 75hp position, it surges when I'm going down a grade and try to keep my foo…

I've been having some problems with my AirDog. So I've decided to hardwire it with a toggle switch. But since it has the relay I don't know which wires go where. I know I can jump the yellow and red together to turn it on but what are the other two. Do I need to tie those into somewhere too?
