2nd Generation Dodge 24 Valve Powertrain

Send my ecm off to auto computer specialist and got the email this morning the found shorts in my lift pump circuit, app pedal & cpu. Truck has a fass 100 on it which seems to be working fine( it's running and it's pushing fuel to the vp) & I'm replacing the apps With one from genos garage(I stuck a junky Amazon knock off on it to try to get me by, didn't work so don't waste your time) anyone think there's any thing to worry about with the lift pump circuit? 98.5 24v

Looks like I hashed my engine. I'm not finding many good used ones, so considering a reman unit. Are there any decent reman companies out there? Checked Jasper and their prices are pretty high. I really can't justify $10k to put an engine in a 20 year old truck that's only worth about $10k......

Bout time to reset valve lash and I haven't found anyone's previous post about what they recommend. I am setting the lash for my new stock motor for my 99 at .10 and .20, but is there any recommendations for durations of a motor with 100hp injectors and a quad with wiretap? Anything helps, thank you!

Hey i am new here i am in the middle of swapping my injectors from 7x.012 to stock injectors since i dont think i need that big of injectors on a stock engine and its been having hard start issues the truck has 205k miles and 1,3,4, and 6 Connector tubes look like this and i havnt seen any pictures of them that look this bad just wondering if this is normal? Truck is 01 2500 6spd HO

Hi guys, had a bit of a weird experience with my grid heater this past winter thought Id share incase someone else is having trouble. The intake heater wasn't working, the wait to start light would come on and cycle like it should but the volt meter never showed a drop. Checked the hot side of the relay, it showed 12 volts. Cycle the heater on no voltage at the heater terminals. Must be the relay. Replaced with new, same outcome. Took the leads off at the heater to check resistance, checked ok. Cycled the heater again and the leads showed 12v when they were not connected to anything. Long story short I needed to clean the lead at the battery terminal. Apparently it…

I installed some coolers from Genos garage. Now days there are a couple options, one is Fast Cooler that is a spacer that uses your original PTO cover, and the other is by Trans Cooler that is one piece and has fins inside. The fast cooler gives you 2 quarts extra when you install both and the Trans Cool only gives you 1 extra quart because of the fins inside taking up space that could be oil. I choose the Trans-cool version for 2 reason: 1: only one gasket to leak from instead of 2 per cooler. And 2: I thought the concept of having heat sinks inside may pull more heat to the outside. Who knows if it will and I might have burned myself out of an extra quart of cooling. Be…

Hello all, this is my first post here on the forum. I've scoured this forum as well as a few others for existing diagnosis and can't seem to find a sure answer for my problem. I just purchased a 2000 Dodge 2500 24V that has had a NV4500 swapped in. Everything, but the cruise control, functions as it should, however, the check engine light is on due to the PCM still searching for the Auto tranny. Being that it won't pass CA emissions testing with the engine light I could greatly use help determining the simplest solution to my problem. I do have a Smarty programmer for the truck and the PO tried their "manual recovery" software to no avail...apparently he was told this onl…

If my truck sits for a couple days I get surging and erratic idle when I first start it. Fass seems to show the proper fuel pressure? Leaking injectors?

Hello everyone, If you look at my sig, you will see I don't have a normal Dodge Cummins truck. I have all the looks of an old Ford, the power of a 24v, and the electrical gremlins of a shoehorned harness. My stubborn side has finally given in to ask for diagnosis help because it seems there are many different things that could be causing the issues I'm experiencing. Context: To make a long, complicated story as condensed as I can, I sold my truck because I'm moving to Germany in a few months and it would NOT fit on the roads there. I sold it to a kid on Fort Bragg and I should have known better. Zero mechanical experience but swore up and down h…

i have a xzt xzillerator tuner trying to re flash but win 10 wont recognize the tuner does anyone know a work around for this without sending it back to quadzilla i dont have access to a pc with xp

Had a nasty belt squeal for a while. Kinda embarrassing to drive since it was louder than the engine itself. I could spray water on it and it would quiet down so I figured it's the belt. Bought the one in the picture from Rock Auto and the squeal is gone! Even the signature Cummins chirp on shutdown has gone away. Time will tell how it holds up. Just wanted to share for those fighting a squeal.

I changed them early at 30k miles. Yea I need to leave them in longer. I'm changing too early at 30k miles. Factory rate 15k miles is like fresh out the box yet. Running good ol' petroleum diesel. Mostly from Maverik Fuel Stations here on the west side.

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
