2nd Generation Dodge 24 Valve Powertrain

I will be installing new injectors soon and I’ve read conflicting info regarding whether crossover tubes should be replaced at the same time. Proponents (including @dieselautopower) of changing them out say the risk of fuel leaks is much less if they are changed out. Those who say changing them is not necessary advise that if they are correctly installed and aligned with the injector, and have a properly installed o-ring, leak potential is minimal. What is the prevailing opinion here regarding changing the feed tubes? If I change them out, is there any reason to go with anything other than these? https://www.dieselautopower.com/bo…

Currently when I turn the key on it tells me there is no fuel the low fuel light comes on. It was just a few months ago I changed the sensor out in the tank. The volt gauge tends to start fine but later on drop to 8V even though my battery voltage is 14.2 to 14.5 volts still. Now I plan on verifying the fuel sender to see if I can measure any ohm resistance at the PCM if so them the sensor is fine by the PCM had failed. Volt gauge I really can't test no way being the voltage is sensed and the reported to the cluster over the CCD network. I might be calling @Auto Computer Specialist and talking to them on warranty call.

I hope you guys will be able to help me out because I'm at a complete loss. So i have 2002 dodge 2500 with 174k and it has a rough idle when the motor is at operating temp. The truck idles just fine when it is cold, only when it is hot does it start idling like s**t. It almost sounds like it is missing, but I don't think it has a miss, I don't know what else there is to replace on this thing, everything is all new. This is a daily driven truck, it does not have a programmer on it, just 100HP injectors, 60/67/12 FPI turbo, 4in exhaust, BHAF, gauges. Here is a list of everything that have been done to the truck in the last 3k miles and it has not solved the problem. …

Hello guys, I recently purchased a 2001 Dodge 3500 5.9 5spd to pull my equipment. My equipment weighs roughly 15k plus my 25ft dual tandem axle trailer. The guy that had the truck installed a 62mm turbo, 125hp injectors and adrenaline tuner. On level 3, the truck black smokes so bad that I can’t even see my equipment and don’t really build much boost until about 2k rpm. Took it to my mechanic and ended up having a cracked head. Ended up getting a new head, changed the tuner to a edge and still have the same issue with to much smoke and not enough power. Mechanic is suggesting to go with a smaller injector size. Any suggestions? Thanks

Ok, so. I have read about the P0341 and possible solutions. Now the back story is that this truck had several faults and I was able to remedy 90% of them. It had P01689 & P01688..P01689 I believe is due to 56mVAC coming from my alternator. When I disconnected the alt. charge cable the fault went away. The P01688...had to replace the VP44. It also had P0222, which still comes up randomly, adjusted the voltage to .465VDC and APPS relearn and it is doing better. I keep getting P0341, it stumbles and idles rough then, it clears up and when it does clear up my tach quits working. So, I checked the wiring on both the cam an…

So, I decided to start a new thread on this. My truck has been running like crap since I installed my 100hp ddp injectors. I know they set the pop pressure at 290, which is low. But when it's idling, or driving under light throttle it almost sounds Iike it has a fuel knock. Not sure what is going on, but is there any reason why I can't pull them and set pop pressure to 320? Not sure if this will help or not. They are really smoky, which is the nature of them I guess, but it leaves a slight clearly visible haze even driving under lite throttle, so not sure if there are other underlying issues. Truck does have a airdog 100 and a new vp.

Well the Ram just ate another ECM. Must be high in protein. The first ECM went with around 3500 miles from new in 2000 when I bought it. The dealer replaced it & never said what happened. The second ECM went wild & through just about every code you could list. I think this was in 2008. Not repairable at the time. The 3rd ECM got replaced with a used one from a 98.5. I got the used ECM & PCM together from a guy in Montana. They would not work in my truck together, So I tried just his ECM & my PCM & the marriage was formed. That work fine up to about 2 years ago. Then the WTS light, fuel pump & grids started doing their thing. Then re…

02 ram 3500 5.9 Cummins. When I remove the fuel cap the tank releases pressure, is this normal? I looked for a breather for the tank but didn't find one. What I did find on the fuel module was a suction, return and capped 5/16 port. I removed the cap and attached a hose to it then blew into the tank. I could hear bubbling so I figure this is a auxiliary suction port? Dose this tank have a vent? If so where is it located. The reason for these questions is I feel it has a starting issue. In the morning, cold start, WTS, crank crank crank, short start and dies. Ignition off, back on, WTS, crank crank crank, starts and runs fine. This is 90% of the time. When warm crank crank…

The truck is a 1999 5.9 Cummins, for the past 6 months I've had intermittent problems which ultimately led to a no start, use to buck horribly until I turned it off and back on again, and it would run fine for sometime then back to bucking. Injectors are new, injection pump is new, so is lift pump. I recently took my ecm to get tested but they said they couldn't test it cause I tried to break into it (rookie mistake, I should've left it for the pros) which led me to buying a used one that came off a 2001 cummins, and still a no start, any help would be greatly appreciated, thank you

Well after 429k miles my cam sensor gave up. That being said let me show you my 104 mile trip to Council ID for a cam sensor... I get home to change the sensor but stuffing you hand below the VP44 in 32°F weather you start to have problems. I got smart and rolled the truck in the shop and plugged in the block heater. About this time @JAG1 calls... wasted a good hour or so on the phone BSing with him. After that I ran down to the shop and proceeded to change the sensor. Now knowing what I did for my buddy Russ his was an Allen bolt. Mine happens to be an 8mm socket. Grabbed an 8mm 1/4 socket and an 1/4 inch extension that is a wobble tip. Reached i…

Help!!!! Traveling cross country with truck and car on trailer. Trying to limp home 1500 miles with a badly leaking tappet cover (1 gallon oil leaks out per 200 miles!) Pulled in to get fuel. Went to start truck, heard click then nothing! All lights, dash lights, windows, cabin lights, etc. DEAD! Checked batteries, terminal connections, grounds, fuses, etc. all seemed good. Removed terminals from batteries and reinstalled them. Heard door open alarm so turned key to run. and had dash lights, windows etc. Tried to start, heard click again then nothing. Lost all dash and interior lights, windows, etc. again. Waited a few minutes and dash, interior lights reappeare…

Yesterday I had a client call me and told me he was coming. Ok he drops his rig off here and I had to run back to town any ways so I dropped him back off and chased the two Fords in Riggins. Get down with my jobs and head into town to just double check before I head home and the CEL comes on. I got two codes off the odometer but my OBDII tool showed nothing, no readable errors even though the CEL is ON. P12xx code and P13xx code. Never bother to write them down. After just hooking up and hitting erase they are gone and never came back. I figured if they are true code they would return. Nope gone and never came back all day. Even my trip to McCall no issues. …

My fuel pressure has been acting crazy. Started gradually increasing from 16 lbs to 27 lbs. I thought at first that it was due to cold fuel. I live at 9500 ft. Had this system for about 35,000 miles or so. 2001 2nd generation with DDRP Fass 95 mounted near the fuel tank. It did the same thing a while back and I got the pressure adjusted back to where I wanted it. Now I have to try it again. Is it the ball and spring in the Fass pump you think?

Yesterday I noticed a few drops of something on the pavement under the engine towards the rear. After driving home I also noticed a fuel smell once I shut the truck down and got out. This morning I went out with a flashlight to inspect and didn't really see any wet spots other than on the rear of the cylinder head on the passenger side. It's a little damp there. I'm thinking maybe the banjo bolt for the return line? Looks like it might be difficult to get to, anyone know the size off hand? Do I need to remove it and replace the sealing washers or do these commonly vibrate loose from time to time? Also, while inspecting I saw the the center section of the fron…

What's everyone one using for a map sensor? My stock one maxes out at 40psi. I'm suspect that I'm making more boost than 40. I have the quadzilla BT gauges and dont want to run manual gauge.

Just curious as how you all use your block heater. I am of the mind set that the more you use something the faster it will wear out so I try not to over use things if not needed. So that leads to: Is it better to leave it plugged in all night or possibly for a day or two at a time or would it be best to just plug in an hour or so before you fire it up? Any advantage to either practice? This morning the outside temp is 9° so I figured on plugging in an hour before start up today just to aid in warm up and easy cranking. It should start fine without it but I know it will be easier on the engine with a little heat in there.

I had my truck parked recently and someone jammed a rag up my blow by tube. I didn’t notice, when I got home the truck was leaking oil pretty hard and I crawled under and noticed the rag. Wondering which seal you guys figure the pressure would’ve pushed. Haven’t had time to check but looks like it’s coming from the drivers side of the engine.

Its supposed to get down to 0 here in Tx. Will two stroke keep it from gelling?

What’s going on guys? So as per my last topic the vp44 was my issue for whatever reason my edge wasn’t allowing my ecu to throw any dtc after figuring that out I found the p1628 or whatever the vp death code is can’t remember off the top of my head. Alright, replaced the pump with a reman vp44 from xdp and new fuel filters. Got the truck primed and she took off. Ran for about a day or so and then boom no fuel to the injectors again. Even though I do not like doing it I tried anyways I gave it a breath of ether and cracked the injector lines and still no fuel. Okay fine play hard. Towed the truck home and figured I’d call xdp and ask for my warranty (mind you this pump is…

In my down time lately I've been reading alot about injectors for the VP44 24 valve. Trying to learn and read reviews check prices and the like. I have looked through DAP and some others. Some look kind of "shady" or maybe that isn't the term but for whatever reason I didn't trust what they were saying. One on the other hand one seems to make some sense, Dynamite Diesel. All I know about this company is what I saw and read on their site and reviews of their products. I was just wondering if anyone has used their injectors? I did notice however that their prices are nearly double compared to DAP so I'm also curious as to whether or not it's worth it. .I'm not t…
