2nd Generation Dodge 24 Valve Powertrain

I am going to at least begin this mod today. I just received my 150amp breaker yesterday from Amazon, I'll still need to pick up an online fuse holder for the pcm as well. I do have a couple of quick questions. 1. What size fuse for the PCM? I read both 7.5amp and 5amp. 2. I read that the ac noise would affect cruise control somehow on a manual truck. I haven't used my cruise much, just wondering how it affects this? Any other things it could mess with? I will take ac noise readings before and after to see how this works out and report back when finished.

Hello So I've been searching and can't really find a ballpark so I figured I'd ask 01 bummins. Trying to pass emmisions on it currently. Tripped the speed sensor and grid heater code came on (deleted from previous owner) replaced the speed sensor and drove it 130 miles to clear them. Speedo came back so I know speed sensors good. No change in CCM. Anyone have an idea how long this may take to complete the drive cycles if everything is good? I checked my scanner a few months back with it for another speed sensor code (Snow Donuts) and it said all my monitors were ready so I know it has the will to want to go green. Edit: when I was drivi…

I have a 2001 24v and it will read 40 psi of oil pressure weather its running or the key is just turned to the start position. I might add that it still reads 40psi with oil pressure sensor unplugged well. I have tried a good know cluster and it does the same thing. I've cleaned all grounds and checked them. Anyone know what it could be?

My 01 Dodge 6speed is stuttering between 1350-1600 RPMs periodically. Its occurs under acceleration, typically at about 1450 RPM give or take 75 RPM. Never seen it happen above about 1600RPM. Its like a loss of power for about the count of .5 of one. Enough to know it occurred and then its back to normal. It seems to happen in the first 30 minutes of run time while the truck is still cold or cool. Fuel filters are new in the past 6 months (probably less then 10k miles) and its been occurring through at-least five tanks of fuel. I have re loaded my Quad Adrenaline tune and that does not seem to have an affect, i have …

I was curious on the opinions here on the use of seafoam to flush the oil system before an oil change. I have used the product before on gas engines with decent results. With a diesel engine being a more "dirty" engine and reading about possible valve and lifter bores becoming varnished with burnt oil on top of not knowing the exact history of my engine I was considering dumping a can in the motor oil and letting it do its thing to clean the oil system. Any thoughts? Thanks.

So I have finally got my truck up and running after an extensive amount of maintenance that needed to be completed as the previous owner neglected the heck out of this poor girl. While everything was being worked on I went ahead and did the full W-T wiring modification and the alternator PCM protection as well that @Mopar1973Man has been so awesome at spreading around to everyone. I did not check the AC volts prior to the maintenance and W-T mod. I went ahead and took a video of my results while the truck was running, unless i'm doing something wrong or have the incorrect setting my alternator is beyond BAD reading in at 1.04 AC volts which hopefully is the sm…

So I finished the W-T ground mod and was finally able to rule out the injection pump as my no start problem. Sort of. I followed the diagnostic from Bluechip Diesel and others to do some basic electrical testing at the VP harness. I verified that pin 6 was grounding, and pin 7 had power at the RUN position on the ignition but NOT on the START position. I didn’t check the power situation on the wire to pin 5 after reconnecting the plug because I didn’t have power on 7 at the start position. I also ran test leads to pin 6 from battery ground and pin 7 (fused) to battery positive. Truck fired right up. I couldn’t find anywhere on a forum so far where someone explains what m…

Guys i am in need of some insight. I have a 1999 24v cummins. This truck has been a headache to say the least but i am at a standing point. This is what has been replaced in the last 6 months and has been at 4 different shops including a chysler dealer. They have all given up but i am not ready too. The truck will only run when the c3 plug on the PCM is unplugged. This is the plug nearest the passenger side fender. This is what has been replaced IP Liftpump- stock replacement PCM- has been flashed to match VIN at chyrsler dealer engine harness has been replaced with one out of a running truck with same year and details( 4x4, auto )…

Thanks in advance for any advice! Went to start my truck today and ran for about 10sec and died, can't get it to restart! Fuel pump seems to be working, have fuel coming from lines at injection pump, inlet and return, no codes I'm aware of, I don't have a reader just with key procedure. What's involved with checking injection pump? (Please don't let it be that!!) I'm a diesel noob and fairly new to me truck, please be gentle ? Thanks! Don

New here, but not new to dodges. Some of you will probably know me from CF. My grandpas truck, 2001 Cummins 47RE and completely stock, spent all day working on it, various things, but I did some diagnostics and thats why I am here. Ill start with the gear hunting issue first. I tested AC noise. has about 0.03V, which is 'acceptable' apparently. Okay. Had no real way to log the truck while driving, I dont have a snap on scanner or similar to watch APPS and other parameters that might effect TCC operation. This diagnosis was kind of a dead end. Mostly I wanted to identify AC noise and go from there, which I did. Issue seems to become m…

Alright so I've got this 24v project im working on - don't have any exp on them and I heard this is the spot to go... Trucks got p1689 flashing, p0113 codes. Previous owner said it "wouldnt go above 20km/h". I havent tested that theory because I suspected the lift pump. I have a FASS100gph & set of glowshift gauges going in this thing shortly but I wanted to confirm the source of these codes before i mess with them. I also am having, what I believe to be the sending unit act up on me. Fuel gauge at E, but when I disconnect / reconnect connection at top of sending unit it jumps up to half then slowly climbs down. Tested the gauges on the dash, and fuel gaug…

Good morning, currently installing my FASS 165 LP and the directions have me installing an Add-A-Fuse into a ignition hot fuse under the hood it does not talk about wiring the LP into the PCM at all. Can someone point me in the right direction as to where I should place this "add-a-fuse" for the ignition hot. I've added the install manual i'm working with for reference, it's on PDF page 13 step E and F. Thanks and cheers! TS-D08-095G-or-TS-D08-165G-2.pdf

My son has a 2002 Dodge 2500 Diesel has codes P0522 and P0336. The oil pressure switch, which is a single wire switch, has been replaced with a Cummins part and the PO336 code is troubling because there is no crank shaft sensor on a 2002. When you start the truck the instrument cluster shows no oil pressure and the tach is erratic for 8 seconds then drops off and the truck runs at a normal RPM but is in limp mode. ANY help would be appreciated.

I have a code just set for the first time yesterday sure yesterday it was PO238 map sensor voltage high, I cleared this yesterday to see what would happen today Turned ignition on today and PO237 map sensor voltage low set, no PO238 Done the diagnostics for the 237 code and everything checks out except map voltage is 0.5v ignition on not running or running, it does increase to around 1v to 1.6v if stalled in gear I got 5.2v on orange which tells me the 5v supply is good, no other sensor codes set no short to earth on the other 2 wires or each other I haven't disconnected the ecm plugs and checked continuity of these two Fitted a quad a…

My trans stuck in 2nd after rebuild changed gov an tranducer. And has no codes was thinkin maybe kickdown cable Should i adjust slack screw should that lever be touching valva body pin

Ok guys got my vacuum pump resealed, no more oil being pushed out the CCV, and got my vacuum lines replace so my heater works on all positions. Fixed the banjo bolt leak on the back of the head, and T fitting leak on the return line. But I still have a bad problem until the truck is fully warm it has no power still, and if the outside temp is below 40 it loses power bad. And still have a hard starting issue has to crank for around 20 seconds and then until it sets for about 3 hours itll stat back instantly. New batteries, cranks fast, new fuel filters, fass DRRP lift pump. 15psi fuel pressure idle, 9 WOT. Any ideas would help I'm thinking my VP44 is shitting the bed it's …

Ok. So long story short, I tried to swap the old 150 injectors into my truck after I went through and set all the pop off pressures with shims(diesel class project). They're pretty much junk, considering they do nothing but just smoke out everything behind the truck. I ended up going back to the stocker set I got from a good guy from here (name escapes me atm, but thank you again amigo). Had hell getting the truck started again, which I think was because I backed the truck into my spot at home, and it was leaning back slightly (the road has a crown). I got a friend and he helped me get her going again, but as it was idling, it started pouring fuel out of the bottow. We tr…

Came home from work today to find my new Dynamic valve body sitting on the table. Forgot to pick up a new filter so I'll have to wait until tomorrow to put it in.

Damn was getting ready to do the WT ground mod and noticed the upper mount tab is broken on my Alternator. It's a bosch. Are the bosch and denso alternators interchangeable? I've been shopping around for a replacement but seems to be some confusion about the correct alternator, depending on the eighth digit of the vin. ( in my case it's "C") Advance auto has the actual bosch alternator (based on the alternator part#) but the listing says it's for trucks with a vin: 7 https://shop.advanceautoparts.com/p/bosch-premium-100-remanufactured-alternator-al6400x/20851271-P?navigationPath=L1*14920|L2*14999|L3*15587 Rock auto has an alternator …

Hi Guys.. new here, but have been reading as a guest for a while. I’m always amazed at how knowledgable a lot of you guys are and all the helpful information available. Here’s my situation, and I’ll try to remember a much detail as I can and in the proper sequence. Last year my truck was sitting for about 7-8 months without use. I was helping one of my parents out of town and wasn’t able to do much else. So when I got home, my truck batteries were totally dead. These were new batteries, maybe 4 months old prior to leaving. I couldn’t get them to take a charge. Took them in, load tested, replaced. Then the truck’s EVS II system wouldn’t disarm and I think the d…
