2nd Generation Dodge 24 Valve Powertrain

99 Dodge 2500 24v p pump man trans. WT- ground wire mod has been done. Fass pump. It started periodically no gauges then a mile or two down the road all gauges would start working ? Was always in a hurry. Never messed with it. Have a Edge II and it would lose connection, touch the screen would it come back on screen. Never showed NO BUS on dash, when this took place. This has probably been going on close to two years. I never was able to look at it. I got Covid 4 times and was very sick. Better now. Gauge issue has gotten much worse as of last month. I would cycle the ignition and the gauges would stumble and eventually come back. If the truck sat for 2-3 days batteries…

Hey again guys. Picked up a '99 2500 today with a few issues, chief amongst which is the converter not locking up. Overdrive works just fine. I began troubleshooting today, but I could use some input. It had a bunch of codes before I began measuring, most seemed to be related to the previous owners lockup switch because once I removed the jump between the relay 30 and 87a pins, and installed a relay in its place the codes could be reset and wouldn't come back. Now, according to the previous owner the lockup suddenly stopped working, not gradually. Solenoid assembly is new, and I've checked the contact at the transmission, it looks good and clean. When I measur…

I have a puzzle to try and figure out. A friend brought his truck to me because it was bucking and surging. I drove it, it was. I checked fuel pressure and found zero fuel pressure from the lift pump. Truck was running without lift pump fuel pressure. He said to me he had just replaced that intank pump about a year ago. This truck had the original lift pump on the side of the engine replace ten or twelve years ago so this is the second intank pump. What I found was when I bypassed the relay the pump would run, put out about 14.5 PSI. I found that the in line fuse that is in the power feed line to the relay was disintegrated. The only thing left were the prongs of…

I just made a run from northern CA to southern Oregon. All was good on the way up but on the way back I noticed some surging, especially when at light throttle on flat road or off the throttle going down hill (coasting but still running 2000 rpm) . I switched tunes from my MoparMan mileage tune to the tow tune and no difference. I also hit the overdrive button and no difference. Fuel pressure was always 15lbs or more. By the time I got home I had a check engine light and it was 0236, Map sensor. I have cleared the codes numerous times and I might get away with driving a hundred miles or so with no code but the surging continues. A day or so later, the code comes back. …

So it never caught my eye before but Its bent. Either someone before me backed into something or jacked it up by the sway bar. Its got to be replaced so go back with stock or is there something better?

I have used a 150-amp fuse on the last three W-T mods I have done and want to try a circuit breaker on the next one. So my question is which 150 amp circuit breaker did you use that is trouble free and where did you get it.

Hello all first time poster here. I have a 2002 2500 cummins that will crank but no start. I thought I had a bad ecm so I sent the ecm off to be rebuilt along with the pcm due to the age and mileage on the truck. I have received my computers back and hooked everything back up and to my frustration I still have the same issue. I checked the black and brown wire on the ecm I believe pin #30 and came back with 9.99 to 9.97 ohms according to my reading anything less than 10 ohms means it’s a bad ecm. Are these numbers so close that one shouldn’t condemn the ecm as bad again or no that’s a issue right there? Any help or advice would be greatly appreciated I will also be contac…

hi i have a 2000 dodge ram 3500 24v cummins. just recently all the dash lights and gauges power up on there own, like the ignition was turned on but the key was in the off position. i could tilt the steering wheel back and fourth this would make the powed turn off. i started the engine and it would not turn off until i tilted the steering wheel. the truck has higher miles so i replaced the ignition switch hoping that was the issue, but the issue came back tonight. also when you shut the passenger side door kinda hard it would make the dash and gauges power on. i figured i would run it by you and see what you thought. thanks in advance

I have a 1999 dodge ram 2500 5 sp manual. We have a perplexing problem. I`ve had over the last year a code of 1698 and Crank position sensor code PO336 thrown. The truck started having a hiccup when idling and the tach would drop off and come back and check engine light coming on. Eventually the truck wouldn`t start at all. My electrical mechanic replaced several relevant pins on the plug to the ECM then replaced the connector on the VP44. Previous to that we put a rebuilt ECM on. What he thinks is there`s a timing issue with the crank position sensor and the VP44. The truck starts and runs but is throwing these codes most of the time now. I`ve heard tone ring?, Key on t…

Well I figured on retiring my old grand Cherokee because it burns so much oil and the rear bushings are shot. So that left my truck or my 1971 lincoln to drive, since the car is mint, that leaves the truck. Still don't have the ECM done but I can do all the gauges myself with my CCD bus done. Truck runs good even with stock injectors my transmission is going to hate me. I blew the exhaust apart and muffler is trashed from dragging. I replaced the AC compressor, lines, accumulator, flush vac and fill works great now. I replaced the starter twice now. Sometimes things were screeching and squeaking, thought it was alternator s…

Well now that I have started driving the truck again with the VP44 project going and testing. The starter is doing the ole click-click thing sometimes Ugh. It's probably on a third set of contacts by now. The last set of contacts I ordered were the wrong ones. I was in a hurry so I took it to a shop to be fixed last time and put it back on the truck and the gear would sometimes touch the flywheel going up hill. So I had to take it apart and mess with the return spring. Anybody had this problem before? I'm thing about just buying a rebuilt one because the brushes are likely worn away after all the previous fixes.

So back in April DAP sends an email launching the new Quadzilla injectors, but they don’t sell them on the DAP website. What’s the difference in the Quadzilla injectors vs the new DAP injectors they sell on the site? (Besides the green rubber seal)

I want to thank Mopar Man and all of the members that have shared their knowledge, experiences, and wisdom in our endeavor to maintain and perfect our Ram Cummins. You guys have a real passion for these machines and your willingness to share and help strangers is a fine example of the type of individuals you are! Cheers to all of you! I have been learning from this site for several years, first as a non member and now as a subscriber. If I look hard enough I will find the information I need to solve all the different issues I have taken on with my Ram. The expertise and technical insight I have gained from all of you is beyond any expectations I ever had. …

So Mike let me come hes selective about that ;) Lots been going on. Picked up a f150 to drive while my truck was down but ended up giving it to my daughter. So i was out a daily driver stuck driving our work truck a 04 cummins. My tourque convertor went out with 170k on it. So i bought one local after seeing the guts they put inside The convertor in my truck was supposed to be low stall it was stock, didnt have a one peice fiber, it wasnt brazzedd for support basically the cheapest thing you could get So i got a lower stall billet piston brased, one peice fiber, reamed for more volume. …

I'm working on the truck in my sig. After installing all my upgrades last fall (pac brake, hx 35/40, 100 hp injectors, quad unit), I haven't been able to get over about 25lbs of boost even with the set screw in the boost elbow turned all the way in. Today I put a vice grip on the hose and saw a bit over 30ps of boost on a full throttle acceleration. Where in the adj process do I check the actual wastegate actuator setting/position? Its possible correct, to maybe need to adjust the length of the actuator rod? Also, I bought the manual boost controller shown by Mike in another post and have yet to install it. Mike, the red end goes towards the elbow correct?

Alright, I am trying to work through an idea of mine in regards to lockup. What I am trying to do is figure out how to predict the 1-2 shift and predict the 2-3 shift. So the question I have is what happens to make the VB decide, Time to shift into 2nd. and what happens in the vb to shift from 2-3. Is it a pressure difference between the tv and vb pressure? I don't really understand what happens in the rats nest of a VB. So is there something I can watch VIA a pressure switch or whatever to show that the trans is going to shift? Can someone smarter than me explain the magic of how a 47re shifts in low gears? Reason I am t…

I can not find the parts list PDF file. I thought I had downloaded it. Does anyone have this file please? Thank you!

I might have made a mistake in my build purchase. First and foremost, I've got to deal with CA smog checks. It was mentioned to me that techs were now looking for Holset being listed on turbos. I know this is dependent on individual techs and most would not even bother. I'm pretty sure the place I go, this wouldn't be an issue. But you never can tell when this would change. I really gave a hard look at this "Super 9" a local company builds . I'm second guessing my decision not to go with this. I don't really care about HP numbers. I care about towing a 10k lb travel trailer through mountain passes. I have a mildly built auto, 3.55's running 265/70/17 Michelin's. I'll like…

I had a bad MAP maybe 2 or 3 months ago so ordered a SMP MAP from Rock along side the long steering joint, long story short, the steering joint bashed a hole in the box and on arrival no MAP, it had simply fallen out somewhere in the well over 3kmiles to get to me, to be fair Rock sent a replacement straight away, actually within the very same day as the delivery day, cured the no boost problem no bother Fast forward 2 or 3 months and the same deal, intermittant no boost then everything all good for a indetermined time then no boost and NO power I have been running my quad on LVL1 stock with boost fooling due to the damn cost of fuel here in the uk, order…

I have a 2000 Ram 3500 Cab & Chassis NV4500. When I got the truck, it had a P-pump converted big turbo 24v built for pulling in it, but I bought the truck and not the engine. I pulled that engine and bought a wrecked 1999 dodge 2500 that ran fine but they needed the VP44 off the engine. So I did the engine swap on this truck, pulled the p-pump motor out and put the stock 2000 engine in it. I used the ECM from the 5 speed truck I currently have and a new VP44. I put a new MAP sensor, APPS, and IAT on the engine while it was out to make things easier. The problem that I have, is that the engine goes into a "limp mode" or defuels. I know the 2000 doesn't have a limp mode…
