2nd Generation Dodge 24 Valve Powertrain

Hello all, I am new to this site and wanted to kick something around maybe get some feedback and troubleshooting help. When i would turn on the truck, i would usually let it idle for awhile. I would put it in “D”, push on the gas, the truck would start to travel, than it will suddenly get the case of the "dead pedal" and then kick into gear. This started in a sporadic fashion. It then led to a daily ritual to get to work having to rev-up the engine in order for the truck to move. I have briefly explained below how I got to this point. The beginning of this story is as follows: I initially replaced the fuel lift pump when I first got the signs of white smoke c…

P1765 Transmission relay open or shorted. So I remember that the Previous owner told me about a Torque converter Lock-up switch. He said that you could use it to lock the converter in second gear while pulling a grade. So I assume that the Jumper wire has something to do with that? Mopar1973man told me about a Mystery switch that someone did, and used an old High Beam floor switch but I can't find that article. If I'm going to have to suffer the effects of the jumper then I should reap the benefits. If someone has a link to the rewire please share it with me. Thanks Michael

I am relatively new to the forum but have heard of Moparman and used his wiring maps for a while. They are very useful. Very good job. My throttle surging issues are caused by varying voltages to, and subsequently from, the APPS. I have the same issues with the alternator and/or PCM disconnected. The issues are as follows: -Truck starts right up but idles erratically -engine idles fine with ECM data lines disconnected from VP44 (wires removed from connector) -engine idles fine with APPS disconnected (no fluctuations in incoming voltages) -40 HZ (or thereabouts) "signal" in power and ground with and without alternator (oscilloscope screenshots ava…

This thread is where I will post updates of my modifications, issues i've had, and potential upgrades I'm considering. This page is dedicated to @TFaoro, because without him my truck would be bone stock still.... To start off, today my VP died. It took me by surprise, as it gave no indication there was an issue. But, it threw Death Code P1691, and that's that. Good thing it died before I bought tires. Is DAP everyone's first choice for a new VP?

So I've always had a little miss, I would noticed it with my edge jammers 150s with the comp on level 5 at WOT, not bad enough for me to worry about. But I upgraded to a quadzilla and also got 7x.013s , the miss turned into a very aggressive buck, it's literally breaking my dash. I notice that with the quad on level 0 it doesn't do it but with the quad on at any other level it does it, the more aggressive fueling the worse and it even does it on level 2 with less power than stock , as soon as I put it on level 0 I have no buck on my throttle. Any ideas would be appreciate it to help me tackle this some of the mods are SO pump, t3 66/74/…

2001.5 Dodge 2500. It's parked in stepdaughter's yard in Attleborough, Ma near Pawtucket, RI. I have a couple of days. It's leaking coolant at front of engine. It's pretty wet but the center of the wet is the water pump. I don't know who to take it to that I can trust. With my MS, I can not do my own work.

truck cranking no start, no bus,wait to start light stay on very dim. I have been chasing this no bus issue and as soon i unplug ecm everything comes back to normal no abs and gauges start back working, so i decided to take ecm off and was a ratling noise comming from the inside i oppened an one of those capacitor came unsoldier so i soldier back put ecm back and no work! still shows no bus wait to start light dim and no gauges working so I decided to send ecm to Auto Computer Specialist and they told me my ecm was fried no fixing so i need a new one they want 1599 since my ecm can not be repaired does not count as core. I found a cheaper one somewhere else…

Customer called me yesterday asked if I could tow their truck in and see if I could figure out what's wrong with it! It's a 99 2500 2wd auto with stock 24v new lift pump and reman vp44. The truck starts and lopes hard with no throttle pedal. No engine codes. Anyone have any ideas? The vp44 was put on about 4 months ago and it's been sitting at another diesel shop for 3.5 months. I don't know where to start!

I have a 2001 dodge cummins. When I turn the key to the on position I have no wait to start light and hear a click in my fuse box. I have went through and checked wires and fuses and have had no luck

OK I got time to do some digging to update I was driving down the road and it died would restart only idle rough no thottle response, but after starting four times doesn't idle anymore. Codes were 1688/1689OK 20 psi going into the pump, fuel spits out at injecter line( don't know how much) put a different injecter pump in that I had and it still is the same way it was after it died. Cleared codes and none have came back. Any ideals where to go next, thinking start at the batterys and check every connection I can, will have to take to a dealer next don't know where to go. Thanks for the help:banghead:

Was driving down the road and what I thought was an inch of water turned into a foot or more. Truck just shut off immediatelyand none of the gauges work and my edge doesn't communicate. how long till the stupid ecm dries out? At least I'm pretty sure that's what happened. 98 24 valve

Running fine, turn corner push to 1/4 throttle instantly dies coast to shoulder. Sits for about 10 min to give a once over. turn the key it rough idles for 2 min then smooths out. It continued to do this rough idle start & then smooth out. Towed it home. Changed fuel filter, hooked up my Smarty to read codes. (7) codes P0251 Fuel Inj pump fail (replaced lift pump 6 months ago carter) (I can hear it run when bumped) P0252 Inj pump fuel metering P1688 Internal fuel inj pump controller fail P0254 Fuel Inj pump mech fail fuel valve P1693 Generic fault indicating fault in bus or PCM/ECM interface P0602 Control module programming error P0…

Hello all, I too am in a similar situation with my truck.....I recently took ownership from my uncle, who recently passed away and left it to me. I would normally never own a diesel, but as I mentioned....it has much sentimental value to me, I have to do my very best to honor my uncle. That said, he had spent a large amount of money on the truck, he has all the bells and whistles you might expect, the Quadzilla system, the exhaust extras from Bulldog and on and on it went. I am not very skilled at mechanics, but I am a cheap man, so if I can do it myself, I will. Still, the problems seem to be adding up, and now the truck will not turn over at all, its obviousl…

Made a quick trip to the store and on the way back while slowing to make a right hander the Cummins Died . I coasted to the curb. Could'nt see anything wrong. drain a little fuel for Airdog 150 at water filter too see whats up there, looked ok. WALKED a block and a half to get tools, (I Know:lmao:). Remove Fuel PSI sender and add another gauge and was reading 17 before cranking, just the bump of the started so there is psi to injector pump. Then I called Tow Truck:banghead:. Too heavy for me to push that far. After I got home started reading about this, Ck code and found nothing. Now I ask should i ck the keyway at pump or what next? Any advise would be very helpful.--- U…

Several days ago, my truck died while cruising at 60mph. There was no warning, pops, knocks, or clunks. The rpms dropped to idle then a few seconds later dropped to zero. Truck had full power until it died. Fuel pressure is good. Only throwing the p1693 code.I believe it to be a ground issue. The truck radio lost memory after sitting overnight and turned the am radio on. I'm looking for wire diagrams or someone who has maybe had a similar issue or any ideas. Anything will help!

As I was driving home the other night I did a 5th gear heavy acceleration. Just as the truck really started getting goin, it shut off and is yet to start again. It will crank like normal but wont turn over. Cycling the key these codes were shown: 0122, 0500, 0460, 0222, 1693. I looked them up but need more opinions. Not listed in my sig is a fast 150 titanium. I'll fix that. Thanks in advance.

I was driving the truck and it just died. I checked the fuel pressure by bumping the starter and have about 12 psi. As soon as I turn the key the pressure goes down to 3 -5 psi and bounces. I have a raptor 100 pump on the truck. I jumped the relay for the pump and it constantly pumps at about 12 psi while trying to start the truck. I do not believe that the pump is bad due to it working just fine while jumping the relay. I cracked an injector line and no fuel comes out when trying to start while jumping the pump power. Any idea what would cause the no start and the raptor to act like that when starting it connected to the relay.

I’ve recently noticed that when my truck is at WOT the truck will shut down and I will have to crack a few injector lines and bleed air out of the lines. Has anybody else had this issue? It happened last night after I installed new 275hp injectors and did one hard pull and it shut dow, I pulled over and knew what todo from previous incidents. Is it possible I’m out running my VP44? Or the fass150 titanium can’t keep up?

So forgive me if this has already been discussed but I went back 20 pages and didn't see anything to help. 2001 HO 6-speed. FASS DRP, 75hp DAP injectors, Quad XZT+. New PCM a couple of months ago because I had been running an external voltage reg but hated the flickering lights and engine lope at idle. I replaced the vp44 with one from DAP 2yrs ago after intermittent stalling at highway speeds. Ran fine with 2-3 instances of a 1 sec miss at highway speeds last summer. thought this was possible injectors as it has 215K on originals so replaced them 7 months ago. this July when it hit 95+degrees I stepped on clutch to turn at an intersection and the truck died. …

Ok, so as my title states, my truck never came with a lift pump. I only have a FASS titanium fuel pump, and huge lines running straight to the vp44. Would it help anything by putting in a stock lift pump later? Or can I just keep my current setup? Lately it's been loping kind of funny now and then. I'm terrified my vp is getting ready to **** the bed. I'm heading to Williston ND tomorrow to start work Monday, but that's easily a 16hr drive for me, if not longer. After Gillette WY there's alot of empty roads and no service.... Im going to change the fuel filter and water separator just to be safe before I go. The truck has made it from Casper Wyoming to Dickinson Nd, …
