2nd Generation Dodge 24 Valve Powertrain

So here’s the project: 1998.5 24v: ECM, PCM, engine harness, pcm harness, engine bay harness, and gauge cluster all 1998.5 from same truck. The cab/ dash harness is a 2001 gasser. My gauges power up fine, shows rpms but nothing else. Gauges appear to pass self test. Codes 920, 921. DOES NOT give me a NO BUS... I installed my brothers 1999 pcm and no change, took my gauges and pcm to his truck: my pcm works and his gauges work in his truck, my pcm and my gauges work in his truck. His pcm and my gauges work in his truck.... So: I feel that the 2001 dash harness has different wiring than the 1998.5.... also my head lights don’t work properly. …

I have a 1999 dodge 2500 w the 24 valve cummins. The truck got vandalized and the meth heads cut the wiring harness in atempt to get the copper. The guy spliced it back together.

Till bat juice is gone…

So I have a 1999 24 valve all stock no tuner.. and I can start the truck and it fired right up and it will idle around 800 or so rpm and when I hit the throttle it will idle at 1100 and at highway speeds the truck will buck and if I let off it’s fine until I get on the throttle again I just replaced tps/apps and set the correct voltage and done the pedal thing the map and iat sensor are showing they work on my scan tool but no codes I’ve only owned the truck for a couple weeks and the vp44 has a sticker on it and it looks brand new all my ground are good but idk what to do.....

I have just build a 2006 Ford E 350 van with a 24 valve cummins / Allison trans and a 4x4 conversion. I got the engine from an auctioned truck (2001) on the title. Have it running and driving but in limp mode so far. Cam sensor code, After alot of messing around I called cummins and they told me the engine number and ecm p/n are for 1999 but my harness wiring colors tell me it is off the 2001. I have both diagrams printed out and seen the number 9 pin was empty and should be for the cam signal on a 99 so I got a pin from cummins installed it tagged into the grounds and 5 v with a new pig tail and hooked cam and crank up as I think it is meant to be but still throw cam co…

Hello, I have a 1999 24v what developed several problems. 1. batteries get drained overnight 2. takes it several minutes to get it to charge 14 volts. 3. lift pump will not come on with key switch 4. lift pump will not come on with bump of starter.

Still takes several minutes for charging to get to 14 volts. lift pump is not making enough pressure when running. Batteries are less than 1 yr old and they are interstates. lift pump is a fass that replaces the factory lift pump. its 2 yrs old. I …

First time posting on this site, i have to say this site is amazing always have found stuff that has helped me. Well im hoping someone could explain whats houng on with my truck. First and foremost the truck is a 1999 2wd 5 speed 3500 2nd gen cummins and it has a cold air intake and a intake horn, edge ez, 50hp injectors, new H. O vp44. The truck has 307k miles and runs amazing and has no issues. But when im driving on the highway at a steady speed around 80mph the sound in the engine bay will change every 15-20 seconds it is most deffinetly the sound of combustion changing and or the injection timing changing. The truck will have the typical knocky 24v clatter that sound…

Good evening, I have a 1999 Dodge 24v and am looking at replacing the fuel return system. Has anyone made their own return system? If so, do you have a list of parts used? I may just buy stock parts, but would like other opinions. I am looking at replacing the line at the back of the head, line from vp and the t fitting. The return line going to the tank is in good condition and does not need replacing. The other lines are rusting and starting to leak. Thanks, Tim

My truck all of the sudden stalls when I put into a drive gear F or R .when I do get it going it seems to drive fine until I get to a red light as I slow down at about 8mph it seems to downshift and idle goes up. when I come to a complete stop it seems as if someone is behind me pushing me and if i let off of the brake truck wants to take off. I made it home and did some checking and if i start it it idles fine when i get it to run in gear with my foot on the brake the accelerater does not respond .i can mash it all the way to the floor and nothing happens if i let go of the brake it will start to roll then the pedal responds.can anyonr help?Thanks

Hi, My 2500 has started hesitating when pulling a load or a hill when I ask for more power. If I back off it quits. It did it really badly yesterday morning when I was pulling a trailer but on the way home it was great until I started up a very steep hill. Today it was fine until again I started up the steep hill. I live at the top of a mtn and the road is very steep and about 1.7 miles long. I did put some fuel treatment in it and the fuel filter was changed about 10k ago. Any suggestions? TIA!

I have a 1999 2500 with manual trans and I added a Quadzilla XZT with a tune that has a high idle on it .I was coming home from work one afternoon and turned off the highway onto a residential street and my rear tires hit a icy patch and started to spin , the rpm's came up and it felt like the high idle kicked in and the truck tried to take off on me , so I pushed in the clutch to stop it and the truck just shut down. I coasted it onto another street and stopped and tried to restart and it wouldn't so I let it set for a few minutes and then it fired right back up . Is there a rev limiter that can shut the truck down or a relay that can trip causing it to not restart and s…

Sorry if this is brought up a lot. I did some searching but came up with nothing. I just bought a 1999 2500 24valve cummins, 266,500 miles, Ext cab, long bed, 4x4, Auto. It was all stock except the owner before me put a Airdog 150 pump on it. Since I bought it, I have put 4" straight pipe, BHAF, and have done all fluid and filter changes.(engine oil, engine oil filter, tranny fluid/filter, fuel filter, water separator,) I got through 3/4 tank of diesel and hand calculated my mileage, and it only came out to 13.1 mpg. This is probably 60% highway and 40% in town driving. I have tried my hardest to take is easy on the throttle, but every now and then the pedal dose get away…

Hey guys, so ive done several good wiring go overs and I can't get my truck to start. I suspect now it could be the neutral safety switch, but I'm not sure at this point since the reverse lights come on when the truck is in reverse. I'm out of ideas here. EDIT: I pulled codes with the scan gauge and got po602, and po1689 Also can anyone tell me what this plug is for? I believe there is a purple and white wire on it. I think it's the CCD, but I don't remember now.

Can I use the moparmans high idle switch with the quadzilla xzt? I want the 3 cylinder high idle for my truck.

Truck currently does not start I can disconnect one data link wire from vp and it will fire up and run. Currently it has dtc P0523 oil pressure sensor voltage high code.

Hi Guys. I have a ton of mechanical experience but very weak in electrical. I hate it. Bought a 1999 Cummins for my daughter that will be turning 16 in Sept ( she will be paying me back for the truck, lol ) and even with new batteries, if it sits for a week or more, the batteries drain to the point it will not start. I have tried to research this problem & have eliminated the seat belt modules are not the problem. What else could it be ? Any help would be much appreciated. On a side not, it also does what I think is a weird thing. Sometimes when you turn the key to the on position, the wait to start light doesn't come on & no matter how long…

Hey guys, I always start hear first when I'm researching something on my 99 Cummins. This is my first post, forgive me if I am not posting in right area. My problem is my batteries die after about 3 days of sitting. Notice my seatbelt light is now on, my radio wont go off with the key, my alarm will not peep when I hit the lock button on the key chain and sometime my wipers and windows stay on when key is off? Please help thanks in advance Ryan

Recently my truck has began having an issue where it takes a few seconds of cranking before starting where as before it would start as soon as you hit the key. I do have to wait the wait to start light comes on primes the pump and then goes off before cranking. If i don’t wait for the light come on and go off it will never start. When the truck has been sitting it always starts right up, but for example if I’m running errands in town and shutting it off and restarting that’s when it takes longer to start. At times it’s not started at all, so I let off the key and the pump comes on for 20 seconds or so and it starts right up as long as I crank when the pump is running. …

Goes in high just fine. Use it in and out in alaska a bunch. Hardly ever use 4 low now for several years . I know to back up neutral etc it just will not go in and and sometimes makes a just awful noise So what is the problem??

Ok looking for some advice. Ok, so I bought a 99 dodge several months ago. The engine has been swapped out for an 02 engine and computer. The internal tone wheel had been retrofitted to the front of the balancer. For several months the truck had a p1690 code. I did all the checks on this page and everything checked out fine. I finally got it to go away by rotating the tone wheel 180 degrees on the balancer and the code is no more. Worked good for about an hour, than I got a code for p0216 accompanied by the dead pedal. Truck has always had a lopey inconsistent miss at idle. Even after the p1690 code was fixed. I can Ho…

My 1999 dodge diesel has been running fine except for rpms going up and down at 45 mph. Below that its fine and above that its fine. Thats just background info though. The truck just died. It cranks but wont start. I replaced the lift pump a while back as well as the throttle position sensor. Truck ran for a few months after that. I dont have a code reader and toggling the key does not generate any codes. Not sure where to turn to next. Any ideas? BTW the truck has 175k miles on it.
