2nd Generation Dodge 24 Valve Powertrain

Last week is when this started. I was chasing that P1689 code and ended up replacing the data link connector on the edge harness and it seems okay so far. But looking at the map sensor connector this morning i noticed it was missing the rubber seal on both end of the connector and the pins looked to have some oxidation on them. I cleaned them and put some grease on there and no luck. Whats weird is no check engine light and everything seems to be running normally. If i didnt look at the gauge i would have had no idea it wasnt reading anything. Im hoping someone knows what that connector is called or who makes it so i can order one up and replace it…

Good morning everyone, Yesterday I started using 2 stroke oil at fill up. I have a reman vp44 from T-bred with 1000 miles and been reading 2 stroke oil is the way to go for pump longevity. After I filled up I noticed my FP was at 14.5ish lbs compared to the 15lbs it was at before adding the 2 stroke oil. Is this normal? Has anyone else seen this? I have an Airdog 4g lift pump so I'll just increase the pressure tomorrow but thought it was odd my fp would drop. Tim

Today I happen to notice this larger puddle of oil under the truck. Looking underneath it was coming from the PS pump and dripping at a rate of a drop every 30 seconds or so. But why...? The engine had been off for a day and no one was ever in the truck at any time doing anything like trying to turn the steering wheel or touching the brakes. Thinking a hose let go, I eventually came to the conclusion that for whatever reason the PS fluid level raised up high enough to spill out the top and make a mess...with the engine off no less. Yes, the fluid level was very high. Then an hour later when I was parking the 5th wheel back in its spot I felt this weird b…

A few months ago I replaced the in tank lift pump & kept the old one to take apart & mess around with. I really like the idea of the fuel pump in the tank, IMO that is where the pump should be. the Gasser cars get hundreds of thousands of miles on in tank pumps @ high pressure, It sure seems like someone should be able to make a diesel transfer pump that could do the same..... in any case, Ive often wondered what the yellow cross thing is in the module so I took it apart & figured you guys might want to see.. I figured someone might need to know which wires goto which pins on the inside connector. …

Hey guys going crazy here the last few weeks I have been having problems with my 99 I have codes p1693 , po602 po122, have a smarty and running stacked with a edge cts , have replaced the tps, crank sensor, and alternator all last week and still hasn't changed still pulling low voltage code to the tps could it be a bad ecm or pmc once i start it of a moringit wll rev up and down on its own in till I shut it off and clear codes then she runs fine , any input would be nice thanks in advance

I have a 24v 5.9 Cummins 1999 with the vp44 injection pump that doesn't have the power it once did. My fuel pressure is 12 at idle speed and 10 at WOT... The engine runs fine, starts very good, and no smoking of any color. It's very slow on take off, barely gets to 2,300 RPM only on a down hill it would reach as far as 2,8000... All my fuel fuel lines and fuel filters are NEW... PLEASE HELP I'M OUT OF TRICKS...???

Is there a way to test VP44 health when there is no codes? My truck ran like crap this morning. Very chattery and doggy. I’m wondering if my VP isn’t going south. It started pretty well but was pretty chattery for only 25 degrees. Scanned for codes and got nothing.

I know it's not cold enough yet but, to lessen my idle time by the house this winter (baby) so I plugged in heater to make sure it worked and everything was normal. I plugged in the cord for the first time in 2 yrs and the plug ark welded itself to the power cord, and where the plug goes into the heater element started to smoke an make gurgling noises. Is is there a way to test the cord or the element to figure which part is faulty? As far as I know the element and cord are factory.

I finally got my truck to start and drove it last night after a year of sitting since last August I've already replaced the vp44,intank pump, fuel filler, tps and tonight went to start it started fine had no throttle and fuel level gauge. I had only had one code and it was a 122 code. these are all the codes that randomly appeared. I'm extremely mad it was literally doing fine last night and over whellemed with all these if someone could please help me out it wound be appreciated P 0500 @pull fuse 4 and 7 P 0463 @ high voltage to fuel pump P 1693 @ Ecu 121 Excelerator position sensor APPs voltage to low 1693 P 0380 @ Intake air …

I know this should start a interesting debate but I’m curious everybody’s opinion.... I want to change the oil in my Cummins turbo, curious what brands you guys recommend, previous owner ran Rotella 15 W 40 and change the oil every 7 to 10,000 miles, he also ran a quart of Lucas at every oil change, my question is what are you guys thoughts about running a full synthetic and which brand?

I’m leaking fuel from a plastic line connected below and to the right of the fuel filter. I took out fuel filter but can only get one hand by the leak. I’ve tried getting at it from underneath and can’t. I took the wheel well plastic guard off and there is no room. My only option that I see is cutting the metal out of the wheel well big enough to get my hands at the problem. Would there be an access through the fire wall I don’t see. I think I put my fuel gauge in the wrong place because it aways maxes out at thirty and never goes lower. Besides the fuel leak I’m worried about my injector pump because my truck aways started right away and now I have to crank it multiple t…

I have an automatic trans so what is the best way to hold the engine from spinning while loosening bolts on the dampner? Changing this weekend since the rubber is supposed to be even, flush to the steel. Mine is mushed out all around and wobbles when running.

Hi everyone, I need some help, I have a 2001 dodge 24v and I bought the Denso diode pack from the site store to replace the diode in mine. I knew I had a Denso so I bought it. However, I didn't know there were different models. Can I just modify my alternator body to fit the new diode pack? All the holes line up except where the lead comes out of the alternator. Or is there something possibly different between the 2 diode packs? The only real difference is where the lead comes out. The original it comes out of the side. Where the new one comes out of the back. here you can see the new one on top with the lead pointing up and the bottom…

Denso Alternator Modification I'm doing this write-up in case anyone runs into the problem I did and they don't want to buy a new or find another style alternator. After I bought the diode replacement and tried to install it I realized that it was slightly different from mine. Note: The new lead is smaller in diameter and shorter than the old lead. Here is a link on how to take the alternator apart written by IBMobile. If yours is like mine and the lead comes off the side the B+ post nut sizes will be a 13mm but the steps will be the same. Tools required for modification: * Small cut off wheel or Air saw * Ball-peen h…

I have a 2001 2500 4x4auto. I recently changed the entire body which was rotted to gas truck body. Went fairly well until I started truck and found out that power steering pump shaft broke? And hydroboost went as well. Fixed both and can steer and stop but now tryed to drive it and when u shift out of park it basically jumps into R or D depends on what u select,seems like brakes almost don't want to hold truck back,try to accelerate and truck moves then slows down then shifts then revs then shifts and 40 is highest it will go will Erving high?please help truck drove beautifully before changing bodies. I'm new to site so please excuse the way I described this problem,thank…

I have a no start a lot of times if I jump in a turn the key on. If I wait for all the dings on the dash it starts every time. Is this normal? I has been like this for a long time.

Ok, so pretty confused right now and hoping for clarification. Btw it's a bit of a read... What happened, lost control of o/d switch/ could not disengage but trans acted normal, where I am at we have had some flooding so on my way to work in the dark I missed some high water around a bend and went through it at speed no deeper than the axles not even ten miles up the road o/d hunting began got to work a few miles down the road and called the builder of the transmission, this trans has maybe 20k on it and is still under warranty. He told me to come straight there after work finished work heading over to him trans acted normal again. My immediate thought…

99 ats auto , ddrp on frame w/ relay, mechanical fuel press , boost , egt , trans temp gauges ,75 hp injectors ,usually edge ez , but have a so3 also . So been letting the truck set since beginning of the year , while out of state , with overhead camper on , in the CA Sierras thru po1689 , po1698 , po 380 , and po382, had a code reader , Turbo bark , shut down ,on restart erratic idle wont gain rpms I guess in limp mode , long way from home no cell service , walked to a phone and called Cummins pacific in West Sac , Towed it there ,I had dealt with them years earlier with a cracked 53 block and buy parts there , only place that came to mind that I trust …

This was a very heated and debated topic which I'm will to bring back up and report. I'm at 68k miles on the fluid. I've ran for 2 or 3 winters now and have zero issues shifting. Fluid operated greatly in temperature to -35*F and zero issues. I just checked the fluid level and color and it still like it was poured in from the bucket. Clear amber color and discoloring yet. By early summer I'll have 100k miles on this fluid and will check again on the color I might push past the 100k mark if the color is still bright and clear. Now that I'm travelling 250 miles every Tuesday, Thursday, and Saturday hauling @MoparMom to Dialysis treatments in Ontario, OR I've ha…

Happen to be walking by the truck parked in the shop and noticed a small puddle of green coolant. It where its at which is strange. Back at the bellhousing. I know the only freeze plug back there is the block freeze plug but as far as I can see right now there is no coolant coming from that freeze plug but I fear the worst.... Possible head gasket.
