2nd Generation Dodge 24 Valve Powertrain

Im have a charging issue along with the transmission not having od. I checked the blue and green wires at the back of the alternator and the blue wire has no voltage. where does the voltage come from? does the pcm send 12v to the alternator or does the alternator send 12 volts to the pcm? or do both get their power from the pdc where the trans relay is?

I have the Timbo APPS, fixed the previous Lock/Unlock issue a couple of weeks ago. Last weekend I hitched up or 5th wheel for a 3 hour trip. With the 5th wheel in tow, the dreaded Unlock/lock cycling came back, especially later on in the trip when the truck was good and heat soaked, or so it seemed. I have driven it to work (30 minutes each way) this week after disconnecting the 5th wheel, and the issue is again gone. I have previously checked for alternator noise, which was negligible. Is it possible that the charge circuit to the 5th wheel is inducing this problem, or possibly the extra heat in the transmission when towing? Any thoughts would help.

DTC P0122: APP SENSOR SIGNAL VOLTAGE TOO LOW Monitor & Set Conditions Accelerator Pedal Position Sensor(APPS) voltage is monitored when the engine is running. DTC may be stored if low Hi all, I'm new to this issue, just wondering if I should just install a Timbo APPS Sensor and hope that fixes it, or look into other potential issues, or both. If both where should I begin trouble shooting this code? I'm sure there's a writeup in this magical world somewhere if anyone can share any link(s) with me it would be much appreciated. Thanks in advance for any suggestions advise, etc.

I am doing a Cummins swap to a 1995 v10 3500 the Cummins is a 1999 5.9 diesel the truck was wrecked and busted the PDC I can not find one anyone have any ideas

Hi, Installed reman VP44 from DAP, no codes, no problems. But engine now requires excessive cranking to start when hot. It fires right off when hot. Truck has FASS 150 that provides 20psi all day and I've always used a protected isolation relay between ECM and the FP. In preparation for a trip last weekend, and with limited time, I modified my existing isolation relay by adding the NC relay and using the B+ from brown solenoid wire to hold FASS150 at bay during cranking. Moparman has an article on it. No noticeable improvement was seen. I switched to a FASS DDRP-02 I have as spare (circa 13psi) and truck fired right off. Suspect problem is to…

Looking for input, I'm pretty much stock, but hoping to add Quad Adrenaline this winter. I do have RV275's. I won't use wire tap, just Can tuning (or so I think) . The price difference is about $40 dollars, but Airdog states that the difference between the 2 pumps is the rpm of the motor (2000 for 100, 3000 for 150). Will I see any benefit of running the 150 over the 100 with the mild mods I plan. I was thinking the lower RPM 100 might last longer than the higher rpm 150, but I know that engine longevity thinking may not apply to electric motor longevity reality.

I’ll keep this brief since my phone battery is low and it’s 110°. I was driving to San Diego from Tucson when the truck started losing power, throttle did nothing. When I pulled over the truck shut off. Now I can’t get it to start. I don’t have a fuel pressure gauge. No codes. When I try to start it, it just shakes really rough

I got a 98 24 valve I had the dreaded dead pedal. I changed the oem tps to aftermarket ended up being the pump. The ecm was also rebuilt. I have driven it maybe 70 miles and it's back but not a total dead pedal like before but partal. I back probed the tps= 0.35 at idle wot 0.391. At idle it's supposed to be somthing like 4.95. So is it the sensor or is it not getting enough volts?

A few days ago, I experienced a random dead pedal issue on my lunch break at work. I went to go grab some lunch and everything was fine. Got back to the job site and killed the engine to eat. When I went to start it back up, I put it into drive and started to take off through the parking lot. At the moment I started to put my foot on the pedal a little, I realized I had no response. I mashed it and still nothing. Long story short, called a roll off tow truck, when he got there, it worked again. 2 days later (replaced TPS that day), dead pedal again. Reading forums and stuff to find sequences, all fuses are good, CEL went away when I pulled a fuse to test voltage on. Put i…

Before I lay down big bucks for a FASS or Airdog I decided to give the Herko fuel lift pump a try. 1998.5 Ram 2500 Cummins 5.9L 24V. The Herko pump Installed pretty easily. I had to grind one corner off the mounting plate on the pump to make it fit. My stock location is left rear of engine block. My Herko pump did not come with the 90 degree adaptor for the fuel line from tank hook up. It is not needed. I was able to clip my stock fuel line on to it no problem. The rest of the details and psi readings are here in the video. Yep a FASS or Airdog is likely in my future. We'll see how this Made In China Herko pump holds up. I can monitor it with my gauge. I will carry …

I have a 2001 Dodge 2500 5.9l that is stock other than a Predator mechanical fuel pump that I have recently put on. I have had the issue even before I've done any work to the truck of there being brief second of no power and then returning like nothing happened. I will be driving normal (Smooth accelerations) and every once in a while the truck will loose power and go back to normal in a matter of a second. I've always thought it was a problem with the stock lift pump on the side of the motor so i recently replaced it with a predator lift pump and haven't seen it run below 14psi. But even after I did so it still does this intermittent loss of power issue. It can vary from…

Noticed today that when the clutch is engaged (foot off the clutch, "in gear") in any gear or neutral, there's a screeching/screaming noise coming from the transmission I can only assume. Clutch, flywheel, pressure plate, and throw out will be 2 this September/October and if it's the throw out bearing this will be my 2nd one that started by screeching before taking my clutch out. What could it be and if it's the throw out bearing is it too late to save my $1000 clutch or would it be something simple like a slave cylinder? I so think I need a new one since engages and disengages are a little rough...

I am simply going to ask random questions regarding my truck and upgrades, feedback on upgrades others have done....anecdotal evidence etc.... To start off...has anyone ran the stainless diesel manifold? (http://www.crazycarlsturbos.com/Stainless-Diesel-Exaust-Manifold-SDman.htm) If so....what is your opinion on it? I am slowly preparing for compounds OR just a larger single, haven't decided yet. Specific setup is still not known at this point, however I do know I want reliability and usability over everything. In my other thread, TFaoro made some excellent points ( ). I'll be back with more ?s. Thanks. …

What’s up guys? I recently had some issues with my truck which caused me to pull codes on it. When I did that I read the “diagnosis” on 2 different handheld OBDII scanner. Both of them were showing around 13% on the apps or tps. I have tried to mess with it to recalibrate it before but when I do mess with it, it throws a code and the CEL comes on. I have noticed that I have to pushed the peddle further than I should to get the truck to accelerate. It is an aftermarket APPS that is on the truck. Back when I bought the truck I assumed it would solve my ground/ lock/unlock issue. Then I realize that had nothing to do with it and never switched it back to the factory one beca…

I'm new to posting here, but have been reading tons of threads, suggestions, and related story issues here over the past month and a half. I am working on a friends 01 that I cannot seem to get figured out. This started for him last fall with the truck having dead pedal issues, stuttering/miss, and a small hand full of codes. I unfortunately don't have those codes to reflect on now, but the agreed upon synopsis was that the VP44 was on its way out so we made a plan to attack it this spring. Back in April I installed a new VP44 from Bluechip Diesel along with the Airdog FRRP lift pump. At this time I also installed 2 new Interstate Batteries. The truck fired right up…

Full of aluminum, rear seal is leaking so I figure it could have something to do with tail shaft. I bought this trans from All State Gear in San Antonio Tx and it was not a good experience. I am willing to spend the bucks and get a really good trans build. Any suggestions?

hello everyone i have a 2001 24v cummins and am having a lot of problems trying to figure out my dead pedal situation. It all started a couple months ago where I would get dead pedal and a surging in the rpms. I changed the APPS and set the voltage to 0.420v and my surging problem went away but now i have dead pedal A LOT! Iv checked wires and grounds. I cleaned all the grounds and changed some ends but looking at the APPS sensor wiring it looks like the PO spliced in a wire to terminal 3 and ran it straight to the pcm but also keeping the wire going to the ecm. Iv had the truck for 2 years and no trouble up until a couple months ago so I can't see that being the p…

Alright so I might have done something really stupid. I put 2 bottles of the amsoil engine flush in my engine and ran it for an hour on high idle. I did this when I was checking/charging my AC system. I know that you are only supposed to do it for 15 minutes but the only thing in the amsoil engine flush is just detergents, no solvents so I thought it wouldn't hurt anything. After the flush I changed the oil with fresh 15w-40 and a new oil filter. So afterwards I noticed that when I was driving on the freeway @ 65mph, my oil pressure sat at 49-50psi. It would normally sit around 54-56psi but it seems that something changed. I'm around ~1840 rpms when the speed is 65mph. I …

Hey guys looking for some answers on my 99 24 valve 3500 auto. It has bhaf/industrial injection vp44/and fass 150 with big hose lines and in tank sump all installed at same time about two years ago. Fuel pressure gauge is installed about a foot from ip with shrader valve cracked idk if it’s to close and giving an erratic reading but it will idle steady at about 14 then jump up to 18 while driving then all the way down to 10 then back up so basically it fluctuates up and down while driving between 18-10. Another thing that’s going on. sometimes it has a long start when hot sometimes not. And every day when cruising above 65 it will stop accelerating and only give me 30% th…
