2nd Generation Dodge 24 Valve Powertrain

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…

Wanting to change out turbo on my 99 auto , FASS ,edge ez w/ 75 injectors , 4" ex , BHAF , ATS trans w/ lock up control Mainly because of mileage and its time to put a e- brake on and replace my cracked manifold Trying to lower egts towing heavy , Want to stay turbo mt e-brake , and I`m happy with under 400 hp so no h40 downpipe 3 to chose are mod hx35 , k27 ,and s 200 gx-e built by Southeast Power Systems , sold by DAP Lots of info on mod hx35 and k27 , but no info but seller`s on s200 The s200 is like the sxe 300`s in that its a newer design , its custom by SPS Guy`s at DAP are recommending it , anyone ever run one ?

Hi I have a 99 dodge 2500 with 62/68/14, 165 fass, bd exhuast manifold, bank high ram intake horn, edge juice, etc. I just got some 200 hp injectors that I put in to replace the stock ones. I fired up the truck after bleeding the fuel lines and it has a really slight lope/rough idle. This disappears under acceleration and only seems to happen at idle, when I look under the truck it appears that I have a small drip of fuel coming from the back of the block. Feeling the injector tube/fuel line connections they appear to be dry.. I'm a little at a loss as to what's going on

PCM is not energizing the C3 pin 25 blue wire that controls the ac clutch, generator field or trans relay. Had a p1693 “DTC detected in companion module” and no communication with transmission. Had power and ground to pcm so I swapped with a known good PCM but no change. Cleaned all harness connectors and replaced the CKP sensor and CMP sensor. Checked pin 45 on the ecm and there wasn’t + voltage but there there was a ground signal that was all over the place before the meter finally settled at 8-9 volts. Is this supposed to be a pulsing ground or a solid signal? And should it be + voltage? Also how does the ecm ground itself? Maybe a bad ground connection on the ecm?

I store my truck from Nov to March and this year when I took it out I noticed that the fuel pressure was dropping more the normal. I have had 2 separate times that I was letting it idle while unloading it I noticed that the idle sounded different. The last time it happened I was going back to move it and there was no lift pump pressure. I shut it down and then bumped the starter to see if the pump would run and it did with 17 pounds at a idle (18 to a dead motor). I have also noticed that the fuel pressure drops almost 2 pounds more this year under hard acceleration. Being that the pump has been on there for at least 7 years I just bought a new one ( fass ddrp 02). Change…

Hello guys. Long time lurker. I bought a 2002 24v with a NV 5600 about a year ago. The truck had tons of goodies when I bought it. Iv been trying to make it as reliable as possible since I drive it all across the county. Today I am fixing my tappet cover leak with a billet cover. I notice two plugs that are just hanging out with out a home. They lead to the harness the runs along the bottom of the tappet cover. Here are some images. I was hoping someone could help me identify them. My edge juice with attitude also took a crap the other day. It keeps saying “failed to connect” but it works half the time. Sometimes it will fail to …
