2nd Generation Dodge 24 Valve Powertrain

Last November my original LP and IP failed. Both were replaced at the same time. The LP was a Napa stock replacement. It failed when I got home from a 900 mile trip. I took it to a shop and they diagnosed the LP failed. When I got it back with a new LP and pressure gauge, the LP failed after 2 weeks. I took it back to the same shop, it's under Napa's warranty, they replaced the LP again. Got it back, 2 weeks later the LP failed. Being fed up with the Napa LP dying, I researched online on aftermarket pumps. I settled on the FASS 95gph mounted close to the fuel tank. Got it started and running great. This past weekend, I drove it to pick up a heavy load of wood, th…

Quick question for the experts! Currently working on bleeding my fuel system after installing a new VP44 and some injectors (all from DAP). I've bypassed the relay on my FASS165 because currently i'm unable to bump start the truck with my wiring harness being removed. While having it bypassed I am able to get fuel to flow out of the #5 injector line but that is it, I cracked the lines on #1, #3 as well as the #3 line that connects to the VP also. Does the VP have to be turned over in order to see fuel flow to the other injectors? In my head it makes sense this is the case but I'm looking for input, I hope to have my harness installed tomorrow and maybe turn th…

i just put a resistor in the temp line and now it shifts into overdrive and i get converter lockup. ? is there any adverse affect by leaving it with out changing the sensor and add a temp gauge in pan.should i change it any way and why in your opinions. thank you

Is fluid supposed to accumulate in the transmission solenoid that is attached to the xmsn housing? I have attached the diagram of the connector which plugs into this solenoid, I have cleaned out the plug a few times but fluid keeps re-appearing. Just seems weird that have fluid in a electrical connector. the Main 8-plug connector attaches to the solenoid in question. I did some quick searching and could not find out any information on if this is/is not normal.

So, basically what the title says. I'm interested in mixing and matching bits from a later gen sending unit, in my 2nd gen's. I'm not running any power mods, and lately my fass drp has had intermittent defueling at highway speed. Continued after changing fuel filters. Truck has 370k+ miles on it, big stock, the most recent 150k have been mostly highway.

Ok guys messin with the nv4500 some more and noticed that when the 2nd gear shift collar is slid in to 2nd gear it has alot of movement meaning it is easy to move back to the edge of the teeth on the 2nd gear is this normal ive serched for answers or videos and cant find the answer and would like to know before i put the top cover on

Truck revs up on its own only when under 1000 rpms. When at a stop sign or light it revs from about 800-850 but I think I’ve seen it spike as high as 1000. Code reader shows no codes but key trick shows apps voltage too high. Not sure if it’s the apps though because it’s a timbo and it’s worked great for a few months. And scanner shows throttle at 0% when it revs up.

Can some one give me the torque spec for the vp44 side? I think it's 28ft pounds on the injector side and 89 inch pounds for the injector hold down. Crows foot pretty much mandatory for putting in new injectors and getting the right torque spec?

Just installed a new to me (Reman) VP44 after my old one went out completely. During the install I took out the factory lift pump which was mounted on the block since I already have an airdog 100 on the frame. As well as replacing push rod gasket. Blocked off mounting bracket for old lift pump with a big block chevy fuel pump block off plate (Mr. Gasket #1516) frees up some space and adds a little bling lol. So original lift pump and fuel filter are completely off truck. I go to start the truck after purge all air out of injector pump as well as injector lines. Ive done this before a few months before after new fuel filters but i definitely feel like more fuel was put out…

Sorry if this sounds like a dumb question, I'm doing the w-t ground mod and I'm a little stumped on the alternator charge wire. Maybe it was explained somewhere but I'm just not seeing or overlooking? So, we unhook the original charge cable from alternator and pdc and then just have a short cable from alternator to passenger side battery with a fuse/breaker inline? Question; so no cable gets connected back to the pdc? Why go to the trouble of disconnecting it at pdc and completely removing it? Just cut it and leave it? Am I missing a step? Thanks for any help on clearing this up!

I have a wierd issue that seems to only affect my truck in the morning. I have had a random low voltage map sensor code that didn't cause any issues. So i replaced the map sensor 6-8 months ago and all was well. Lately though it has come back. Usually a few seconds after I start my truck up I get a check engine light but it has taken as long as ten minutes of driving. Some mornings I can drive normally with the light on. Some mornings I get essentially zero boost so the truck is a slug. Sometimes it's jerky, I get a little boost then it cuts fueling I guess because it's back to no power. It always idles fine and even drives fine if you don't have any big hills. The only…

I need the part # for 1999 dodge 3500 pdc or any year that is the same and were could I find one I am doing a engine swap and need one

Hello everybody I appreciate any advice. I just purchased a 2001 Dodge 2500 5.9L Cummings, This truck only has 95,000 miles on it in great condition but it hasn’t been driven very much in the last five years I am going to change oil, oil filter, fuel filter anything else you recommend doing to it. Also it gave me a P0234 code Overboost. When I was on the freeway getting on it, cleared the code it came back a few days later on the freeway again recommendations thanks zev

I'm not sure why one would use this over an air removing AirDog or FASS, but for an ELECTRIC pump has anyone heard of using a Holley Dominator? Only some sizes (100 and 200 GPH) are Diesel compatible, for some reason unknown to me. I think if I was looking for a frame mounted, non-air removing lift pump, I would choose this and the external regulator over the DRP (which I have) or Raptor 100. Anyway, this post is just for bench racing, if you will. Love to hear other's thoughts. https://www.holley.com/products/fuel_systems/fuel_pumps_regulators_and_filters/fuel_pumps/carbureted_fuel_pumps/carbureted_electric_fuel_pumps/parts/12-1800

Trying to find torque specs for nv4500 to bell housing and bell housing to adapter plate.

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
