2nd Generation Dodge 24 Valve Powertrain

Prior to entering the garage the truck started and ran no problem, mechical fuel gauge worked, and had 3/4 tank, truck is 2002 ram 3500 24v h.o.I've noticed over the summer the old airdog has been dying so I bought a new 95gpm fass pump. completely removed the airdog fuel lines, wiring harness, mounts and everything needed for it. Followed the instructions for the new fass install, I used a pre existing draw straw in the tank to pull fuel. installed the new fass pump, primed the system and hit the key to cycle the pump to push fuel into a bucket, ran about 3 gallons no problem, then hooked the the supply to the VP and opened valve for fuel gauge. Crack injector lines 1,3,…

I’m throwing around the idea of swapping 4:10s for 3:73s to grab lower rpms and higher mpgs. Anyone here ever done it? Is it something that could be done myself or need to be taken to a shop? At that ratio difference is a new carrier necessary? Easiest way seems to swap entire front and rear end but it’s hard to find someone near me with what I want lol.

Hi All,I've been getting occasional 0216 codes since January. Today it took a long time to start and then wouldn't accelerate at all. Idle sounded normal, but it just stumbled when I pressed the pedal. I pulled the codes and got 0253, 0251, 0216, 1688 and 1693. Looks like its time for a new injector pump, and a new fuel pump, and oh yes, gauges.I'm thinking a stock VP44, Air Dog 100 and fuel pressure, pryo and boost gauges. Anybody have any good or bad experiences with any particular vendors? Thanks

Hi guys So I think its time for some new injectors, truck has a pretty decent knock than sounds like all the injector knock videos on you tube. The stock ones have 253000 miles on them so I'm sure the pop pressure is pretty low. From my reading on here it sounds like maybe 100-150k mile per set give or take. So my question is. With a mostly stock truck would you guys recommend RV 275s or the DAP 7V.008 50 HP set or something completely different. Some day I would like to add some HP but nothing too crazy for the time being anyway. They are pretty similar in cost so looking for advise/experiences for other users. 98.5 Standard Cab with lots o…

Hi. New here and I'm glad to find you guys. So I recently picked up a 2002 2500 five nine 4x. 112000 miles. Of course it won't start when hot unless I leave key on till pump stops and then bleed the water filter. I have a Tass one fifty that I'm putting in on tues. there is no fuel pressure gauge but I will be putting one on tues. as well. I guess what I'm asking is my vp going to be shot. Or can we not tell without a gauge. I've never owned a diesel and mine seems pretty week feels like some pretty dead pedal. No smoke on cold start.

I am about to purchase the Raptor 100. I was under the truck today just trying to see what i am getting into. It seems I have a pump mounted to the frame next to the gas tank, which i knew because I can here it come on (and its not the first time under the truck)....when i follow the fuel line up towards the filter it looks like there is another pump mounted on the block next to the filter. I followed the fuel line to this (pump?) and then out of it into the top of the fuel filter. I have only had this truck a couple months and I dont know the history. I am thinking that the original pump was block mounted? And that when someone replaced the pump they just left the old pu…

EDIT, I thought I had a AD-100 when in fact I have a Raptor pump unit. Believe its pretty much the same except without the filters. Have changed the thread title to reflect this. ~~~~Installed an Air Dog 100 on my truck last weekend and while its running, its not running right. Am not at all experienced with diesels (am a airplane mechanic) so wanted to post here to see if there is something that I have missed.The pump "seems" to be working fine. I say seems as three times now its "hiccup'ed" on me. Driving normally (not WOT) at about 40 mph or so the fuel pressure dropped from normal levels to 7-8 psi, activating the alarm on my Edge Attitude display. No difference in th…

my 01 has a smarty/revo and i still have trouble building boost on the line .the tq man is defueling it.i dont want a rad box. can i get a ecm from a 99 or 2000? if i can how do i find the perfect matching ecm?

It was finally time for front rotors and pads so I went ahead and did the 3rd gen caliper brackets, rotors and pads. I've ordered the brake line kit @jlbayes suggested a Russell 694540 as well. All I can say is it's well worth doing! Thanks @trreed for the positive report back after doing the conversion and towing with them...and I "borrowed " your pad comparison picture from your thread.

First off thanks for the add. Looking at buying a 2002 Dodge. Guy said everything is great but one problem. The owner now said you can cruise pulling a trailer at 70 all day but Rpms are to high at 80-90. I found the Guy who built the truck and said you could run 120 no problem before. Any guesses on what may be causing this? Truck is mildly built with a fully built trans. Below is exactly how the owner now worded it I it won't run 80-90 on the highway but I pull the camper 70 all day. It runs too high of rpms in the short. U can hear it hit overdrive but only drops 250 rpms. It doesn't burn fuel I get about 18- 19 pulling. Witn this being sai…

So, when my transmission gets up to 140 degrees or warmer it will not downshift to 1st gear when coming to a stop. I can manually downshift to 1st gear then place the shifter back in drive and it'll work like normal. When the transmission temp is below 140 it downshifts as it should. The only mods to the transmission are a transgo shift kit, borg warner governor pressure solenoid, and a BD Diesel transducer upgrade. I checked the tv cable, but it was already adjusted properly. What could the issue be?

I'm wondering what speed people are going at what RPM. today i hauled a 35' 5er weighing in around 15000lb. and i was paying real close attention to my speed vs rpm.i didn't use OD while towing.2nd gear was 40 mph at 2700 rpm.3 locked was 55 at 2000. in od i turn about 1700 ish and go 67ish. i'm starting to think i don't have the 3.55 gear the sticker on the glove box says i do.thought and imput would be great.

I am running a airtex lift pump and have my pressure gauge hooked up at banjo bolt coming off the injector pump. I was looking and Vulcan they sell a big line kit with a tee that I can mount the pressure solenoid. Just doing a 1/2 inch line from the fuel filter housing to the injector pump- would that be beneficial at all since the rest of my lines are all still factory. What are yalls opinion on this.

so i wanna turn on the cold weather high idle on my truck and have access to a drb3 with all the chrysler software. when i go to turn it on it refuses to connect with the ecm, then i read somewhere it wants you to have the latest update before it'll let you make those changes. so far the drb3 has only been used as a scantool so no one has any idea how to reflash it. from my understanding i need a memory card with the update software on it, but not sure where or how to get it. i also have numerous cds with the title ITIL/ISIS from chrysler but i think these just updates for the drb3 itself and don't contain updates for vehicle ecms. however correct me if i'm wrong, loo…

Any good sources for a HX35/40 rebuild kits out there? I need a bearing kit for the current turbo I've got in the shop. Anyone know of good bearing kits for a fair price speak up and drop a link please.

Oh Boy the document I was looking for... Quick summary of why IP pump and injections fail in Bosch eyes is the fuel lubricity is too LOW!!!! Here you go gang Bosch did testing on USA fuel and don't even come close to the standards of Europe fuel... http://forum.mopar1973man.com/downloads.php?do=cat&id=5

I needed to put the 7x12's on the shelf.I wanted to see if i could get better mpg.As well as help my new vp last a little longer.I traded some guy.He wanted my old hx40.I wanted his rv injectors.So he gave me some cash and the injectors,i gave hin the 40.I sent the injectors just to get freshened up.The guy at the injector shop told me they were crusty.He fixed them up and did whatever them guys do and sent them back. So i put them in.I had hard cold starting problems.Somehow air was getting into the system.I did find the return line needed to be tightened.Did that little to no change.Then i remember the injector guy saying something about (They should work themselves in)…

Did some searching around and figured I would post my experience here. Alot of people replacing the VPs over this it seems like. I went onto the dealer site and found the diagnostic tree for this code. Nowhere does it say replace the pump. It says either electrical/wiring issue which I understand could be the circuit in the pump, or the ECM. Personally I am assuming my circuit board is fine and I have a problem elsewhere. I live where there is an issue with rat damage. My pump is tapped for the Edge. I had a spare APPS to try. I tried the relay swap that moparman suggests. I cant fully rule out alternator noise but i have the BD kit and keep that ground wire r…

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.

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.
