2nd Generation Dodge 24 Valve Powertrain

OK I posted this on CF. Thanks Mike for the tip on the Overflow valve. I just finished reading your testing on it and then rechecked to see you mention that lol. Quote is what I posted over there: I did some testing according to the bluechip diesel VP44 diag page and came up with it being a fuel delivery problem. Like I said I only installed a DSV replaced the supply line to the filter, cleaned the prefilter and replaced the walbro with another one, and redid the regulator. The fuel lines used to weep fuel and would drip ocasionally. It no longer leaks but now the hard starting. Used to fire up right away. Not sure if its in the tank, or the new line or? I h…

Ok I have been trouble shooting a hard starting/long cranking issue for almost 2 years now, owned the truck since 2006 2001 24V HO AIRDOG the week i brought it home and ever since Edge Stage4 Jammers I think injectors Newly rebuilt NV5600 (ChaCh$$$ng) 196K nose downhill, no problems level, takes over night nose high, takes a few hours to require a priming sequence necessary to start the truck, worse in the cold weather Lots of informative helpful threads out there and I have been through them all Last night pinched just at the VP44 inlet and just after the T return lines from the head and…

As of lately my truck has become hard to start. It requires about two ten second cranks to fire but then runs great. I have checked for fuel leaks and tightness of fuel components. I installed a lift pump and new lines 9 months ago. Also the tach doesn't match the speed you are driving. At light acceleration the rpms will jump all the way to 2k and on the highway at 60 mph it usually stays around 2700 rpm. I am not sure if it would be the crank sensor since I have no codes. The hard starting just happened out of the blue a couple weeks ago. Any help would great.

Yeah even myself I'm also fighting the hard start in the mornings because of loss of prime in the fuel system. I'll admit when I did the head gasket last time I notices the crossover tubes and the injectors went in rather easy without much force. What I've done so far is change the crossover tube o-rings. I've just ordered a set of o-rings for the injector bodies. I ordered a second set for extras to have on hand for customer rigs. I just rolled Beast back into the shop and started doing an inspection of the head area for weeping and appears to be dry. I really need to roll the power washer out and give the engine a good washing down with degreaser from all t…

My truck is hard to start after sitting even for a short time. I have replaced the washers on the banjo fitting back of the head, the seals on the T fitting, and the fuel line to the tank. I just pressurized the tank with air there are no leaks I can find anywhere. It has new injectors and new crossover tube O rings.still has the same problem. No fuel in the oil. Any suggestions from the experts?

Guys, I have a friend who has intrusted in me to fix his truck. It is a 2001 CTD. This truck use to start when you turned the key right away, hardly would crank over a half an engine revolution and start. Now it cranks two or three complete revolutions before it starts, usually after a hot restart. He lost the factory lift pump years ago and had the dealer install an intank lift pump. He had the injector pump fail shortly after that pump was replaced. I'm wondering what the lift pump pressure should be when the key is turn to run but engine not started. I have none at this time but it starts and has presure of about 7 to 8 psi when running. Should there be initi…

The "Wait to start" indicator on the dash does not come on and the beast is hard to start first time. (The coldest it ever gets here is maybe 60 F at night). Apparently no intake heat happening. This just started happening after a mechanic had it to fix the power steering. Don't see any loose wires in the area. Any suggestions?

I have searched the forum hoping some one else has had this problem but can't find one (4x4 01 3500). I replaced my u-joints that are connected to the front axles about a month ago because I found them loose when doing some maintenance on the truck. Put about 500 miles on it scene then and about a week ago I had a fast vibration on the truck. At first I thought I was on the shoulder of the road and was hitting a Rolled-in rumble strip, but I did not see any rumble strip in the road. It happens when i am going above 40mph and it will last for about 3-5 seconds and seems to get started when i hit a bump or a recess in the road. I live in Newport Oregon and commute on Hwy 10…

Hey all. I have been poking around different threads asking questions but I figured this is a big enough problem that I should start my own. Over the last month or so I have been having a problem with my batteries running dead in short amounts of time. I blamed it on the cold and put 2 brand new 850 CCA batteries in and changed out the alternator after having the light come on multiple times for it. I was having fuel gel issues and left it parked overnight (the block heater WAS plugged in) and came back the next day, batteries were to low to crank over. I know for a fact the block heater is working correctly, block stays nice and warm in the -30 weather we have. I…

Everyone,Well my truck has done this for a little while, but thought I would ask and see what people say. The truck starts great in the morning everytime. It seems to mostly do the harder starter (when it has to crank a few more times to start) when the engine is warm. I'm going to start to watch and see if that is a rule with it or not. The VP is new for the second time on 7/23/2010 from Midwest Fuel Injection. The first one was replaced on 1/11/2010. Fuel pressure is good, no codes and the truck runs great otherwise with high 17s or 18s mpg on average. Any thoughts guys??:shrug:Also I should say it did this a few times after I put the new VP on, then I tighten the injec…

So I installed new Clutch and now it has a small drive line wine. Nothing serious just noticeable. So I ordered the Fluidampr harmonic balancer from DAP. Anyone hear using one? Yeah I know should have asked first. lol

Hey guys, While the engine is running, noticed the H-balancer has a slight wobble. Feels tight if i tap on it, but looking like some rubber pieces may have broken off. Otherwise runs smooth. no noticeble vibration beyond the normal diesel cummins clatter we all know and love! Are these known to fail?

Okay, so I gotta get the dampener off to fix my crank seal. I do not remember it being so hard! I do not have a barring tool and it would be 4 days out at the earliest. I do not have that kinda time to wait. Is there anything I can do to break the bolts free?I thought about whether or not I could put it into Drive and break them that way. Would that work?

hey guys. So I was scrolling through a Genos catalog and came across the dampner for our trucks. I got to thinking about what the signs of failure were, and did a little research. Looking at mine, I see the rubber has been squeezing its way forward and looks to be getting old, 260k miles, but when idling, it doesnt wobble off balance at all. By comparison, my dads 99 looks really good, almost newish. I don't know if it was replaced at some point, but he's had the truck since 02 I believe and hasn't replaced it himself. As they fail, I've heard you get more vibration through out the motor, but sometimes its real gradual that you may not notice it over time. If…

It never stops, one thing gets corrected and everybody is happy until the next mystery shows up. The 1999 Dodge Cummins 2500 was doing great once the fuel leaks were taken care of. After a few days my brother called me and mentioned a strange harmonic sound coming from under the hood at start up and then fading out once he started to drive. Well the sound has gotten worse and louder. He sent me a recording of it that I could hear with ear pods from my phone. It sounds like a tuning fork. All the belts are good, the belt tensioner is good, fluids are correct, no clamps loose or tears in the boots. I went online and put the description in on google and had some similar soun…

I am hooking up boost gauge today and couldn't find steel so I got 3/4'' to 1/2 and then 1/2 to 1/8th to hook up my boost line to gauge. I was hoping some of you would say you have done this with no problems but if you think its going be a problem please let me know. Thanks in advance. CD

First new to site. I have another vp44 question (sorry). I replaced my vp44 back in oct 2011 and also added the raptor frrp pump and i made a big line from fuel filter to vp pump. both were purchased form thoroughbred diesel. At the time i was working out of town and wife was driving it when it did not restarting in the wendys drive through. so i had her tow it to a diesel shop to be looked at. them came back with needing a new vp44 pump. so i order the parts and installed them, got the truck running and drove it 20 miles or so. Got home it sat for 30min and went to start it and it took way longer then normal. So i thought the pump might be making to much pressure so i…

Well I can can show you with 2 pictures I got from another member over on CumminsForum.com.The ECM circuit board is folder in half inside the case frame. This first picture has all the 50 pin connector that is facing the fender.I the next picture down toward the bottom edge you can see the processor, RAM, PROM, etc. This half is facing the engine.

Just bought my truck in May, 2002 3500 quad cab, it's the first diesel I've owned, so I'm on a definite learning curve here. Truck runs great, starts right up every time, pulls the 27.5 ft 5th wheel no problem. But here lately in the afternoon when I get off work and crank her up to go home, she'll idle out of the parking lot and when I get to the street and hit the throttle...... nothing happens and she just slowly creeps into the roadway. This will last for a couple of minutes and then all the sudden she'll take off and run great all the way home. I read some earlier posts on how to read the codes and so I read them this evening, here is what I got: P0500, P0460, P1693,…

What all is involved and what would a person be looking at cost wise?
