2nd Generation Dodge 24 Valve Powertrain

So this is what is going on 2001 banks exhaust, hi ram,Quadzilla xzt, RV 275 injectors brand new Bosch, fass 95 big line,. Had code1693 never found out what it was it was getting a little slow to start sometime had dead pedal sometimes and stalled sometimes. Replaced vp44 industrial injection so. Starts great but seems to idle a little rough little. Today I had dead pedal. Oh and 1693 code is gone now fuel pressure is always 17,18. Seems a little down on power would it still run if I jumped a tooth on the new vp?

WTS Lamp will not come on. Truck still starts. Manifold heaters do not come on. Has a hard time starting in the cold without block heater(start up) Runs good. I usually wait for instrument light to turn off before starting.... WTS LIGHT has not been working for 5 months. Any ideas appreciated... I let it sit for two weeks. Batteries went dead. Tried to start and the lift pump stayed on. Charge the batteries and that problem stopped.

Doing research the past few days and was intrigued by the Xotic studs, mainly bc I think ARP is overpriced. Tried to reach out to Xotic, but they have no live phone support. Used their online chat support and talked to “David” in the Philippines. Asked “David” a few questions which were answered with links to the Xotic website, then asked where the studs were manufactured and David abruptly ended the chat. I was able to track down the parent company and CEO information, but by then I’d made up my mind to buy the proven, and American made ARP’s. Btw, the parent company address on Google earth shows up as a muffler shop at an industrial park in eastern Canada. Xotic might b…

i have a xzt xzillerator tuner trying to re flash but win 10 wont recognize the tuner does anyone know a work around for this without sending it back to quadzilla i dont have access to a pc with xp

She runs like you anit never seen, boys I am going to be hitting 19 mpg I just know it for a 9800 lbs truck. It runs so smooth you dont even know it's running, sounds like a electric car it's so quiet. 2 Years of misery man finally over, next I be hittin the rollers LOL.Sorry for all the excitement, I just cant get over it's finally done. 1 Million miles here I come. Well only 750k left to go.

I have been having a new clunk for a week or so now, old clunk is still there and will always be there. I figured it was a ujoint. Well it was, the rear most joint Good thing I didn't hook up the horse trailer for this weekend yet

Can the main computer shut down the Bosch VP44 if there is a cooling problem or temp sensor error? I have been having cooling problems on hot days and under load. After flushing radiator, the engine ran normally for 5 minutes down the freeway and then suddenly stopped and wouldn't start. (as if it ran out of fuel) . Fuel pressure from lift pump is OK. Fuel to the injection pump inlet OK but nothing at the injectors. There was no missing, no smoke, no roughness, good 23 mpg, just before shutdown. Coolant temp was normal. It seems odd that the VP44 would fail after I was working on the coolant system. Is there an internal fuel shutoff solenoid inside the VP44? …

I recently purchased a used transmission which worked fine when he pulled it out to convert the truck to a 5 speed. After getting it installed in my truck and getting the fluid level correct and everything adjusted properly, I think, I have no overdrive and no TCC lockup. The TCC will lock when I flip on my mystery switch but not under normal driving with the switch off. After driving the truck for approximately 20 miles I had a couple of pretty steep hills to go up on a side street in town. The trans seemed like it was slipping the entire way up both hills. While climbing a longer hill on a backroad I started up the hill and everything seemed fine and I noticed the engin…

Hey guys I hope you can answer a simple (hopefully) question. Lately I've noticed my pressures dropping on my DDRP. I did some research and didn't realize there is the infamous ball and spring pressure relief in that model as well. So I stretched the spring out a 1/4 inch like most recommend and now my pressures are pretty high. At idle I'm around 24 psi and 17 at WOT. Is 24 psi too high for idle or is it OK? The ball looked to be in great shape unlike some of the deformed pics I've seen. Thanks in advance. D

my fuel PSI is 15 Idle 11-13 WOT..meaning on a hard pull it may pull to 11psi for 2-seconds if i get on the pedal hard like to pass something then it snaps to 13psi..I lost a 1-2lbs when i replaced my Fuel/Water seperator w/ the AirDog updated one, .."which is a Luber-Finer' FILTER and i was able to get the # for from "STANDARD LABATORIES" If any one wants it

Ok, I thought my vp was shot, now I'm stumped. I posted that I was given an 02 QC which had been sitting for 2 years. When I got it started it ran rough, and smoked like a train (white smoke.). Last night I changed the fuel filter (which was black), and noticed the little "o" ring around the cap was missing. MMMM... So I put the new filter in, along with the new "o" ring. Fired it up, and it quit after 2 seconds or so. It lost prime. After bleeding it, the engine ran like new! When I revved it up, there was a little puff of BLACK smoke, but NO white smoke. So I took it out for a drive. Turning at the corner I got into it, and it lit the tires (buckshots) while getting g…

I have recently bought my first Dodge Cummins, I have been a ford guy prior and am retiring my 1993 7.3L F350 with 330k miles on it. Anyway my pickup is a '02 4X4 5-Speed, all was well for the first week or so that I owned it then it started to the this surging thing, it usually surges between 1500-1900rpm, under load, like accelerating or going up a hill, sometime way worse than other times. [*]I don't show any error codes with the ignition switch way of looking [*]I have reset the APPS [*]I have cleaned my grounds [*]Happens while both while using cruise control and not using cruise control Seems like a Timbo APPS has fixed things similar to t…

There's a guy selling a VP44 pump tester on a local classified site. He says it eliminates the ECM and wiring and will run the engine from the tester. He's only asking $150 for it. I'm wondering if it may come in handy one day. Could even use it to run an engine on a test stand.

I'm still having trouble with my ScanGauge but wanted to make sure I understand something correctly. In order for Average MPG to be displayed as a gauge, I have to program it with Xgauge? I'm talking about average mileage on a tank of fuel not the mileage for the last 2 seconds that shows up on the gauge as MPG. If I toggle through the gauges, should I find one that says AVG?Thanks guys.

I received the 'dread' P1688 - but when reviewing the various threads, it is often accompanied by a number of other fault codes and usually the poster is stating that the engine won't run. My CEL came on ....but other than a code that can be reset (engine off) - but returns when engine is running - the truck drives and the VP pumps. I expect I will have to replace the VP.....but I don't want to rush and replace it if there might be something else to check and maybe something else might be the problem rather than the VP. I did read discussions about alternator problems where a bad (shorted) diode could create an AC component on the DC - and 'fry' electronics. I checked …
