  1. hey guys i currently have an issue with my truck, i recently replaced the intake pump and injection pump and it has been fine all the way up until now . yesterday i was sitting at a red light and the truck started pouring out black smoke and felt like it wanted to take off. so i put the truck into neutral and when to put it back into drive then it shut off, it did this about 8 times then i got frustrated and held my foot on the gas and put it into drive and took off. it does feel like its under powered now almost like in limp mode.

    Can crossover tubes cause a slightly rough idle in park and occasional hard starts and not leak diesel into the engine? I’ve tightened the banjo bolt behind the head and the T fitting next to it. I park the truck nose down in the driveway no issues starting. Park it on level ground and every few startups it takes extra cranking for it to start. Injectors are fairly new. It didn’t start right after the injector install. Probably a couple thousand miles after. Thanks for any help.

    I was crawling around under the truck looking for problems and I noticed this cracked mount for the rear of the transmission. I was wondering if anyone else has seen this on their trucks. I searched but didn’t see any threads on it. What’s more, it looks like someone has tried to weld it previously, but it was never mentioned. My dad had the truck for a couple years but other than that I bought it new. The trans was out for a synchro replacement and shortly after that, the 5th gear nut fix. (Whole other story of clown work by a local mechanic). Anyway, I ordered a new bracket and will replace, but just thought I’d post something on it. I was hearing a bit of …

    Code p0260 popped up today. Can’t find anything on it. Any help would be appreciated. My only symptom is surging at 35-45-55 mph. I’ve had that problem before which was just a loose battery connection but I’ve checked everything I could think of and all connections are okay.

    Im having a strange issue occasionally. I have a 98.5 with a 5 speed transmission. When I let the clutch out, the truck usually kicks the throttle up and the truck starts to move without adding fuel from the pedal. It has recently started not doing this requiring me to use the pedal to start from a stop. Its intermittent and seems to do it when the engine is cold. The truck has RV275s and a new injection pump recently. Everything else is stock. Thanks BIll

  7. Just got the truck about a week ago. I will refrain from the steering issues I've had I washed the engine 2 days ago since there was diesel all over (line blew off on way home from purchase) and I like a clean engine compartment. I opted to use a hose with wand power nozzle over a power washer which I use on all my other trucks because I noticed hack electrical work and wanted to avoid any shorting out of components. Well, now I have a cranks but no start condition It started one time for about 15 seconds then died. Did the key on key off deal which revealed the following codes Pcu P1693 Ecu P0236 P0216 P0121 P0236 …

    Well guys, it’s time to change the clutch in my 02 with 103k on it. It held all last summer until I got it to slip up hill in 6th with the quad on level 6. This truck is a summer driver/toy that I plan on building to around 500-550 hp. My brother has an 01 with this clutch https://www.dieselautopower.com/1999-2005-cummins-nv5600-13-x-1-375-single-disc-performance-replacement-ceramic that I’m also considering. However, i’ve read that a factory replacement pilot bushing may be a better option than the bearing. I’d hate to have the bearing fail and pull the trans again. Thoughts on this? Also as far as the flywheel goes, would my best option be to just get it resurfaced? Fir…

    I've been having trouble with my 98.5 2500 for sometime now. I go to start the truck and it "lopes" about 10-12 times and dies. I have no throttle response when pressing the pedal while it does this. I have replaced vp44, crankshaft position sensor, camshaft position sensor, throttle position sensor, grid heater relay, I have newer batteries, also cleaned the grounds really good in the batteries as they had a little bit of corrosion on them. When I turn the switch on it takes a couple of seconds for the WTS light to come on, when it comes on i can hear what I believe is the fuel pump priming. WTS goes off and I start it and it does the 10-12 "lopes" and dies. Any help or …

    Installed a new VP44 from DAP. Truck starts lightning quick as it should when cold. I can let the truck sit for 5 days, nose uphill, starts in about half a revolution as it always has. So no siphon or fuel leaks. However when the motor's warm, not so much. Takes 3-5 seconds but does start every time . But let it set for several hours, cooler engine, no problem. Starting pressure with my Fuel Boss is 20 lbs. Out of curiosity, I put my DDRP back on which also runs around 20 lbs starting pressure. Same hot start problem with either. Is 20 lbs too much? No codes with a good scanner. …

I just want to make sure that maybe a short or something else before I invest in a new ECM. I also have a smarty tuner tuned to level 5.

    Good evening to all I hope you have your favorite beverage and snack for this one as I've gone down a deep rabbit hole trying to bring this truck back to life so here we go! -----Short story, if you are having blower issues and the troubleshooting has basically stopped check the interior fuse panel to ensure you are getting good contact with your fuse, having an add-a-fuse can spread the little keepers inside the fuse holder creating an interrupt at the ignition source for the blower relay (pin 86 I believe).-------- In the process of fixing one of the numerous issues with my recently purchased 2001 Cummins I was at that moment…

    Hi all. Thanks in advance for your time and wisdom. Second gen 24 valve. Quadzilla tuner. No "wait" light and no grid heater in cold weather, but from the voltage drop I can tell the grid heaters do come on after starting, even if the IAT is reading over 100 degrees (I can see what it's reading through the Quadzilla). Doesn't always come on, but most of the time it does when when the engine is hot. Already replaced the IAT sensor and no change in symptoms. Throttle position sensor (already replaced and no change in symptoms) often forgets itself. Have to turn off, back on, press all the way down and release slowly and start. Then w…

    Hi all, so , recently had my fuel pump go belly up and decided to upgrade to an airdog, I know there were a couple options and I was planning on possibly adding power down the road so my research pointed me to the airdog 150. I call the airdog tech support and he recommends the $200 factory replacement with lifetime warranty, I'm game and get it ordered, only while I'm waiting for it to show up I find it's only got a 4yr warranty, and technically isn't a 150, I call the guy back and he admits he made a mistake, what would I like to do he asks? Well, what's my next option with the lifetime? Him; the 4g 150 and you use your stock filter and still don't have to remove g…

    I have a 2001 Cummins 4x4 6 speed manual. With edge comp box. Valair DD Clutch. It has a small lift pump on the frame rail. The filter is an external unit from the LP. Also the previous owner said that it had an Industrial Injection Hot Rod VP44 Injection Pump. It is Otherwise stock. Today when I got into the truck to drive to work it had the Check Engine Light on. So I cycled the key three times and read the codes. They are PCU - P0163 P Done P ECU - P0237 P0382 P0380. I have noticed that when I get into 5th and 6th gear. If I’m not heavy on the pedal that it likes to shutter a little. Like fuel filter is clogged or if your in to high of a gear goi…
