    I got a 2018 Cummins with 60k miles tuned and deleted, never had any problems with it tell it was struck by lightning. Took it to a shop and they pretty well replaced everything injectors, turbo actuator, wiring etc. I’m having problems with the exhaust brake, when it’s engaged it says it’s...

    Been chasing this issue for a while, it happened all of a sudden while driving. I’ve replaced stock LP with Dieseltuff’s HVLP. I ran a direct fuel source into the LP to eliminate the possibility of air getting through. FP reading after filter is 19-20 PSI. Truck was also running on very...

    Hello, I recently returned from a deployment to Korea, I was there for 12 months and my truck sat here in the states while I was gone. Although my parents went and started it a few times while I was gone, when I returned I started it, and it ran for about 3 minutes and then blew some white...

    So, after not realizing I had a hole in my fuel tank and driving around with the water in fuel light going on and off for a few days the truck started to idle poorly when letting the clutch out but would perk back up when I gave it some throttle but still had no power. I was driving the truck...

    Hey all, quick question. Just had the injectors replaced and the valve retimed in my 06 24v. Got new 25% over injectors from DAP. Was wondering if there is a break-in period for new injectors? I seem to be having excessive white smoke on cold starts after it sits for a while, but it goes away...

    I have a 2010 Ram 2500 that is fully deleted. I was having some tune issues so I returned everything to the stock tune. I haven’t had a chance to get it retuned yet and it doesn’t go into limp mode. I drove on the highway for a while and when I came to a stop light there was a pretty good amount...

    2006 ram 2500. Few months back truck started smoking when I'd start it up, white smoke once I start driving it goes away. So I pulled the Injectors sent them to a fuel shop here in town. They cleaned and tested said they all look good. Put the injectors back in still doing the same thing. It...

    Just bought this truck about a month ago. 2006 3500 mega cab, 5.9. Love it to death! Previous owner has done quiet a bit to it. I'm not 100% sure what all is done to it since i bought it from a dealer. But it is straight piped and has open air filter. Motor is super clean and i can see studs, so...

    Hey so not too sure what the problem is here might need to take a look but here’s the issue. I just bought this truck bout 2 months ago and the guy said he put in new injectors in April and had reciepts.

    I recently rebuilt my engine. .20 over pistons, new cylinder head, bearings etc. —Reason for rebuild: blown head gasket/cracked cylinder head. -After my rebuild I started the truck up and noticed a constant white smoke from the exhaust. The truck also sounds different then before the rebuild...

    Hello my Cummins friends. I recently bought some injectors off rockauto (ultra-power) as I needed some new ones and was having trouble finding a set that aren't rebuilds. So I figured I'd give them a shot. They came with the new style of connecting tubes. They were installed by myself and a...

    I took my truck on a trip with the wife and kids and truck camper, ppump was leaking oil near the afc due to crack from putting a bolt down a bore with pre existing broken bolt inside. Was managing but this trip was the last straw leaked a whole bunch of oil, on way home had to make it and had...

    Working on a early 91 Non-IC D250 showing 140K miles that sat for over 10 years baking in the AZ sun. After replacing the injectors and lift pump and resealing the injection pump the truck blows quite a bit of white smoke, misses and has high fuel consumption just idling. I've got the fuel cut...

Truck is...

    Hey y’all, the other day I got a CEL and code PO191 popped up which is “Fuel Rail Pressure Sensor A Circuit Range/Performance” and today I just noticed whenever I accelerate hard it blows whitish grey smoke instead of black like it normally does. It’s 2g swapped, and it used to roll black...

    Got an 08 6.7 with 134k miles. I need some help, I’ve looked at countless forums and couldnt find a good enough answer to my problem. Recently started blowing black smoke when I jump on the throttle and downshifts from a higher gear. Almost seems like it not getting enough air right away to burn...

    Hello everyone. I am still having my knocking issue and with my last post the KSB was an issue I attempted to fix. I'm only getting 11.8 volts to it. not sure if that is an issue. New fuel filter and new fuel. adjusted the valve lash. I really regret doing it without noting which were a little...

    This truck has got me stumped, I’m having a few issues and would appreciate any insight! So if I start the truck and drive it when the engine temp is below 100 degrees( pretty much when I get in and go) I will get a big puff of white smoke only if I get on the throttle hard( like floor it) it...

    So I have an 89 cummins and I bought it knowing it needed some love. Had a slight knock, not very hard, but noticeable. Also had a white has and when you gave it some, it blew white smoke. So I changed the injectors to ducky fuel injection 5x.012. Well the knock did not go away and neither did...
