question for both of you guys? 05 5.9 starts beautifully keeps good rail pressure but take the rpms up to 2k and let off the throttle and the revs hang and bounce on the way down. Injector pintals not seating?

As a 3rd gen owner I enjoy these issue trucks an dive into diagnoses and ultimately the fix videos. keep it up Josh. I still have no idea why your channel isn't growing faster cuz you deserve it!!! PS I love the intro on the Dyno when you try to mash the skinny pedal through the firewall!! Ha I guess that's how you get all the horsetorques out!!!!!!

I too am a field mechanic. Many times it's the simple issues that customers overlook. It takes a patient eye to find the simple issues. As to why his channel is not growing faster. Simple answer are the shorts. Seems the youtube algorithm caters to content creators that create those short videos. I've watched it happen to other channels I follow. Minimal growth, start creating one short a week, and subscribers follow.

I've cut a fuel line and welded the end shut to build a cap off the rail. I use it to individually block off each injector to test and drive on five cylinders. This method will narrow down the issue 100%.

Start simple, best advice there is. Is there any decent way to test the injectors without sending them off? I have an 05 with 314k on the odometer but I bought it used with 280k and no idea how many miles are actually on them. I plan to go up in size along with some compounds and cp3 for the future but don't want to wait too long and wash out a cylinder with a stuck injector. The truck runs great but want to make sure I don't miss the signs of a bad injector. Thanks for always bringing great content!

did you ever check the fuel rail relief valve? trying to find a relevant video on youtube that does this. i have a truck that will build fuel pressure, commanded, and actual match up but once you let off the pedal, the commanded drops while actual stays high until the pressure naturally releases through the injectors
@ignacioorozco5080Ай бұрын
hello to everyone I watching this video and I had the same issue the high pressure rail was dropping down I check everything you did and sent the injectors out to be test them and they found out 4 injectors out of the 6 injectors, I installed all injectors and now I have a problem I haven't be able to fire up again after I installed the injectors I monitoring the dired high pressure vs actual pressure and I only getting 22 psi the lift pump is fulling all the way up top off the filter housing, any tips you can give me I will really appreciate it. 😟

I know its something all cr's have in common but is there a safe way of removing the rev hang? being a 3rd gen 6 speed owner it can get annoying in between shifts or even free revving. I've looked into everything and it seems like its just leftover rail pressure. I changed my prv and still hangs... although it returns to idle slightly better.

I drive a 04.5 Ram 3500 around last September it started spitting black smoke out the tailpipe and wouldn’t go over 30mph and it was throwing a code P0148 so I replaced the injection pump and then it wouldn’t start anymore. Took it to a shop near me, they managed to get it to start and said I need new injectors. Brought them new injectors and they kept my truck for 2 months never installed them. Took the truck back from them and tried to install the injectors myself after watching your videos on injector installs. Installed them and my truck still won’t start. The shop told me to crack the injector lines open to bleed air out which doesn’t make sense cause it’s a common rail system. Now it’s at another shop been sitting for a month still not looked at yet. The other shop mechanic thinks it might be the ECM since I replaced the injectors, cp3, fuel rail, prv, FCA, return lines, almost everything. I replace the stock lift pump with an air dog raptor 4g over a year ago before it broke down. Any idea why it will not start after I replaced everything on the fuel system?

I need help! 05 dodge .... started cutting out wanting to die at stop or red lights. Scanned and was told had two bad injectors. Ordered 6 reman'd Bosch 3 year warranty from Thoroughbred Diesel. Installed them. Original issue no longer there. Idles fine. Under a load it runs rough like a fuel ping and smokes. Went through the injectors checking for proper alignment with new Bosch feed tubes. Truck still the same. Changed the oil right after new injectors, thought might have fuel in th oil. Now appears that may have fuel in oil again. Fairly certain I didn't over fill it. But it is over full now. I can't tell from smell if there is diesel in the oil. If anyone can help me I would be eternally grateful!
