Just a follow up on installing my new injectors, the whole job took me about 6 hours, I took several breaks being 86 years old, I saved about $2500 doing myself it fired up on the third crank and is running great , no oil leaks, very happy I watched your video. I could not have tried it without your expertise, hope I get many more miles out of it, I tried to attach a video of me working on it..

[@darkirondiesel]

That’s awesome! I’m glad you were able to do it yourself and save some money, thanks for the comment and good work 👍🏻

[@dano8613]

Im in Alaska and despite some things being on par and even occasionally cheaper than lower 48 (3k tranny rebuild vs 6k in missouri) the average rate is $6500 for injectors, lines and rail....i can get all the parts for 2500. Im saying all this because your comment is reassuring lol. I can't justify spending 4k to pay someone lol

[@doomedalready]

Thanks for the great video , I have decided to install new injectors myself, I have great confidence after watching your video seven times.

[@darkirondiesel]

Haha you got it buddy! Take your time and you’ll be fine. Don’t force anything.

[@brenteason9891]

Great video. Love those engines and how tough they are. I have a 2018 6.7L and will roll down my windows to listen to a 5.9L go down the road.

[@wizard_of_poz4413]

I got the same truck but I'm ready to straight pipe it

[@robertwyble5407]

Just finished the install on a friend's rv with 2007 5.9 your video was dead on ,Thank you for posting sailed right through it. Great Job !!!!!!

[@leakypen1]

Thank you for taking the time to make this video, it is very informing and takes the guess work (and stress for the first timers) out of the job. very easy to follow along.

[@metalmann8163]

I have a 2006 dodge ram 2500 5.9L Cummins and right now it sounds more like a tractor but without any power. I will be replacing all of my injectors in the next couple weeks. I'm ordering the injector kit with fuel tubes, fuel lines and gaskets. Very helpful video. hopefully all goes well.

Hey brotha, wanted to say thanks! I did an in the truck rebuild…hone, pistons rings, bearings, injectors, head work, etc. and I bet I came back to your video 20 times for advice and guidance! Badass video! I appreciate it! Keep on kicking ass!

[@leatherneckprepper4477]

The only problem that I have with you is that you’re living in Canada and not living next-door to me so that I can have you do work on my truck for me ha ha ha. You do great videos and have giving me a lot of good advice and I really appreciate you thank you.

[@royagservicesllc387]

Good video. A couple of things to note. When torqueing the injectors, after the initial 44 inch pounds back them off and go hand tight, torque the fuel supply tube to 11 foot pounds, final torque the injectors and then the fuel supply tubes. The injector has some room to rotate in the hold down. This allows the fuel supply tube to better center the injector. The other thing is do not bleed the high pressure common rail. It can be very dangerous and it is not necessary.

[@chrisallen3741]

So would you skip bleeding the fuel rail totally

[@steve5912]

@@chrisallen3741 yup

[@wizard_of_poz4413]

@@chrisallen3741 yeah that's what I always heard

[@erickoennecke3308]

Yes, you skip the bleeding because the common rail fuel system is a self-bleeding system. So, no need to crack an injector line. Like original commenter stated, it can be very dangerous. These injectors, I believe, require a minimum 5,000 psi fuel pressure to pop off and you definitely don’t want that out and about.

[@EricHaskins71]

Im about to do this on my 5.9 and previously I had a Ford 7.3 that wanted to hydrolock if you didnt clear the cylinder before putting in the new injector. Do I need to be wary of this with the cummins?

[@marenboot4535]

These common rails are self bleeding. Cycle the key and let the lift pump run a few times and then crank. If it doesn't start, prime again. It might shutoff but do this cycle over until she runs good. You really don't want to manually bleed the rail for safety. Good luck

[@23Khameo]

Thank you! I’m new to diesels so comments like yours really help!

[@chriscollison3136]

Yeah definitely not recommend to crack any high pressure line free. Karen Boot has it down. If you turn the key on you will get 2 or 3 seconds of run time but then you bump the starter and you will get 25 seconds of fuel pump run time. I do it like 4 or 5 times and the should lite up no problem! Goo video and appreciate you taking true time to do these vids.

[@wizard_of_poz4413]

@@chriscollison3136 Karen boot?

[@PisstNBrokeOffroad]

Working on one right now and I’m used to the old VP 44s where you have to bleed each line spent 30 minutes trying to get the front lines to bleed because I could only get the back three to shoot diesel out but after watching this it makes sense because all the air is trapped in a common rail so you only need to crack one line to get the air out I feel kind of dumb but I’m glad I got it figured out

[@Akusjs]

These people talking about stuff they have no idea what they're saying the lift pump in these are not electronic it is all mechanical besides the ECM the lift pump is mounted with the injector pump. It is gear-driven so which means it is only pulling the fuel up and delivering it to the fuel injector pump which overtakes for the lift pump and provides high pressure to the fuel rail so cycling the key multiple times does absolutely nothing to bleed this system now if you had a newer Cummins with a electric lift pump then this would be true.

[@cameron878]

Thank you for making this video, very good resource to use while I did injectors tonight on my 04.5 ram 3500. The sequence and order was easy to follow and I appreciate mostly the torque sequence/specs on the injectors/tubes. It made the job go quite smoothly tonight. Much appreciated!

[@jaycampbell6569]

Great video, straight to the point and not a lot of rambling on senselessly about the truck’s history and how you’re feeling or any other bull crap like a lot of people do. Thanks!

[@Cdubxxx96]

Just did a set of stage 1 BBI injectors In my 2004.5 5.9 cummins and it was a pretty straight forward job , if I can do it in my home garage anyone with the will power and some brains can do this job

[@Freysz]

How are they holding up? I am in the middle of an install and noticed the new bbi stage 0.1 are not oem bosch

remember in perpendicular its "pounds-inch/foot and for twisting force its foot-pounds. thank you for the spec. 44-89 and 11-37. easy for me to remember

Thanks a million for the video, got my truck back on the road today. One happy camper . Cheers.

[@chrisdavis3642]

Yeah.. gotta say.. really good and to the point!! The only other thing that I can think of is. While or just before hooking up the lines is possibly flushing// or at least inspection for fuel system contaminates. Just to insure nothing but healthy fuel hits those expensive injectors after all the fun of carefully turning wrenches !! Just a thought.

[@leewalker3514]

I just found your channel. I love my old five common rail 5.9 Cummins thank you

[@8lugdrift550]

Lol. I’m intimidated. Haven’t done these before on a diesel and I love my truck and don’t want to mess it up. I know I can do it but I’m intimidated as hell. Thanks for the step by step though.

Thank you ! You made it easy truck now runs sweet again Thank you! Great tutorial.

[@benfouts2164]

This video is awesome my local diesel mechanic retired and we didn’t want to take our work trucks to the dealership and my bosses said fix it lol so I called our old local guy he said to do everything in this video and I’ll be as good as him and I’ll be KZbin diesel certified I’ve always worked on my own vehicle but work trucks are difficult because it used everyday for anything and everything one mistake of out of rocker on wrong it could be a bad day

[@anglersnw]

Asking for advice. I've got a 2005 Dodge, 5.9 Cummins. A year ago I was motoring at highway speeds, let off on the throttle on a hill and got the multi "bell warning dings" and the Wait to Start (WTS) light came on and stayed on. The truck runs fine though. The code that came in with the WTS light is P1222 which points to injectors. With 235K miles on it, I resigned to just replace all injectors. I did so with rebuilds from what I thought to be a reputable retailer. Once installed, along with new feed tubes and also new lines from the tube to common rail, the truck ran the same, starts fine, no noticeable black or white smoke, no loss of power, etc. But, the P1222 code and WTS light are still on. I retorqued all injectors, tubes and retaining nuts two separate times to just a little tighter than stock foot lbs. I performed 3 main troubleshooting tasks starting with the Relief Valve test which passed just fine. Then I tested the return flow from the CP3 which passed within the recommended return flow. Then, I tested the injector return flow (all injectors in place and uncapped). This test also passed with a recommended return flow of less than 180ml. Mine was right around 85-100ml. I tested this twice to make sure. Still, the WTS and P1222 code stay on and the truck runs just fine. I tried erasing the code with my Inova 5610 OBD reader but it will not remove the P1222 code. I also disconnected the batteries for about 2 weeks to see if it would remove the code to no avail. I've since replaced the Pressure Relief valve, Cascade Overflow Valve, MAP Sensor, Fuel Filter and Pressure Sensor. Mostly just to ensure they were not the issue. Still, the truck starts and runs fine. I am wondering "IF" taking it to someone who can "Flash" the computer to remove the P1222 code will only lead to it coming back in or if it is possibly just stuck in the computer and holding me up from using my truck. I don't drive it with all this going on for fear of burning a hole in my pistons. I'm at a loss for not knowing how to fix this truck at this point. Any suggestions would be appreciated. Thanks in advance.

[@ronaldbrosius7488]

You should definitely change that grid heater to a banks!! I've seen plenty of the grid heater nuts rot out, fall into engine and trashing it. The banks one will not allow this to happen. Just do some research and you will see exactly what I'm talking about, it can save you engine

[@darkirondiesel]

The banks grid heaters are garbage and don’t work in our climate. What I’m going to do is the BD Diesel killer grid heater upgrade kit.

In process of doing injectors on my 06 5.9. Bores looked clean so lubed injectors dropped in along with feed tubes and torqued with sequence. Should I take back out and scrub holes or leave it. Everything went together perfect

[@sethhays5525]

On your rocker arm bolts, did you reuse the factory bolts? I tried to reuse them and broke 2 off before they hit final torque. Not sure if that's my doing or if its because they are one time use bolt.

[@Dead-Goldstar]

Awesome video love all the detail for torquing everything down you added do you need to use a tuner after putting new injectors in. I’ll look forward watching more of you videos as well. 👍

[@kipnix8775]

On the #3 injector tube nut. How do you torque it? That electrical plug is causing me some grief.

[@Jackohtrades]

Did you have to change the iqa for the new injectors? Or is that a 6.7 thing? Just changed my injectors last night/ this morning using this video! Super helpful but I seen some people talking about having to change the iqa after replacing injectors. I seen this because a check engine light came on after I replaced them and wasn’t sure why.

Like program trim codes? Is that what you’re talking about? I think that’s just a 6.7 and newer thing.

[@omorin34]

Im having issues with the injector hold down bolts coming loose on a 4th gen. When I took them out 2 or 3 were loose on one side of the plate. I had to go back in due to a faulty injector after a few miles of driving around and found the same problem. Thought about spraying out the bolt holes and using a dab of thread lock. I did install them going back a and forth but it seems odd that some were loose when I went in the first time. thoughts?

Followed your tutorial and replaced all of my injectors on my 06' Dodge 5.9 cummins... now it won't start. I'm sure I'm missing something. When I crack the injector line and crank the engine the fuel doesn't seem to build up pressure although I am getting some air bubbles where I cracked the injector line. Wondering if I'm having fuel pump issues. Any thoughts? Thanks

[@brianz8511]

The cp3 pump is self bleeding.. serious injuries can be caused by cracking injection lines on a common rail diesel. 25,000psi fuel can cut your hand like a laser.

Anything special you need to do before removing the fuel lines because the sticker on valve cover says that the pressure will cut your finger off.?

[@darkirondiesel]

I’ve never had an issue. Wear gloves and safety glasses. Slowly loosen the fuel lines and you should be fine.

[@TimPiebiak]

Hi I installed this way and had a leak inside the head. So according to a cummins install guide at the 13min mark tighten to 44in lbs loosen off then install the tubes, torque then go back and tighten injector to 44in lbs. had no leaks after this.
