- I had to change out an injector on my truck but I was unable to find any videos online showing me how to do so before I knew what I was tackling, so I decided to upload a video of my own explaining how to change injectors on the L5P to where are you know what you are getting into. I hope you find this video useful! Find Me on Facebook messenger. / jameskieff
Incredible video skills being able to do one hand mechanics work with out cursing like a sailor. Mad skills and patients.
Thanks man!
Appreciate the help. Just did #2 and your video was the only one I could find.
Thanks for doing this. Not the nightmare scenario i envisioned.
Hey brother thanks for the taking the time to do this video!
Thanks for taking the time making this vid👍👍👍
No problem! I hope this helped you out👍🏼
Excellent video great job
Bro thank you! Excellent step by step and we all know you didn’t have no help lol. Thanks
Thank you for understanding man! I tried!
Thanks for this video. I learned a lot from it.
Thanks bud. Appreciate the vid.
I use to own a GMC LML Duramax. I loved the truck, engine and transmission, but I don’t miss the maintenance i.e glow plug issues etc. Damn modern diesels. I now has owned Toyota Tundras. All I have to do is get in and drive. Never have to go under the hood for nothing. NO it’s not a 3/4 ton but it will get the job done with no issues. Best truck I’ve ever owned.
I agree Toyota’s last forever, I owned one for about 3 years. Now with my commercial fishing boats it demands me to have a diesel being they’re 18,000 and 23,000 pounds. They used to be poo on fuel but it looks like the direct injection handled it a good bit better
17:23 how to remove injector without special tool. Thank you sir.
Does anyone know if it is necessary to program or code these injectors or if they are just installed and done?
Thank you. Just got charged $2500 to change #6 injector. Wish I saw your video first. What did parts did you use to delete/tune it? Again thank you I'll do my own injectors now.
Thanks you I’m currently having an issue with the number 7 injector
What is the name of the tool that you used to pry up the fuel injector? I really need it for mine
Thank you 🙏
I'd have some new seals on hand that seal up the return line banjo bolts. Those little bastards can be pretty elusive when you take the bolts out. Also, would be nice if someone would post the torque specs for this job. I'm still looking for them as they're not easy to come by.
Awesome Video! Thank you! Just got code P0204....guess its time to replace it.
My 2019 has a P0204 code saying misfire #4. I am hearing this could be the harness or the injector. I took this to the dealer bc I have 70k miles on it. Shouldn't this be a warranty item? They are being very wishy washy.
The engine will be fine unless your towing heavy a lot. They changed the firing order from the LML to extend mileage from the crank breaking with the L5P but crank failure still occurs.
We got a L5P with 120k on it with a broken crank that happened last month and lost 3 LML in the past year. Way to many failures for towing 14 to 16k .They break on the 1, 2, and 3 journal.
Wait until you have to change a turbo or egr valve, you need to pull the cab. The Gassers are worse with the 6l80/6l90 tranny failure rate. We lost 39 in our North American Fleet. Lost 2 of the 5.3 engines in 1500 that tow nothing. The best option is to repower them with a Cummins just my opinion. Right now I'm really beating my head off the desk since our fleet is switching to ford and
I'm a ford guy but the 6.7 ford failure is even worse. the engines are on back order due to them locking up. The Dodge's you need to purchase a new front end and keep it in stock but the diesel
cummins is the best on the market. and ball joints take about a hour to replace if you have the correct tools. Myself if toyota ever came out with a Diesel that would be where i'd invest my money.
Take it or leave it just my 3 cents worth.
My 2018 duramax just had three injectors go out. Would you just change the three injectors or go further into the fuel system?

Great video! Thank you makes me more confidant if I decide to buy a L5P 2500. I’m confused about the part of its not deleted, so I have to buy a tool to code the injector to the ecm? If so could you tell me what tool to buy or if there’s another way around that part?
Dealership does an injector relearn procedure for a flat rate of like $130
Because the EGR would be in the way of the injectors on the passenger side, I’m going to be posting a video in about two weeks of the delete process
@@jmkieff Thanks man, I really appreciate and enjoy the videos. Gives me confidence in staying with GM which is where my heart is, I was seriously considering a Cummins just for the ease of working on the engine. But these videos show that just because these new engines look intimidating they can still be worked on at home.
@@richardpreston6078 absolutely, they are intimidating at first but once understood it is just another Diesel engine with a ton of potential
@@user-px5fo7jd2u Dumb question here, but I’m new to the diesel scene- So after an injector is replaced, will it start and run long enough to get it to the dealership to be “relearned”? Or will it have to be towed there? Just trying to figure it out now, before it actually happens! Thanks
Let me ask you a question I have a 2020 l5p when your injectors went bad was the truck shaking as in a rough idle ? at a stop or in park ?
Yes that was the first dead giveaway
What scan tool do you recommend for coding the injectors prior to installing?
I like the edge monitors but BlueDriver works good as well
@@jmkieff I didn’t realize the blue driver had bidirectional features available for the l5p. I thought it was just a code reader. Can you code injectors and do stationary regens on the l5ps with this tool? Thanks in advance for any information
My guess is that you had an imbalance with injectors 2 and 8 ?
Also what was the mileage on those injectors?
Was there any issues that you noticed, miss fires, lack of power, bad fuel mileage that you noticed that had you look at the injector balance?
I was having a shake in idle, and I knew 8 was bad for sure but I changed 2 just because that balance rate still wasn’t right after changing 8. So I swapped them both at 60k miles and it’s been smooth since
So what sounds was it making before you swapped the injectors out?
While I was in the cab I can feel it shaking from the missing cylinder and when I was by the exhaust I could see it shaking an awful lot and hear the slight pause in the firing order. More like a small lope
On the passenger side at least one of the injectors can be done by taking off the tire shield, I think that maybe injector number 7 not totally sure, lots easier than trying to do it from the top, hope this helped somebody.
I’m surprised you’re having injector problems so soon on a 2018 Chevy. How many miles on the truck?
I have a 2018 GMC
What caused the injectors to fail?
Why not change them all?
Thank you for making this video
It had about 75k on them and I don’t know honestly it’s just luck of the draw
Where did you purchase the new injectors from? What codes were you getting,any smoke from the tail pipe or running extremely rough?
I just ordered them on eBay honestly. And there was no smoke at all, the injector was just failing to inject fuel at idle, only way you get smoke is when it’s stuck open or failing to ignite
What all do you have done to this truck, what do you think caused the injectors to go bad
In my opinion it’s nothing that I did to the truck because totally stock engines have the same issue. And then it’s only a 50-50 chance the dealership will warrantee them and wants to work is done if they do not warrantee it it will cost you about $3000
Oh shoot partner I didn’t think it was anything you did as you look to be someone who works and takes pride in your truck. I appreciate the video as it looks like it isn’t too bad to change injectors on these L5p’s. What all do you have done to your truck
I have a 2018 that I’m pondering putting on a diet lol
Thanks for taking the time to make this video, however, we can't see a majority of the work you are doing because of the camera work lol
Sorry I was by myself, doing a delete video in a week or two.
@@jmkieff all good bud. This video helped me tremendously! We appreciate it!
Do these injectors have to be coded or preprogrammed or is it just plug and play?
If it’s deleted just plug and play if not then yes
@@jmkieff thank you
Can anybody recommend a reasonably priced scan tool or monitor/tuner capable of coding e or programming the injectors?

Glad I got the extended warranty and then it's bye bye!
Tbh a lot of times the dealerships won’t warranty injectors when bone stock because they claim different things all the way down to them being Denso injectors and not a gm manufactured product
How much was for the delete
Sorry for the late reply and $4900 in parts
You need someone to hold the camera for you. Can't see jack
nobody has a 10mm socket
Anthony Caltagerone it took 17 of them to make this video I feel your pain
Truth!
That was the cold side
Driver side is definitely the hot side, passenger is the cold side. Hot side is metal cold side is plastic from the factory.
Injector #8 is evil incarnate
Good video sir. Subscribed! I have a channel with L5P content as well. Check it out!
Scott Link thank you man! I’m on your page subscribing as well!
Only been at it about a month or so. But I am enjoying it. It’s cool and inspiring to see other people just starting out like us.
Scott Link absolutely, I want to make a video on a delete too because I haven’t seen an injector video so I made one and I haven’t seen a delete one yet. I deleted mine a year ago and didn’t video it but I’m waiting on a customer to pull the trigger so I can make one.
I’d be very interested in that. I want to do it. But it’s $$$$
Scott Link yes it is, it’s actually cheaper than when I did it by about $1200 but very worth it
