Thank you so much for all your videos. You have saved me so much time and headache over the years. Yesterday I threw P0204 and was rattling like hell on the interstate with the emissions service and check engine light coming on. Limped it home. Watched this video. Ordered the part on Amazon and it was here 10am this morning. Two hours later I was done. Hardest part was the fuel line disconnect. I found the trick to be the plastic round disconnects from Napa. Much appreciated Mr farmer. I will buy you many beers should we ever meet one day. Now I have a spare connector with me in the truck at all times.
I should also add I was at 78k on a 2019 Silverado 2500hd and this was my first one I had to replace
I had a #6 cylinder go bad. His commentary all the way through was spot on. I got the special tools for the fuel lines, a new connector, did the pre work like he explained and my problem was fixed! I saved a TON of money. Thanks again.
Thank you! I'm really glad the videos helped. GM should be doing something about a solid permanent solution for this issue but i haven't heard of one. I keep buying the GM connectors. I have replaced #7 twice
Just watched this video today and followed along to do my number 4 harness. Tripped po204 and 304 codes and emissions bs came on with partial limp mode. I did NOT take my inner fender off. It was easy to get at everything from the top drivers side of engine. THANK YOU FOR POSTING THIS VIDEO!
Thank you for the comment. I'm glad the video helped
Hey Farmer, I’m gonna have to do this to mine I threw the codes this weekend, but in the video you said number one is the first one and number two is the second one isn’t that 2,4,6 and eight on the driver side..?
I need to do number four which would be the second one right like you did in the video..?
I got the shudders and shakes on the highway earlier this week.. scanner gave the code and we watched this video on the way home. Changed it out in about an hour after we got the right part. This was gold.
Used this video to change the #4 connector on my 2017 @ 115K. Was very instructive and followed your video step by step. Got my connector as you suggested and it looked exactly like factory connector. Many thanks for taking your time to do these videos to help us keep our rigs going at a reduced price!
Thanks,
RJones
I'm glad the video helped and you got it fixed up
Where is#4 located
@@BrightthgirB Drivers side second from front
@Ryan Mills Thanks, I replaced #8 by accident and then realized I replaced the wrong one. I replaced #4 right after. Thing is working better than ever.
Another great video. Broke down in Cheyenne with p020D. Followed your video and got her back up and running. Thanks Again!
Good deal, glad the video helped. Thank you for your comment
Just did my 2019 today, #7. Worked like a champ, thanks for the videos, I would have changed 5 while I was in there if I'd read all these posts before. Hopefully it will be awhile before the next one. Truck is smoother than it's been in a while, I think it's been intermittent but not steady enough for the reduced power thing till this morn. Keep posting!
I'm glad you got it fixed up!
Nicely done and very well explained as before! Thanks for sharing this with us.
Thank you! And thank you for your comment!
Haven’t had an issue yet but great to know what to look forward to whenever this issue decides to surface on my truck.
You do great job explaining I own a. big truck but enjoy your content as I am doing my 10. I bet you miss the room to workwith. Understand your operation.your patience is most important. I understand road side patience is hard.. be blessed and get home safely. I do look for your truck as I bounce down the raod.
I do miss the room but still enjoy the change of pace. I'm glad you enjoy enjoy the videos.i know i searched for info on the connector replacement and found a few that were vague so i wanted to do the best i could.... but it's easy to leave things out or get aggravated trying to video when having issues. I just hope it helps someone out. Thank you for your comments and stay safe.
C Farmer thank you sir for your video it help tremendously changed out my #4 injector connector 👍
Thank you for your comment. I'm glad the video helped
Nice video on changing injector connector. Thanks
Thank you!
Man, your gonna have to replace all 8. I've got a 2019 3500 and I've replaced 1
3,5,6,7,8 I just ordered the rest and im about to do them all. Apparently there's a law firm out of Chicago going after GM over these connectors. Hopefully, it triggers a recall.
That'd be nice if it did. I've ordered extras
How it go my injectors just failed n I took it to the Chevy dealership in Dallas
Good video bud and a lot of good info. Keep up the good work
Thank You!
You are Awesome thank you so much for your descriptive and well taped videos
Thank you for the awesome comment!
I was able to fix my truck today because of your videos thank you again!!
#Injectorconnector #8
I'm so glad the video helped and thank you for the comment. Comments like yours motivate me to make more videos. If i can be any help just let me know
Just did it thanks a lot the video was top notch
Good deal, thank you! Glad you got it going
Another great informative video. Appreciate the great videos. Oh, by the way I went out and purchased a Bakflip cover for my Big Dawwg.
Thank you! I hope you like it as much as i like mine
I don’t usually comment but this was a great video.. subscriber for life!!
Thank you, that means a lot!
I have a 16 LML and I believe I have this in my future.. every once in awhile I get a little “misfire”/ hiccup driving down the road. Not severe enough to light the check engine light yet.. but im sure it’s coming very soon.
Thanks for the video!
I hope it's something simple for you
Man just buy the supplies and throw them in the truck now 😂😂😂 because you already know it'll go out at the worse time possible.
So here we go again!!!! 36 miles after changing number7 plug (C farmer coaching all the way) the truck does the same thing! pulled over on the freeway sat there for a minute (believe small stroke and heart attack all in one) scanned the codes and won't you know it #4 injector bad! 8am in down town Kansas city on the freeway FML. Cleared the codes took the next exit. headed right for the dealership to get a pig tail. (I had ordered one online already for a spare I didn't know when it was going to arrive. Turns out Chevy is cheaper then GMC on parts that are the same.
Watched the this video again thank you!!! I also read some of the comments. based on this I had a plan. I did not pull inner fender well . first step front 10mm , hot pipe ,fuel lines ,rear 10mm remove cover (hardest part of entire job) replace plug reverse order.
So I kind of took it as a challenge when I read that you thought you could do it in and hour. kept my head down (and it was to early for miller lite) 47minutes start to finish. I am pretty sure you could beat that lol.
On a side note I talked to the Diesel mechanic at the dealership. He said replace everyone you can get to when you have it apart. they are all going to fail!
Thank you again
While i hate this is a issue with these trucks i am glad you got it fixed up and I'm so glad the video helped. Gm should be ashamed for not recalling and fixing this issue. I have done #7 #4 and #5 on mine and keep a spare in truck at all times. It's a pain but i still love the truck. I hope that's your last one and it does you a good job for a long time now
@@CFarmer I have the one mentioned coming. I have also started the tool list I will need for out of town trips. I got to quite watching your videos my wife is going to kill me making upgrades LOL I am 36 minutes into the 300K overview and I am pretty sure I am a couple thousand dollars in the wish list
I keep a spare connector in glove box. Keep in mind it took me 2 years to accumulate my toys so slow and steady but make sure to keep wife happy first. I'd trade all my toys for a good quality sandwich maker, 😆
when releasing any connector like that give it a push in, push the release button, then while still holding the release button remove the connector.
i m learning alot
Just replaced mine, took me less than 2.5 hours including watching this video and a few others. Hardest part was getting the injector cover back in place. Next time it will take less than 2 hours. This video was excellent to show the job start to finish.
Another video that assisted with getting the fuel lines off that I was struggling with - ruclips.net/video/LnFDRwVmDNU/видео.html
Dealer told me it would be under powertrain warranty at first, but when I called to confirm before appointment they realized it wouldn't. Told me 4 labor hours plus part, so about $900 for just the #4 connector.
I'm glad the video helped
I just did this today off your vid thanks
I have A 2018 6.6 with a #4 injector open circuit so I'm going to follow your video. And hopefully it's not the injector itself.
I would be willing to bet it's the connector. I would definitely replace and try it first. I replaced #7 injector and it was only the pigtail... money wasted
You make work look so easy! Wonder how much you saved doing that yourself? I like how you show from start to finish... Some people assume we all know how to get to the guts of stuff. I still think you have the most amazing toys! Great video!
Thank you, I'm thinking it's around $400. At the dealer. Thank you for your comment!
What he also saved is a a return to fix the fix. As he knows it done right...
Amen, that's why i try to do my own. I don't mind paying to get work done but you don't know who to trust and some places will do more damage than good and not loose a minute sleep over it
@@CFarmer great videos, dealership did #4 for me on my first pigtail episode, mine originally threw no codes just intermittent miss then got worse. I did my motel research nite since I never got codes you did, but dealer indicated #4 pig. 6 months, acted up last night, thinking I'll check 7 first before I condemn bad crimp job or just #4 phenomenon. Thanks for your shade tree vid's, good stuff
@@zanewatkins4008 mine didn't throw i code until it was completely bad. It took a while after intermittent miss to put code up. I hope it's something simple amd thank you for your comment. If i can be any help let me know
Great video and very step by step info. Thank you for all of the information.
Just curious, how many miles have you got on the clock? I thought I heard you say close to 300k
Thank you! 296113mi tonight. Possibly hit 300k by the the time i get home
Kinda burried the lead question, but...My 1st harness failer was #5 and the dealer convinced me I needed to do the injector. Now #4 and since it is the easier side, gonna do the harness repair by myself and see where it gets me. Put a zip tie around each harness and injector, hoping it would help.
Is there really a benefits to reinstallingbrhe foam sound deadener cover? Seems a lotneasier to make the repair without it being there. Also seems likenit wouldn't hold as much heat in that area.
Got the P0204/ P0304 codes reduced engine power yesterday 120 miles from home. AAA towed it to dealership 3 miles from my house. 5yr warranty expires in 26 days. Going to see if they will replace all 8 connectors while in there since it is a known problem.
I hope so. Glad you were still under warranty
I didn't remove the inner fender. Just went in from the top.
What year/model/trim. I want to order the replacement injector 4 pigtail because mine is coding Po204 and po304 but not sure which oem part number pigtail id need for my 2018 6.6 duramax. Any help with my issue would greatly be appreciated! Thanks in advance
Did mine like 3 weeks ago
i did my first injector last week(not my truck), was hoping it was a connector but it had a injector timing code set. #3 injector and connector fixed it up
Awesome videos ! Fixed mine in Kansas drive home to Cali like a champ
I’m just getting code P026D. U ever get this one . I put a new Map sensor in change the air filter change the fuel filter. Is there a drive cycle to reset?
What a good video do you know where I can get that scanner
Thank you! I got mine from Amazon. Here is a link to the one i have. amzn.to/3RXMBY6
I have tried it on a 2022 ram and it needed a seprate cable but it works really good on my 2018
Is that the only way you can remove the fuel lines or is there another way o different common tool?
As far as i know that's the only way
Which one it’s the injector number 4 do you have any idea ?
It's the one i was working on in this video. Drivers side second back from the front. Drivers side front to rear will be 2,4,6,8. Passenger side front to rear will be 1,3,5,7
Farmer ples how did u see the codes on the radio screen
Have you ever taken a closer look at one of the bad ends to see what is actually happening? It just seems like such a simple connector. I wonder if just reseating after a cleaning with an electrical connector cleaner or wd40 would work. Haven't had to replace any of mine yet so I'm not really sure of what I'm dealing with. Just a thought. BTW, great video's sir.
Thank you! I'm not sure what's happening with them. I have a friend who says he thinks a the injector gets older it creates resistance that gets the connector really hot and caused it to loose connection. I'm not really sure what to think except gm should help out because it out being such a common issue
@@CFarmer Have you considered trying the gold plated connectors or heard from anybody that has? I want to get a few spares and wondered if it was worth the extra money. I'll have this truck for a long time (I hope)
I didn't know that was an option. i have been getting the OEM GM connectors but if I could find them I would give them a try. If you run across them leave me a link here if you would
@@CFarmer have you found anything out with the gold plated one? Having this issue with mine
I haven't, i have a link to them on ebay but never tried them.

Awsome vid brother about to try this today if I can find the part. How much was that scanner? I need one but I can only afford a cheaper one for now.
I'm Rogelio btw
The connector at the dealer was around $120. I ordered the one i put on in this video on Amazon for around $70. The scanner was a little under $600.i left links to both in description also if you change connector i think codes will clear itself after the truck sees the issue is fixed
I hope that gets you going, if i can help let me know.
Hey great video we’re about to replace the pig tail wondering how to release the fuel pressure on the lines if need be? The Truck towed the code we took it into the dealer they said it’s a possible injector and wants 1800 dollars to do it not happening
There wasn't any pressure on mine.i had picked up a cheap tool and the lines were a pain to get apart but that was the worst of it.
@@CFarmer Perfect thanks again we were just heading back to Indiana we it all let go have you heard or know about gold connectors for these pig tails ?
I've heard of them for the older duramax but not for the l5P. Good luck with it. Let me know if that fixes you up. Was code P0204
How long of a job start to finish? About to try this on cylinder 4 as well
It took me longer because i had never done it before and was videoing it. It took me 2hrs.i think of i had to do it again after thinking on it...i doubt i would pull fender out or jack it up. I think you can get to both 10mm bolts from top after taking pipe loose from turbo. I think i could do it again in less than an hour. The passenger side #7 inner fender had to come out. I assumed it would on this one too. I was intimidated but it was an easy job. Let me know how it goes or if i can be any help let me know.
@@CFarmer thanks, I just don't have the 2 weeks to wait for the dealer to cover it on warranty. I just hit 94k miles. Washed my truck and wheel wells and now have the p0204 code. I think I will just change the connection after watching your videos
Good luck with it,i think you'll be glad you got it out of the way and saved at least $250.
Just an update. Replaced to connector and problem has went away. $120 for the part and took me 1.5 hours to replace. Thanks again for your video. It was went exactly how you described. Decided to not take the wheel well out and was able to reach everything on top just fine.
Awesome, thank you for the feedback.i have ordered 2 more connectors off Amazon. Almost half the price and this ones doing great. Glad you got it fixed up
I am in the market for a 3/4 diesel. If I get the duramax it will be a 2019 bc I hear nothing but issues with the 2020+ year models. The 2020+ powerstrokes are a beast. Hard decision. But I keep reading and seeing videos of all the injector and glow plug issues with the duramax. 🤔
I'm almost at 400k and the injector connectors have been the most aggrivating issue. Still on original injectors and emissions. Did replace both nox sensors and pinion bearings around 350k miles but that's just my experience. I know guys who've had better luck and worse.
@@CFarmer yeah this will be my first diesel truck. I am a apprentice lineman for a utility company and I want a bigger camper, so I have to get a bigger truck. I currently own a 2021 lariat f150 fx4. Just want to get a good diesel truck that’s going to last and not leave me stranded all the time. So if all that started happening 300k miles I think the duramax might be the one. It’s hard to find a 2020+ powerstroke that’s not over priced. I found a 2019 gmc Denali 4x4 with 45k miles for 61k
That's sounds like a decent price on today's market. The first injector connector was around 210k. I didn't have any issues up till that point
@@CFarmer thank you so much for feed back bro. Stay safe on the roads.
Yes sir, sorry it took so long
Dealer is telling me I should replace my injectors when replacing a connector. What do you guys think ? They did say that the injector creates resistance so that’s why the connectors go bad. But should I replace injectors ? 4k Job. Thanks for your opinions
I've done 3 connectors now. No injectors on mine, 332k miles. Never replaced connector twice on mine
Thank you! Great video. I’m at 100k miles this is my second one according to dealer
Hey C
Good job bud keep it up the thing is shit no room there bro that’s anoth reason I stick with the 6 in line all day (Jesus … )
Hey men one question where did you get the stand ? That’s sick
Thank you! The tire step, i ordered it off Amazon. Don't use it as often as i thought i would but it's awesome when i need it. I put a link in the description to the one i have
@@CFarmer thanks men
What's your thoughts on P0216 2021 L5P? 168k
I haven't had to deal with p0216 myself but from what I'm reading it could be quite a few things from a dirty fuel filter to a dirty map sensor. Without seeing it in not sure where is start to look. Wish i could be more help
@@CFarmer no worries. Thanks
I currently have my GMC Duramax lp5 at Carl Black dealership in Orlando Florida right service advisor explain to me that GM knows they have faulty parts and acknowledges the issue and has a new part in part number but I still have to pay for the repair I just ran out of warranty 2000 miles so a Duramax diesel with 170,000 mi on it with this and I believe he said the repair was anywhere from$2,000 to $2,500.00 this shows the greed of GM if you know you have a bad part then do the right thing and recall it and fix it for free why should the cost of repair for bad part fall on the consumer. We need a class action lawsuit against GM for this issue
Man you been in AZ a lot lately!!! We need to connect sometime brother!
That'd be awesome, I've been running 40 to California pretty regular but on 80 headed to Northern Cali this week

I bought a 2020 GMC Denali HD and at 60k miles now nothing but problems. Is 1st exhaust heater... Then injector, 4 days later injector harness... $1900 for the harness and weeks to be delivered they say.... The exhaust heater took 6 weeks to be delivered.as a small contractor this truck is causing me to lose so many jobs.. The radio or GPS unit stopped working, the electric all went completely dead in the truck completely draining both batteries. The truck was overheating before. I mean non stop problems since day one.. GM has tried to help a little i guess but I need a buy back, two years of stress and problems is what they sold me.. I've had all of the Duramax trucks but this L5P is something to stay away from.
I feel like I've had pretty good luck out of mine but I've heard of others with horror stories and others with over 500k on them. A few months ago someone sent me the link to the wiring harness. It was 2 pieces, one for each side on GM Parts warehouse.com. was around $250. Each. I'll try to send the link if i can find it but i have to wonder if dealer isn't taking advantage.i know a guy who just spent over $6500. At dealer getting new injectors and all connectors and was still having same issue. Took to a reputable diesel shop and they swear it's in the transmission. Here is a complete wiring harness for the l5P . There are 2 different harnesses listed but both same price

Just Broke down with code P0204 in Morrilton,Ar. Second time in less than 3 months that I get this code, first time I paid $600 to get injector replaced now I get to this on my own. Hopefully it is just the pigtail. How did you know it would be the pigtail though?
It's always been the pigtail for me. I've replaced #7,4,5 then PO207 came up again and i replaced injector. That didn't fix the issue so i put a 2nd #7 pigtail on and no issues since (injector #7 wasent bad pigtail fixed it)
