I have an 2018 gmc L5P. Same issues frequently. You have been a big help. I like your detailed videos. I need to replace 7 now. I have ordered the part.
Like all the other comments, I appreciate you taking the time to make these videos. I have the same truck, (less than 60,000 miles) but I see your adventures as what I can expect. Thanks again
Thank you, that's what i hope to share. Good and the bad. Despite the issue with these connectors i still love my truck. Wish i could afore to buy another identical to it . Thank you for your comment!
I really appreciate you taking the time to make these videos. Super helpful for me and saves me and everyone else hundreds of $$$
Thank you, I'm glad the videos help
I think you did a good job showing us what went on. Thanks for the information, it reinforces what I can do. 👍
Thank you
Another great Video ! You make these repairs look easy. Thanks for sharing . I have a 17 with 125K so I am grabbing some connectors. Thanks for the heads up.
Thank you! I think keeping at least one on hand is a good idea
You did a great job explaining despite the heat ! 👍🏻
I'm getting old and out of shape, lol... heat kicks my butt nowadays
424,000 miles!
Roll on driver.
Thanks for videos
Thank you!
Good refresher- caught your other vids on #4 & #1. Did this same repair on my #4 when it went out earlier this year. Only difference is I'm a firm believer in soldering all connections where possible, so that and shrink tube made for a robust connection IMO. I'm thinking of doing a wholesale connector replacement on the rest as I'm getting a generic P026D error and I've covered just about all of the other component replacements and service bulletins pertaining to it. PITA, especially when the sun is beating down on you!
Thank you! Yea... I'm getting old too. That doesn't help much. I would definitely prefer solder but the butt connector is usually just quicker. Hope you get rid of the P026D. I've seen it a couple of times but it usually goes away on its own before i have a chance to look into it
excellent video. Edge of my seat the whole time. Thanks for taking the trouble to shoot this one.
Thank you!
Great video as usual and you sure are good at changing those injector connectors. Frustrating situation, but you make it look easy.
Thank you!
Another great video. Keep up the good work. I always look forward to your videos. Thank you.
Thank you!
Man I hate you had that happen again. Don’t know what GMs issue is with these connectors but my buddy I run with a lot has a 2021 GMC and his #4 went bad and actually melted to the injector and he was at only 110k miles. My older LML is at almost 400k and never had to replace one yet so don’t really know what they’ve changed but apparently they still got the issue with them. I had him watch some of your earlier videos on these and he ordered a couple of the connectors just in case. Glad you got it fixed. Stay safe my friend
Dang, i haven't seen one melt to injector yet. Good to always keep a spare. Hate i missed y'all last week but we'll catch up one day. Safe travels sir
@@CFarmer will do. You got my number now. Ever have trouble out on the road give me a holler if I can help I will. The bigger of network of friends we have out on the road it’s better for all of us.
Big Mule Wipes should give you a commission. It's sitting up there so pretty!
There expensive but awesome. I keep them with me all the time
Good stuff! I’m glad I found your channel
Thank you! I'm glad you like and thank you for your comment!
Thank you!! I'm 95% sure I had number 4 go out today, waiting to get a plug in the morning Hopefully
Hopefully that'll get you fixed up
Thank you!!! It got me back up and going so I can get this trailer to San Diego
Good deal!
Good video. Getting close to 500,000.
Almost
Thanks .......great video a big help.
Thank you!
If you look up nice guy in the dictionary, there is a picture of you! Thanks for sharing the information. I looked at the Amazon link you provided and it says the pigtail will not fit my 2021 L5P. I suspect this is wrong as I don't think the 20 and 21's have a different connecter. If anyone knows for sure please let me know. Thanks again and safe travels.
Thank you sir, I've never put one on a 21 but I'll look into it when i get a chance
His is a 2018 L5P - the engine is the same as 20 and 21 but I am not sure the pigtail is the same as the truck was redesigned in 2020.
My 21 loves replacing connector #4 and yeah they’re the same injector harness through 17-current
@@devonconner100 Thanks for the information👍
Love my mule wipes, but I want to know if you have been cold, lol, I see you got the electric heating blanket 🤣 I've got to find me one to go in the big truck
Me Too, they're pretty awesome!
In your opinion, if you were to properly delete your truck, how many less issues would you have? Great videos!
If i would have deleted when i bought it.... I wouldn't have had to replace the def injector and the nox sensors. That's the only issues can think of that i can think of that would've been removed during the delete. In my opinion i would still have injector connector issues and that's the main issue i have with mine. I also believe by not deleting i have cost myself engine life in the long run. The emissions make the engine work so much harder. I have also had exceptional luck out of my dpf filter. I don't personally know anyone else that has put over 400k on a stock dpf filter. I also believe if i was deleted my transmission would have probably went out long ago the way i beat on this one
Have you ever tried the 'pick' method to "repair" the injector connector? It looks like good info to get your butt off the side of the road.
I haven't myself, I know a few people who have but they still ended up having to replace the connector eventually. As long as you can tighten up the connection it should work to at least get someone off the side of the road.
Thanks for the info !!
👍
Thanks for this good video
Great video. I have an 18 duramax as well, Ive been conflicted about doing the pcv reroute. I heard the crank case builds pressure and degrades the seals.
Enjoyed
Thank you!
Quick question, do you think the failure of these connectors is metal fatigue or do you think they’re just gummed up? I have always fixed automotive connectors with electrical spray cleaner.
I'm thinking metal fatigue, I've heard of people zip tieing the wires to one side to pull against the connector to get them by until they found a replacement connector
Oh no! Least it was driver side, be safe out there driver
Thank you!
@@CFarmer HPS 7/8 or 22mm coolant cap & 1/2 to 7/8 hose barb that pcv reroute will be a $30 job ez, both on amazon
Thank you. I wanted the wc fab intake horn with the delete but I'm not seeing them on their site anymore so i will probably order that stuff today.
Have you found a way to find the random misfire before you have to do it on the road? I have had to change #4 and #5. Would love to fix while I'm home. Obviously I could just do the other 6 but didn't want to just throw parts at it.
I haven't, i did replace #1&3 just because there hard to get to but i don't know of a way to know which ones next. Like you i don't want to replace them if they're not going bad
@CFarmer yea I have the same scanner you have and not found a way to monitor injector circuits to see if I can see an issue starting to develop.
Great videos! My 2018 3500srw has the #6 doing this now. Do you use electic connector cleaner on the female end of the injector? $126 for the connector at the stealership... today.
Thank you, i haven't been using anything but it wouldn't hurt. Yea they're pricy at the dealer. I would pickup a extra from Amazon just so you have it.
Amazon one is on the way now for backup! She runs like a champ now without a stutter or a shudder. Thanks again!
Yes sir! Glad it's happy again
Have you ever had to replace injector number 1?
I haven't. I only replaced #7 and it ended up being the connector instead of the injector
Can you de-pin the connectors instead of cutting them and recrimping them?
I haven't tried but i think that would work
Anybody else have the issue of the wiring from the factory wiring harness not being the same size as the new wires on the oem replacement pigtail?
Why can’t you just extract those wires out of the connector? Thats way you don’t need to cut any the wire off of the bad connector?
Question, I've had a studder/ etc, it's occasional, I used my autel to record a trip to work and back as it was throwing no codes. Noticed number 2 showing high misfires. Got a pigtail on the way and hoping it's the issue, cleaned maf and new map sensor, do you think I'm on the right track? Balance rates and everything else seems to check out.... 2018 as well.
Very well could be. I've had mine misfire off and on for days without setting a code then when it goes it goes all at once
@@CFarmer thanks for the reply. Love watching the videos of the life of rv transporter.... fun seeing how our rvs get to destination...
Thank you, i appriciate it let me know if the pigtail fixes your issue
Can't one just trow that plastic cover away. Or is there a purpose
I would think you could toss it. The one on passenger side front is metal and shields heat from egr so i wouldn't toss that one
Do you know if there is a specific symptoms that the truck does when ever the injector pig tail goes out? My 2018 started jerking a little on my way to work and CEL light came on along with REDUCED ENGINE POWER and Code
p0205- p0305- p02ce p02cc
I have around 200k miles it's running super rough right now.
That would be the #5 injector connector. It's second from the back on the passenger side right by #7(very back on passenger side).
@@CFarmer thank you so much for your insight on this, if it wasn't for your videos guiding me, I would've had to shell out a lot of money with a crazy lead time at the dealership. Thank you for taking your time to help out!
I'm glad to help! Thank you for your comment!
What are you using to read your DTC's on your nav display
Is there any permanent solution
Do you have the gm number for the injector itself. The link just shows the connector?
I have it in my tool box. I'll be home soon and I'll get it for you
The part# i have is 12698552
It's around 190.00 on gmpartstore.com
Here is a link to it on Amazon from GM but it's way more expensive

@@CFarmer Thanks. Changing connector this weekend
Good luck with it
Are you not tired to have to fix something every month?
For the miles i put on it is not to bad... at this point I'm just tired, lol..i usually put around 12k miles a month on truck
@@CFarmer Anyway thanks for the videos, the more problems you're having the more we learn :)
Me too, lol
I got the same issue with my 2018 Denali l5P plus traction control light came on my dash if anyone know what is that traction means ?? ????
Is the engine misfiring? Shaking? Do you have a way to read the codes?
@@CFarmer yes cylinder #5 misfire detected and P020E & P0305
@@CFarmer I just order the injector conector for #5 starting with this if not I’ll get the new injector THANK YOU FOR REPLYING YOUR VIDEOS HELP ME A LOT
I bet that will fix the issue. Let me know how it goes. #5 is one of the easier ones to get to so that's a plus. Glad the videos help.
@@CFarmer thank you!! What about traction light on? It’ll go away
Can't one just trow that plastic cover away. Or is there a purpose
