When my injectors went out last year I got the last ones available in my area. That was around October, they were struggling to catch up then and now COVID really screwed them up.

Have you tried injectors cleaning products?

I recently got some off ebay to change them out on the wife's truck. A buddy went to the junk yard and pulled some. It was a risk but it worked out for him.

Hey Mark I just purchased a 2017 Denali Ultimate Package and two weeks later I got a check engine light come on. Local dealership said it was an injector problem so I went ahead and took it back to the dealership where I made the purchase of the vehicle. Whats confusing is that the only symptom I noticed was a rough idle on cold start I really never noticed any loss in power or misfire. Yes they also told me that there is no ETA on the injectors as well. Has anyone else had this problem and if so did exchanging the injectors fix the problem for good.

Any luck on locating injectors?  My 2015 5.3L has at least one bad injector...I plan to change all eight.  Hard to believe there are no other mfg's making these.  There should be a recall. This will be my last GM vehicle.

This listing might not contain exactly what you need, but I bought all 8 injectors from this seller last year when I swapped mine out. They know their stuff and they are brand new OEM injectors. They can confirm which set you need by your VIN. Mine have performed flawlessly in the ~30k miles since installing them. https://www.ebay.com/itm/Set-of-8-BRAND-NEW-OEM-Fuel-Injectors-GM-Trucks-5-3L-2014-17-12668390/192169388605?hash=item2cbe302a3d:g:98IAAOSw37BaV3Bf

Thanks so much! I'll be ordering these tomorrow. Question, do they come with the seals installed on the tip of the injectors?  Was it a pain to switch these out?  I watched a Youtube video and the Tech made it look pretty easy.  I've turned a few wrenches back in the day but the only worries I have is with the injectors being stuck. I would hate to have to replace the rails too. Thanks again!

I assume you mean the two teflon seals on the tip that goes into the intake...yes they were on mine when they arrived. I asked the same thing before I ordered mine and they confirmed they are new and I won't have any seal issues. I would ask the seller before you buy just to have peace of mind. The gasket on the other end of the injector is a standard rubber o-ring. Mine came with those as well, but would be super cheap to buy them if they arrived without them.

Just received 8 new injectors from the same guy! Thanks for the lead!  It's nice to that each set of injectors are flow tested and matched!  Now I have to decide if I want to tackle this myself or pay someone!  It's literrally Hot as Hell in Geaogia right now!

Happy to help. You inspired me to finally get my How-To posted on replacing fuel injectors. I couldn't find a write-up on how to do it when I replaced mine last year, so I wrote one myself. Give it a read and decide if this is something you want to tackle yourself.

Thanks for the write up!!!! It was very detailed and along with the diagrams and parts numbers, this will make the job so much easier for many people like myself!

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?
