    17 Yukon XL 6.2 stalling, hard to start, injector issue

    So short update. Got the Yukon home over a period of a couple days and started breaking it down. Intake is still as nasty as the previous photo I posted, but I haven’t taken any steps to clean it yet, so that’s understandable. Got the pushrods out, and sure enough, the third one back on the...

    17 Yukon XL 6.2 stalling, hard to start, injector issue

    I’ve only checked the oil level and not oil from out of the pan to see if there’s shavings in there or not. It’s still at the dealership right now since I haven’t had the chance between work and the holiday to go over there and pay for the diagnostic and have it towed home. Possibly taking it to...

    I realized I never attached the video. Don’t mind the hazards clicking.

    17 Yukon XL 6.2 stalling, hard to start, injector issue

    So a bit of an update. After having all these issues, I gave in and took it to the dealer to have the problem diagnosed. Was able to get it started up again to drive it to the dealership, where it had this awful noise while the engine was running that I’ll attach. Dealership called today and...

    17 Yukon XL 6.2 stalling, hard to start, injector issue

    When I had the intake off to check the injector part numbers, I looked inside the intake and noticed it was excessively dirty. I bought sea foam to do a cleaning but wanted to make sure it was running well again before I introduced something else to the mix. Problem is, it was running fine...

    17 Yukon XL 6.2 stalling, hard to start, injector issue

    So little update. Two days ago while my wife was driving the “oil pressure low, stop engine now” light comes on, and after she pulls over and turns it off, it wouldn’t start up again. Had it towed home, and let it sit with the trickle charger on the battery for a few hours while I was at work...

    17 Yukon XL 6.2 stalling, hard to start, injector issue

    That would be great but unfortunately I live in SC so it doesn’t apply to me. Injectors will be here Saturday. Today it threw a new code, P0305, cylinder 5 misfire. It’s running rough while in drive and moving but runs okay in park. Can’t wait for this to be over.

    17 Yukon XL 6.2 stalling, hard to start, injector issue

    Checked all connections, and everything’s tight. P050D code came back, so I took the intake off to get to the part numbers for the injectors. It was a pain but got it, and I ordered the injectors. Curiously enough, the P050D code went away after I put everything back together. Still starts the...

    Saw this right after I posted my latest reply. I’ll do a once over with all the connections and double check before ordering stuff. Thank you for the response. Pics, as requested. Swapped the Suburban for the Yukon XL

    17 Yukon XL 6.2 stalling, hard to start, injector issue

    I appreciate it. I did see this thread, and unfortunately if the injector replacement worked for him it sounds like that’s in my future. Forgot to add I’m at 106k miles and I know the injectors are a known issue around this time. May just do plugs and wires while I’m at it for good measure.

    It’s a slow crank, like it barely wants to turn over at first, but will start up once it gets going, usually within 3 seconds.

    17 Yukon XL 6.2 stalling, hard to start, injector issue

    Bought a 2017 Yukon XL 6.2 back in May and overall haven’t had too many issues other than the motor mounts being bad and replacing those under warranty. On Thanksgiving, we drove about 250 miles to a campground without issues, but about a mile before the campground, after going over a large...
