Looking for help/instructions on replacing fuel injector/s for a 2017 5.3L Silverado. Truck has 80K miles on it and a #5 misfire. Dealer ran a diagnostics and said the injector needs to be replaced. I found a couple pictures on the forum of the fuel injectors but very little information on steps to replace them. The only videos I could find online were for older models with a different injector diagram. Talking to the dealer they quoted me $770 to replace a single injector, gaskets and piping associated with the job. 4 hours or labor and $240 in parts. Are there any good instructions or videos out there on replacing fuel injectors on a 2017 Silverado? I've never done a job like this but consider myself mechanically include, is this an easy enough job or should I leave this to the dealer to do? I know they say if your replacing a single injector you might as well replace all 4 on one bank but is that really necessary, $110 a piece and if the other 3 are fine why replace them? The dealer said the piping and gaskets must be replaced even for a single injector replacement job. Is this all necessary? I've never had another vehicle with injector problems so this will be a first. Parts quoted- 12687650 (1) injector 12626354 (8) gaskets 12677002 (1) pipe 12677004 (1) pipe Any help, links to instruction/diagrams or videos would be awesome! I enjoy working on these projects rather than paying someone else to do the work since you learn something every time. I also want it done right. Thanks all in advance!

I'm doing my best to isolate this ticking sound that is persistent, yet intermittent. Data so far: 2018 CC SLT 1500 6.2L 4WD Max Tow 19K miles, all stock Doesn't happen when motor is cold, much more prevalent when motor is warmed Doesn't happen when letting off throttle (only under application of throttle), can be heard in neutral, park, and in drive (not in reverse enough to tell--but it happens when transmission is not engaged) Sound follows steady or increasing RPM of motor Under light to medium load, noise is prevalent, under heavy acceleration it subsides (not because of engine noise) If I turn wheels hard left, the noise disappears, straighten wheels, it returns (like wheel is blocking noise from traveling) Sound only heard on driver side If I hit some oscillating bumps on the road, it can stop for a while before returning back (under varying loads as well) If left in tow/haul mode, at 2500 rpm under light load it can still be heard Ran 2 bottles of Red Line injector cleaner and it didn't eliminate/help noise The truck was silent until the 700 mile mark and I hit an expansion joint (nothing out of the ordinary) and the sound started and has remained ever since I've checked exhaust/manifold connectors and no sign of leaks (soot) I put a hollow aluminum rod (2 foot long) to the vacuum pump and did not hear any abnormal noises directly from the pump Obviously heard injector noises when put to the injectors; haven't had chance to stop on side of road when the sound disappears to run comparison tests Sometimes it'll run dead silent when driving down the road (after complete warm up) and power delivery doesn't change but noise comes back within a minute or two Sound heard in both V-8 and V-4 modes, and while in manual shift mode Use premium 91 gas ever since purchase (93 not available in Bay Area)--use Costco Top Tier fuel (high volume station) Oil changed with Mobil 0-20W Full Synthetic every 5K miles religiously and OEM filters (indicator usually states 37% remaining at around 5k miles) 90/10 Highway/City driving Any thoughts? My MPG is seems close to normal. Lifetime average of 17, most of my time driving is short city trips or long highway driving with a bed full of gear and a dirt bike. Some of the actions seem like it could be a noise related to the vacuum pump but the pump doesn't exhibit any noises itself. Sounds kind of like exhaust leak--exhaust seems to check out (no notable soot around connections or along piping that is visible). If it was something loose, I would think that even under deceleration (letting off throttle) would cause the noise to persist. It follows increasing RPM. I've checked around the footwell and haven't noiced any plugs missing or issues there. The fact that the sound is not there when cold or after some bumpy roads makes me think something else is up. Thoughts? Things to check? When it is quiet, this truck is wonderful. The ticking in the background that comes and goes is like a form of Chinese water torture. The fact that it does go away sometimes makes me even crazier as I know it could be better. When I bought it, it did not make this noise. Only after 700 miles of driving did it begin to tick tick tick away.

Why are so many 2014-18 5.3 fuel injectors going bad? Is it due to no changeable fuel filter? Are they just clogged? How can we prevent it? Sea foam?

Here is a 2014+ GM 1500 HOW TO: Remove Fuel Injectors If you haven't already look at the HOW TO: Remove the Air box and the Intake Manifold topics Disconnect Battery terminal remove air box assembly remove intake manifold release any built up pressure by unscrewing the fuel filler cap. Remove the foam insulator pad Disconnect the Fuel injector connectors Remove mounting bolts on fuel rail. Remove fuel rail with injectors Using snap ring pliers remove the ring around the injector remove injector replace with unnecessarily high flowing injectors Have fun!! If these are helpful let me know what guides you'd like me to post. -
2016 Silverado LTZ 5.3L I had 8 injectors replaced at Chevrolet 5/13/19. Code read p050d (NoWarranty) Check engine light had come on before but it would go away. I just now took it in for injectors. Every time I’m in heavy traffic I get home and it ticks almost like a Diesel. Im saying diesel because I had a gas 2005 F150 that sounded like a diesel. There is No check engine Light on now. I know something is wrong. What could be the problem? What is it that can cause the motor to work extra hard and feel strained. I still feel a rough idle when I let go of the gas. -
I buught a 2011 silverado 1500 5.3 with 130000 mi May . The oil became deluded with gas - I changed all 8 injectors with new Delco injectors. I'm still getting gas in the oil. It runs good - fuel milage is about 14 mpg. Can there be a problem with the computer keeping the injectors open after the ignition is off? Would a diagnostic check at a GM dealer show a problem with injectors? PS the check engine light has not came on Thanks for any help Sisu01

Ok so a while back I posted about my 2500HD running rough, I changed the Injectors (2 weren’t firing) and then it ran as bad if not worse and started knocking. Well today day I finally got around to pulling the engine apart to find #3 rod broke in half and into pieces. Anyone have any ideas on what happened?
