2017 Silverado - Fuel Injector Replacement Help

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!

If you pull one bank of injectors and replace one, the other 3 need the lower seals replaced. Requires special tools to install and size the new seals.

I'm looking online now at parts, I just found all the parts I listed above to half the price the dealer quoted me.

 

Would the replacements for the lower seals be included in the "seal kit" part # 12672366 ?

 

Are the special tools something only the dealer would have? 

 

Why replace (8) intake manifold gaskets as the dealer has parts on the quote?  12626354           (8) gaskets 

 

It seems to me someone out there would have put together some step by step or video of replacing these since I've read several forums with guys having bad injectors on these new trucks.

I can't seem to locate the injector r&r in my alldata mobile app. I'll check on the pc once I'm home.

Man, on a 2017 you need new injector already?

You should contact GM and complain.

 

My 2011 BMW x5 needs #6. Dealer quoted $1400.

Getting it done elsewhere for $700. Hope its not that expensive for you.

I've received two different quotes now from dealers for $770 to replace a single injector. Even though only the #5 injector is misfiring and bad they are recommending replacing all 4 on the side. To replace 4 it would be around $1200

 

I can buy all the new parts for around $150.  I was hoping to attempt the work myself and figured even if it took me a day to do the work at least I learned something and can do it again next time. Reading more and more forums it sounds like this can be a common problem and I don't plan on paying $770 each time I need an injector replaced.

I'm not finding any info on injector/ orings when i search through alldata on the pc. I spoke with a rep last week and he said they have the ability to add info. I'll see if they can add that r&r along with the emissions.

If you look up super charger instruction manuals, they give you step by step instructions with color photos for removing the intake.

I ran into the issue of not knowing and took mine to the stealership and paid $1000 for one injector and a ignition coil.  Never again.  I had searched for days to figure out the issue and finally came upon this video where he did this on a suburban or a tahoe but it is the same process for a silverado.  Looks time consuming but the parts are less expensive.  Roughly under $400 if you do all the parts.

      Aftermath of Repair of Leaking Brake Line

      By unit731 · Posted

      Thanks for response. Leak was right under drivers seat or thereabout.   Had checked by other mechanics and have read other information.   The solution can be a tad complicated and replacing multiple parts And with some.  The issue was still the same.   The brakes do work.   Just that the pedal is softer and goes further down.  But the brakes do work.

      Breaking News!    I'm going to tell you that I'm going to tell you.  Then I'm going to tell you what I'm going to tell you.  Then I'm going to tell you.  Then I'm going to tell you what I told  you.  Then I'm going to tell you what I'm about to tell you on the other side of the break.  Then we're going to break. Then I'm not going to tell you what I told you I was going to tell you.  But I'll tell you something else that is Breaking News just coming to the desk that everyone reported on yesterday.  Then I'll tease a human interest telling I'll get to on the other side of a larger break. Then I'll tell you one item in 20 seconds and go back to an even longer break. Longest break of the night.  Then I'll tell you a fluff piece that takes 10 seconds and sign off into a three minute break while you wait for the next 30 minutes of rinse and repeat on the local news.    In al you'll get about 12 minutes of something, 5 minutes of which is worth hearing in a 30 minute show and 18 minutes of advertising at a sound level twice as loud as the news.    Of course you can switch to cable news and hear 12 different people tell the same four stories in much the same format as the Network News for 20 hours of which the majority will be advertising.  And four hours of late night Specials about things you wonder why you stayed up to listen to. Half of which will be repeats.....   OR you can go for a drive

      Audio Dampening and quiet

      By Afennell19 · Posted

      Did you ever figure this out? My 2022 Trail Boss, and now my 2026 LT did this from time to time.  I believe it was more connected to Android Auto and my phone being the cause. Maybe try going for a drive, sans cell phone.... and see if it happens?

      2026 Sierra 1500 Denali - Sound upgrade?

      By Afennell19 · Posted

      I have a 2026 Silverado LT, the non bose as well.  Upgrading the door speakers is pretty straightforward. You could honestly go to walmart, or Auto Zone/ O Reilly and get a set of 6x9s for the front, and 6.5s for the rear. You do also have to get some adapters for each, but they are like $10 a pair on Amazon. Then some plug and play harnesses that are about $10 a pair on Amazon as well.  And I would also suggest a 10 pack of the Amazon Basics sound deadening. Slap that all around the speakers and on the open metal of the inside of the door. And your golden.   I am currently doing this with my Silverado. Although I am having a bit of trouble because I am snooby I guess and bought some Alpine S2 S69c's which are 2 way components and I am having to wire from the door up to the dash....  Having never installed speakers before, its taking me just a bit to get everything correct. But if you dont buy expensive component speakers, and just some $40-$50 door speakers. You will DRASTICALLY improve the sound over these stock paper cone junk speakers. I thought my Silverado had an issue with the radio/ sound for a while.  Come to find out.  The stock speakers are just THAT SH*TTY   I cannot wait to have some decent sound in the truck   What did you end up doing?

      Parking Brake - Automatic Engagement Questions

      By newdude · Posted

      Its all automatic based on yaw sensor data.  If enough incline is detected, it engages.   My recommendation though would be to disengage it before driving off and not let it auto disengage by touching the gas pedal.  The HD trucks use the same setup as prior years, the drum in hat park brake.  But now with an electric actuator.  If you drive off repeatedly over time, it can torque the park brake shoes and can also prematurely wear them out.           Electric console shift will set the park brake on flat ground too.  Pretty sure they've got it programmed to activate every time.
