(TC) P219A? Fuel Injector Replace 2010-2017 GM Truck with Flex Fuel 4.8L 5.3L V-8
Vložit
- čas přidán 6. 09. 2024
- Today on this episode of DIY WILLY, We are going to replace all 8 fuel injectors on our 2011 Chevy Silverado with the 5.3 Flex fuel LS v-8 engine. The check engine light came on and displayed a P219A code showing fuel imbalance on bank 1. I first changed the upstream O2 sensor on bank one and the EVAP Purge valve on the plenum but neither one had any effect on clearing the trouble code. After further diagnoses we found the problem to be a fuel injector. Since all 8 of the injectors had the same hours on them I thought it best to change all 8. This repair is time consuming and you should use quality parts that may cost more but will pay off in the long run.
Difficulty Level:
I rate this about a 6 on the difficulty level of 1 to 10 with 10 being the hardest.
So follow along as we repair or upgrade our 2011 Chevy Silverado 1500 5.3 Flex Fuel.

I gotta give you credit bro!! This is one of the best real world videos Ive ever seen!! Great job bud!!!
Hello Randy, I appreciate your comment very much. I try to do my best with the videos. Have a blessed day!! Thanks for watching!!!
I have same code and chevy dealer says #3 too rich and they need to replace all... this video helped me to have an idea on how to DIY
Hello Junior, So glad the video helped you.. Thanks for watching!!
I just did some research and found out cylinders 1,7,4, and 6 are the deactivation cylinders. Probably cylinder 7 fuel injector died out over time because of power being cut to these affected cylinders so much all the time. I need to get a afm disable device and or a tune.
Injector balance video on my scan tool coming soon. Also replacing injectors soon once they arrive from rockauto, ACDelco 💪🏻
When I took the truck into the service dept for a 2nd opinion they said the proteas #6. That falls with in what you found. Could be a problem with deactivation system. That could be causing premature wear on those injectors.
@@DIYWilly yes that’s what I highly believe brother 👍🏻
Excellent video and very well explained
Thanks for sharing your knowledge
God bless
Hello Miguel, So glad you liked the video. Good luck with your repair. Thanks for watching!!
Hey Bud, I recently got the XTool D8BT Scan Tool and I did a Injector Balance test. Number 7 cylinder sounds weak. Pretty sure that’s why P219A is popping. Will order all eight acdelco and replace
That’s good news… I think? Good that you know the problem. My bad injector was also #7. Hmmm 🤔 I’ll have to check out that scan tool and maybe add it to my tool box. Thanks for sharing I really appreciate it. Good luck with the repair! I know you’ll be rid of the pesky 219A code soon!
@@DIYWilly yes dude , so far it’s a great scan tool brother. Yes the code has been so pesky lol .
excellent tutorial. You just helped me with a same problem. thanks for sharing. Great job.
Hello William, I’m glad the video helped you. Thanks for watching!! 👍
Great video information. I wish I saw it a week ago, I changed the fuel pump in my tank and couldn't find the fuse for the pump power. So now I gotta clean my fuel injectors like you just changed yours. I'm going to remove mine and try cleaning them. I forgot to purge the line coming out of the tank before I reconnected, and a bunch of junk went up to the fuel rail. Wish me luck thanks.
Hello Benjamin, Good luck with cleaning your injectors! Hope it works out for you they’re expensive to replace. Let me know how it turns out and thanks for watching!!! 👍
@@DIYWilly Yeah man thanks. I can say without a doubt there is no fuel filter between the tank pump and the fuel rail for the injectors. Just like there was no cabin air filter until I put one in.
👍
Well, I had to pull all part the gas connections everywhere I could and put hoses on in to jugs. Then turn the key a few times and flushed out everything, “ which way but including loose”. Well lo and behold hot damn. Well just after disconnecting and re-hooking up the battery. I fired the thing up and there was no more engine light. Smooth sailing without tearing out the injectors at this time. 🤗 Yippee.
That’s good news!!! That’s a win!!
Good stuff! You probably saved enough $ to buy a decent used car by doing this repair yourself! Man I miss the days of the quadrajet carbs! At least when they started acting up you had low cost options.
Yes everything is so expensive. The local service center wanted $1800 to replace the injectors. I said “No Thank You I Know a Guy”. The parts were still big $$$ but saved a lot on installation. Just glad to have it running strong again.
he saves us money and puts a funny sarcastic twist to it i love it
This video really helped me out, got the job done in about 3 hours showing teaching my son Unfortunately #7 did not seat properly and fuel was leaking. Had issues getting my injectors lined up. Going to have to redo
I’m glad the video helped you. Nothing better than teaching your son how to work on cars. 👍 That’s how I got started many years ago. Take your time and get that pesky #7 in the hole. That was my problem cylinder too. Thank for watching!! HAPPY HOLIDAYS!!
@@DIYWilly somehow the top part of the injector in the rail got unseated even with the retaining clips in place. I didn't think that would be possible
@@cpabrego you were able to fix it right?
@@DIYWilly it got too dark and cold out yesterday didn't get to pull the rails back off. I tried to not pull the rails off and fix it but no luck
@@DIYWilly we tried again today and it was good until it wasnt. #7 started leaking after we twisted the injector to get the harness plugged in.. what a pain
I'm sure that's the best way to clean it, but won't we have to deal with an idle relearn procedure or reprogramming if we take the throttle body off like that?
No.. you can also disconnect the battery before removing it if your not sure. If you would change/replace the throttle body then yes the new one could have different parameters and might require the computer to relearn has you said. But to just remove it clean it and reinstall should be no problem. Just DO NOT try to start it with out the throttle body or any other sensor disconnected. Definitely not recommended. Great question and thank for watching!
I noticed at 40:05 you said you paid $106 for each injector! That same part # on eBay is $49 each. Where did you buy them? I have a 2012 Silverado and takes the same injector as yours
Hello Sebastian, I bought the injectors from the service department at my local dealership. Yes I spent a lot of $$$ for these parts. There are other options for the injectors. With that said I have been ripped off with the wrong parts too many times. Not saying the EBay seller you saw would rip you off but I wanted original parts due to the work it takes to install them. Same as the motor mounts I changed. I bought from the dealership. There is always options just depends on if you feel lucky I guess. Hey anyway good luck with your repair! Thanks for watching!!
Do u have to replace fuel injector fuel lines???
Hello rcervantes, No you don’t have replace the fuel lines. Unless of course they are damaged. Thanks for watching!!
Great vid Sir! 👍🏽
Hello Dom, Glad you enjoyed it! Thanks for watching!!
you da man willyTHE JAKe of all TRADES or was that JACK Jack an the BEANSTALK Mabey lol pretty clean job man he shows us all the trix
Thanks bro!!
Good job! Sounds good!
Hello Doug, Thanks for watching!!
Did P219A ever come back? I had codes for P015B and P015D, both O2 Sensor code sensor 1 on both banks. After replacing with denso sensors and driving one hundred miles I got the dreaded P219A
shooting your laser at the exhaust manifold was smart, im going to try that tomorrow as i have this code and suspect a faulty injector but the laser will make short work of the diagnosing for that i think, really appreciate it, ill follow up tomorrow and let you know the result
It worked well for me. Number 7 was colder than the rest and with no misfire codes i suspended the injectors. Haven had a problem since. Let me know what you find.. Glad you liked the video and thanks for watching!
@@DIYWilly will do buddy!
Happy Holidays!!🎄⛄️
Right! I've been fighting similar issues on a 2017. Never thought to use a thermometer to check the individual runners.
Hello Craig, Hope this video helps you!! Thanks for watching!!!
Hey willy has that 219A comeback? and have you had any issue with this since install?
Hello Fran, The 219A code has not come back. No further issues with the 219A. Thanks for watching!!
Man, this stupid code came back after six months. It stays off when my range afm disabler is plugged in. If I unplug and drive it for some time, it pops back. Thinking maybe lifter 😢
Looking at live data, doesn’t show any problems
Oh no.. After the last oil change my lifters started rattling. I added another quart of oil (totaling 7quarts) and they got quieter. Maybe it’s just my imagination.
@@DIYWilly I have been running 5 quarts of Valvoline full synthetic and 1 quart of the marvel mystery mix and it has helped but I don’t know how much help we can do at this point
@@DIYWilly i’m just trying to think what else can cause his P219A code
So many things can cause this darn code
.
P219A CHEVROLET Possible Causes
Leaking or contaminated fuel injectors
Low fuel pressure or running out of fuel
Leaking evaporative emission (EVAP) canister purge valve
Exhaust or intake air system leaks
Exhaust gas recirculation (EGR) system
Positive crankcase ventilation (PCV) system is leaking or the valve is stuck open
Ignition system
Incorrectly seated engine oil dipstick, tube or oil fill cap
Where to begin? I would look at the evap system.
Im having a rough start when cold no check engine lights,replaced fuel pump still having a rough start issue.once started runs perfect n starts fine till sits overnights. Fuel alcohol content was 74% .i use 87 or 93 octane. Any ideas???
2013 Silverado 5.3 fyi
Hello Jason, The alcohol content is too high for 87 or 93. If I remember correctly it should be below 10. I would start with resetting the alcohol content. There are programmers out there that will reset it. I have another video about that and the tool I used. Here is a link to that video and the tool I used in the description.
czcams.com/video/aWG8ILlj7kU/video.htmlsi=hKQD4kDi_x3jcewJ
Thanks for watching!!
What would make this happen all of a sudden@@DIYWilly
@@jasonpriddy7828Honestly the truck has a virtual sensor and it just sometimes gets it wrong. I’ve had mine reset twice. The first time I let the service center do it and it cost me about $300. The second time I bought the tool and did it my self. So WHEN it happens again I’ll just reset it again.
If you don't mind me asking which scanner you used?? Thanks for everything @@DIYWilly
Damn, I posted a video and thought it was fixed. After driving it shows as pending dtc. Could very well be driver side injector bank 1
I also tried a few things before narrowing it down to the injectors. Thanks for watching!!
Just watched your video. Subscribed!
@@DIYWilly it came back, I need to look at injector pulse width on a scan tool
Good luck 👍
@@DIYWilly thanks appreciate it
my God man where do you live. I cant believe all the racket between the dogs the sirens the traffic and it looks like your just as calm 😅
😂 Hello John, That’s part of living in the city here in SoCal. Gotta learn to deal with the noise. Thanks for watching!!
You got rooked on the injectors!! Ebay $30 all 8 shipped to my door. All oem reconditioned
Good job!👍 Thanks for watching!!
Hole shot you got a link on ebay were you got the injectors?
Hey i have a similir problem, but in my case i have an P0174 Fuel Trim System Lean Bank 2 anything tips in what can it be ?
Could easily still be a bad injector. I would also check for vacuum leaks anywhere air can get in the engine on bank 2 side.
Great job
Thanks Jorge!!
Tengo ese problema en mi Silverado 2012 en este momento
Hope you were able to fix the problem. This repair solved the problem with my truck. Thanks for watching.
I have a 2012 Silverado Flex Fuel 5.3 L what fuel do you recommend. I usually use 85. Thanks for the video
Hello Paul, I used e85 for yours with no problem until my injectors failed. I don’t believe the e85 was at fault. I do now only run 87 gas in mine but I may go back to e85 in the summer. I think you fine with e85. Just try to use a tank of regular gas once in awhile for its lubricating ability. Thanks for watching!
I put a can of Royal Purple max-clean because I keep getting 219A and 219B code. It actually helped and the codes didn't come back for at least 2 months. Is it safe to say that it is worth changing the injectors in your opinion?
Hello Chris, I can’t speak to your problem but sounds exactly like what happened to my truck. The code would come and go. This happened for about 2 years but finally it came on and never went away. That code 219A is a pain in the butt. There are a few things that can cause it but usually there will be another code also. Replacing the injectors solved my problem. Sounds like you maybe having the same issue. Can you check your cylinders with a laser thermometer? This may help diagnose cold cylinders. With no miss fire codes good chance it’s injectors. Good luck and thanks for watching.
I dont have a laser thermometer but I'll get one and check. Thank you for the reply.
Quick question bud, I replaced the purge valve on my truck and also a Tahoe. On the Silverado, both hoses clicked on
On the Tahoe the front hose clicked on, but the hose near the firewall by the electrical part didn’t click on. Think possibly it needs replaced. Where does the other end run to? I couldn’t see where it went. Run to the vapor canister ?
Yes the tube runs towards the back of the engine and finds it’s way back to the canister
@@DIYWilly oh okay might have to replace it on the Tahoe
@@DIYWilly it has the typical hard to put gas in it. Replaced the charcoal canister, vent valve, purge valve and still does it. Only other thing could be clogged Evap lines or fuel filler problem
Could have damaged the plastic lock on the connector.
@@DIYWilly oh it was already loose when I went to take it off lol 😆
How did you remove the fuel rails. Did you just grab them,use a puller
Hello Douglas, I did use a long flat screw driver against the valve covers to gently help release the injectors from the intake manifold. Then yes simply pull up to remove the rail. You may need to get some leverage around the back to help. Hope this answers your question? Thanks for Watching and good luck with the repair!
@@DIYWilly FOR THIS YEAR DO U HAVE TO REMOVE THE INJECTOR FUEL LINES ? I ASK BECAUSE IN MY 2017 SUBURBAN EVERYONE SAYING I HAVE TO CHANGE THEM THE FUEL LINES
@@rcervantes331 My 5.3 is a different version of LS than your newer engine. I couldn’t tell you if yours requires this change.
@@DIYWilly oh ok because In my engine I would have to remove the intake and all that off to get to the injectors and you didn’t need to do that on ur car in the video they say that once I remove the lines I have to replace them because it will leak I was just looking for second opinion etc
interesting, came across this video trying to research this code. recently been through a cold snap last week and my truck threw this code while driving on the highway. put 2 bottles of techron fuel injector cleaner and filled the tank with 11 gallons of 91 no ethanol fuel. so far have drove 60 miles without the code popping again. but still think i should look it over. but i have seen these trucks being sensitive to the alcohol content percentage the computer guesses the percentage based on ignition timing and such after fill up. they have no flex fuel sensor.
before this within the last month i have had e85 mixed in the tank at random vs regular up to 10% ethanol so could of had a error in the calculation.
how many miles are on your truck. and did it run better after replacing all the injectors?
Hello Nate, my ruck about 90k on it and I’ve been having this code come and go for a couple years now. I was using a different station for e85 when the problem started to be consistent. Before I was using propel e85 for several years without issue. So I agree that the fuel I was using could have had more alcohol then the other. But also diagnostic test should bad injectors. Nearly a full tank of e85 was removed and replaced with regular gas for now. I may go back to the other propel fuel at a later date.
Thanks for watching!!
@@DIYWilly so the fuel injectors didn't solve your CK engine light
@@johnmitchell2741 yes replacing the injectors did fix the problem. No further issues and I drive the truck every day.
What tool did you use to remove fuel line from rail ? And what is the process of disconnecting the line?
a.co/d/4HGi7Fn
Just remove the safety clip and insert the tool. The line will slip off. You can buy the same tool at any auto parts store.
Cool thought there was a special trick to slip it of like put tool in and push line towards grill lol. I seen the tool just wanted to be sure. Just ordered 8 delco injectors for my 2014 escalade. Every so often it will stall coasting down hill or when the engine is warm I have to tap the throttle to get it to crank . Thinking I have a leaky injector . Thank you
@@chrisrivers3746 Good luck with the repair. Thanks again for watching!!
Keep having this code on my truck and can’t track down what is going on. Possible injector on the passenger side.
Is 219A the only code showing? If there is multiple codes fix the others first and that will usually fix 219A. I also had a tough time trying to diagnose the problem. I finally notice #7 cylinder was colder than the rest with the laser thermometer pointed at the exhaust manifold. Since there was no misfire code the only thing left was the fuel injector. I took it to the local service center for a second opinion and they eventually came back with the same findings. I replaced all the injectors due them all having the same miles/hours on them and didn’t want to have to do it again for awhile. Hope this helps! Thanks for watching!!
@@DIYWilly only code showing for now
@@DIYWilly it clears itself and sometimes comes and goes back
@@DIYWilly my truck sounds exactly like the video comment below on the passenger side
@@TurnThemWheels My truck did the exact thing. The code would come and go honestly for a couple years but then it just stayed on. I would say you have an injector starting to fail. Have you checked you fuel pressure. Most scan tools can do that in live data setting. My truck eventually started to back fire when starting and would idle rough once started. Since I replaced the injectors it runs like a new truck no more issues. Codes gone!! BUT the factory injectors of expensive. Best though to use quality parts for this repair. There are cheaper injectors but how long will they last. The factory parts worked for 11yrs. Good luck and hope you get it fixed. I recommend you start pricing injectors..
Hello willy I have a 2012 gmc sierra 5.3 vortech and took it to get obd scanned and they said I might have a bad fuel injector what do you recommend I just get new injectors for it or change my fuel I run I tried the injector cleaner didn't seem to work I currently pump 91 or e85 when I can get it near me
Hello Xavier, What code is it giving? Are there more than one? First I wanna say my problem was noticed when I was mixing e85 with 87. The mixer had too much alcohol and I had to drain it and refill with just 87. If you have the P219A I would say yes probably need to change the injectors. If there is a second code fix that first and try it. Hope this helps! Thanks for watching!!
@@DIYWilly I actually haven't even tried pumping 87 because I thought it wouldn't like that gas on a flex fuel truck but I got code P0174 system too lean and P0171 fuel trim system lean
Those codes usually deal with MAF, Oxygen sensors or possibly a air/vacuum leak. Inspect all the hoses and intake tube. Make sure everything is connected or plugged in properly. There is a cleaner for MAF sensor but need to be careful when using it not to damage the sensor. The Oxygen sensor well those just get replaced not mush service for those.
Look for cracks or loose intake tube after the MAF sensor or at throttle body.
Replacing the injectors is not hard but expensive if not needed. You can also try a laser thermometer pointed at each exhaust outlet on the manifold and look for differences. That may help narrow down a bad injector.
@@DIYWilly okay sounds good I will do that I appreciate the help and time you took out of your day to reply
Here is a link to a great explanation and troubleshooting tips on these codes..
gotech.com/articles/trouble-codes/P0171-and-P0174-lean-codes
Hope you can figure it out! Good luck!
What tool did you use to remove the fuel line to the rail?
Hello Brian, Here is a link to the tool I used.
www.amazon.com/dp/B001DKO8JK/ref=cm_sw_r_as_gl_api_gl_i_857G665JX8RSTX80DP9M?linkCode=ml2&tag=robertwill0aa-20
Thanks for watching!!
Thank You very much! Great Video. DId you have to search for e85 orings for the injectors. I was curious if there was 2 kinds of injectors, e85 and regular. I am pretty sure they need to be viton. I was just curious what you ran into when purchasing them. @@DIYWilly
My understanding was the injectors came with the correct o-rings for E85. However I will not run E85 anymore. It caused problems.
Oh really? What other problems did it cause? I make ethanol and blend it with non-ethanol gas. Injectors have been my only issue. What else did you run into? Thank you again for helping out. love the channel!@@DIYWilly
The engine uses a virtual sensor for the E85. My truck began having problems accepting the E85 and would give a trouble code for too much alcohol content? Dah it’s E85… Anyway it would run bad while trying to compensate when it was really only regular gas. It would show 80% alcohol while regular is like 10% or maybe 15. I reset the alcohol content and cleared the code. This has happened twice on my truck first time costing me $300 and a full take of gas. The service center told me the gas mixture was wrong…? There could possibly be a firmware update for the truck but I haven’t got any information from the service center yet. So for now no more alcohol!
Did that code ever come back?
Hello Chris, No the code never came back. Thanks for watching!!
@@DIYWilly I changed out O2 sensors, now I'm getting the P219a code that comes on and goes off, like you described. Next up will be new injectors.
@@Chris_1129I hope those fix your problem. If you have a digital laser thermometer you can check the exhaust manifold for which cylinder is cold. Thanks for watching!!
@@DIYWillyReplaced all 8 injectors and the battery three weeks ago. The code has not come back, and the truck runs way better.
Hello Chris, So glad you were able to repair your engine and it’s running great. 👍 Good job! Thanks for watching!!
Hello Willy, my truck (2012 Sierra 1500, 143k miles) coughs and sputters on a cold start for 15-20 seconds. After that, engine revs up to 1300 rpm for about 1 second and then back down to around 1k and is very smooth idle. The engine has no issue with acceleration, idling, or starting once’s it’s warmed up.
I’m getting a total of 9 codes (some are duplicates). 6/9 are fuel trim system rich and 2 /9 are fuel trim system lean. The last code is MAP sensor performance. I’ve done spark plugs and wires, and throttle body cleaning and still same issue. Would you assume fuel injectors are next or possibly fuel pump? Any insights into why it only struggles on a cold start and once it is warm, runs and restarts perfectly? Thank you!
I would think it’s fuel delivery but where? What are the many codes it’s giving you?
Have you had the cats checked? Try removing the first/upstream O2 sensors and see if it runs better.
@@DIYWilly
(3) P0175
(3) P0172
(1) P0174
(1) P0171
(1) P0106
Replaced MAP sensor last night and that did not change or help anything. Planning to do a fuel pressure test tonight but I haven’t thought about testing the cats or o2 sensors. Wouldn’t the truck throw a code if the o2 sensors were having issues or is that the rich and lean codes that are coming up?
Did you have to code them
Hello Cameron, No I did not have to code them. They worked right out of the box. I did erase the code causing the check engine light to come on. Thanks for watching!!
Ok thank you for the information just says online special programming
@camerongraham4944 the only part on the engine that I believe would need programming would be the throttle body if it was replaced with a new one. The computer would need to know the throttle positioning. But the injectors or many other sensors do not need programming.
Ok thank you a lot having problems with my 2010 gmc Sierra 5.3 flex fuel po172 and 175 running rich
@camerongraham4944 P0172 and P0175 are related to bank 2 of the engine. Check for vacuum leaks, maf sensor, both oxygen sensors on passenger side of the engine.. These codes show when bank 2 oxygen sensors detect to much or not enough oxygen in the exhaust. I’ve seen similar situations coming from a leak in valve covers or cracked hoses. With the right equipment you can check fuel trims to help diagnose some problems. I also like to use a laser thermometer to see differences in cylinder temperatures helping to identify improper running cylinders.
