Yeah, don't buy one.  Get a scan tool with bi-directional communications that was made for your truck.  GMs MDI2 with GDS software and a laptop will allow you to see all the codes and runs graphs and diagnostics and tests and resets, etc. on your truck.

 

Thanks.  I will check it out.

Update from my last post on May 14th.  Dealer originally said my 5 year power train warranty was covering the replacement of all 8 injectors.

 

Waited about 5 days and heard nothing back.  Called service writer and was told the injectors would not be covered.  I asked if they could check to see

if the injectors would be covered under my extended warranty - GMPP - GM Protection Plan - which expires in 2021 or 84,000 miles on odometer.

 

They checked and said GMPP is covering all 8 injectors and my deductible is $200.00.

 

Now the dealer did not clear the engine light the second time it came on.  It has remained on - until yesterday - light went off and has not come back on.

 

Waiting to see what happens.  Do these CELs normally go off after a certain amount of time?

 

Truck still runs good - only I notice a sight rough idle when starting truck cold.

 

Purchased truck new in August, 2014.  Now has 30,000 miles.

When the CEL turns off on it's own depends on the specific problem.  Some problems, like if the MAF sensor is left unplugged, will turn off right away when it's plugged in again, others will need a certain number of ignition cycles without the problem reoccurring before the light goes off, and others will require one or more testing cycles to complete before it goes off on it's own (where the testing cycle may not happen immediately or take some time to complete).

Update from my last post on May 25th.

 

My extended warranty - GMPP - GM Protection Plan - which expires in 2021 or 84,000 miles - is covering the cost of the 8 new fuel injectors less a $200.00 deductible.

 

I dropped my '14 GMC Sierra off at the dealer today at 4:30PM.  Service Rep said I should have it back Thurs. afternoon.  I was informed the 5 Year PowerTrain warranty

does not cover fuel injectors.  FYI only code P050D logged when CEL came on.  No other codes.  Will post again after I get the truck back.

Picked up my truck from the dealer today - Wed, June 12th.  All 8 fuel injectors were replaced.

 

Receipt lists  " INSTALLED 12684125  :SL-N-INJECTOR KIT (0300-CT)  Qty: 8 "

 

My "receipt" lists no numbers for labor, materials, etc. - just says Warranty under Amount.

 

I did get a look at the paper with the total on it - around $1,200.00.  Dealer service rep said something about

their cost billed back to GMPP and my cost without the extended warranty would have been much higher.

 

I paid $200.00 - my extended warranty deductible.  Time will tell if this fix works and keeps the CEL off.

I am having the same code and problems with my ‘17 Silverado with the 6.2 with 47,000 miles. Dealership said that the injectors aren’t covered under warranty even though they know they are a problem. How do I get GM to warranty these?

Unless you got the letter from gm stating they extended the warranty on the injectors on your specific VIN, plan on paying for them yourself. If you're mechanically inclined do it yourself and save a lot of money. All you need is 8 injectors, which might be hard to find with the strike, 2 high pressure fuel lines and 8 intake gaskets. There's videos on YouTube showing how it's done. It should only take 4 hours or so depending on skill level. Just make sure the holes in the head where the injectors go are clean and free of any burrs.

I replaced my bank 2 injectors last week then had 2 of them fail again this week. Second time took me less than 2 hours. Only thing I can guess is there was something in the hole that nicked the seals and caused them to fail prematurely. Either that of there's something wrong with my engine causing the seals to fail. Both times my injectors failed was on cylinders 4 and 6 which are AFM cylinders which has me thinking there's something deeper going on. I guess we'll see if I can make it more than a week this time.

with the P050D code...'16 silverado, ~65k miles, no extended warranty...the CEL has been coming on and off for quite some time...but since i checked it, it has always been the P050D code...first recommendations were to flush with injector cleaner...i have done that a few times...seemed to work eventually...but i am to the point it must be something more...would it be worth changing the spark plugs before i take it to the shop?  that is one of the recommended fixes (and would be MUCH cheaper than injectors) but i dont want to just through away $50-$100 on spark plugs if they arent needed...

 

if not, since i am out of warranty, i dont plan on going to a dealership...plan on going to a regular mechanic...any idea what the damage will be?  sounds like the $1200 mentioned above was internal charges...i'm nervous what the bill might be...

 

this has been the worst chevy (out of three, i have bought each brand new) i have every had...it is frustrating as hell...

I had that same code but a p0300 also and was started to blow white smoke out of the exhaust. I ended up just paying out of pocket for injectors and fuel lines. It wasn’t worth the fight with GM. My mechanics checked everything else out also. Spark plugs were fouled and the cylinders weren’t washed out with fuel. He changed the oil though and did an upper induction cleaning   I just got the call today that it’s done, a month and a half later, about to write an $1800 check for 8 new injectors, new fuel lines, oil change, and induction cleaning. If you do just the injectors and fuel lines it should be around 1,200-1,400

What part numbers are you guys getting for the injectors? The ones that came out of my truck are 12668390, dealership said new replacement part was 12684125, but then looks like 12698484 is the newest part. I ordered 12698484 from GM wholesale dealer, box says 12698484 but the injector is stamped 12681212.

 

Seems like a lot of conflicting info on this fuel injector issue..

 

12681212 (that I just got in today) is grouped with 12668390 (that came out of my truck) under the latest replacement number so I'm guessing I can use these. Everywhere is back ordered so I guess I'm lucky I even got these

      cam upgrade in CA

      By AidenVorpagel · Posted

      hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you

      Possible lifter tick after DOD delete

      By B14Sierra · Posted

      Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      So, do I go elbow-deep on this thing or list it for sale and play dumb? Seems to "runs good."   I'm about $1200 away from having: -a rebuilt injector ($300) -a new cat ($250) -a new cat back exhaust (OE style) ($300) -a new AC compressor ($200) -AC refrigerant charge ($150)   In theory, this should rectify the obvious detracting issues from its value and operability. Cold AC with a non-squeaking AC pulley both sounds and feels good. An exhaust that isn't cut/hacked in 17 different places and doesn't vibrate on a crossmember would make it sound and feel less janky. A working cat would help the stink, and will save the earth, but *if and only if* the fuel system is working properly, which would also address the intermittent "rich" CEL.   Heard a good one... CEL for "Rich condition" means you haven't spent enough money on the truck lately, and it's letting you know.   Rebuilding the injector would seem to be the most important part. Replacing the cat would be secondary. I don't think mine is plugged or overly restricted, but it might be a little restricted? I have no good way to tell other than seat of the pants feel. I hate the smell.   The current theory is I have a rich idle problem: A bad fuel pressure regulator, or a leaking injector(s) being the highest probabilities. I already replaced the FPR but that doesn't mean its replacement isn't also bad. It was a new part from Dorman, but the packaging looked like it had been sitting on a shelf for 20 years.   This is the (single) upstream O2 sensor shown at idle. I'm getting a lot of "rich" it seems. Sometimes it stays high like that and doesn't drop down. That makes me think it's processing injector leaks or a partially stuck open injector.     Other times it looks like this. Nice oscillations between rich and lean, which is what I think it should be. Under load and at speed, the oscillations are nice and tight and uniform looking, high and low.     Fuel trims suggest the PCM is compensating pretty hard at idle to pull fuel out. But it's not enough to trip a CEL. Something about slowing to a stop: brake vaccum booster, EGR, or the EVAP purge is delayed, or there's pooled fuel in the intake again that's draining into a cylinder is enough to set the CEL. Of course, in two days of driving, it hasn't set. I was hoping to actually look at the freeze-frame data when it sets. IAT is high because it's idling on an 83 degree day here.
