Hi to all i am new this forum and i would really appreciate someone's knowledge on my issue.

Im a young guy 22 just aquired this tahoe from my dad who is never around to use it. I own a 2001 Tahoe z71 (5.3) 140,000km . Winter is setting in hear in canada my tires and ride were getting shaky i brought it in to my local indie all makes type guys to see what was up ai own a 2001 Tahoe z71 (5.3 V8) 140,000km bought it off my dad who wasn't around much to use it . Winter is setting in hear in canada my tires and ride were getting shaky i brought it in to my local indie all makes type guys to see what was up an alignment etc. Turns out i need to new rubber and i was driving on some dangerous tires so i left the car there for about 5 days while we waited for tires we ordered. I gave them the car with a little less than quarter tank i think the owner test drove it too before they looked at my tires assuming i had already checked them so now assuming they used a little gas while they had it there i guess it was low i'm not sure .I got to the shop tonight they just got my rubber on we went to start it it seems to get no fuel to it so these guys see some old remote starter that the first owner must have installed these guys assume its some gm security thing so they unplug the battery try pulling some tricks with the keys they had the doors open the whole time i think i why they kept complaining about the security flashing light which as i remembered was normal they took out the whole wiring for the remote starter and restoring my wiring back to oem state. The we try again no luck still not getting gas so hes looking at the fuel gage it sitting on no gas they tried to start the car about 7 times before this. We add gas not very much though and again no luck so one mechanic bangs on the fuel pump area with a hammer as the other turns the keys and it starts 10 secs and dies. They say its my fuel pump they were asking me if i knew about a relay or emergency fuel shutoff i am not sure looking for an answer to that. They then say they think its the fuel pump i read about having 6 gallons if its dry to start it gonna try that. I called them tonight and told them to try it well see tomorrow. Apparently there is some electronic thing on the pump that could have been disconnected or died as you can see i don't now much and i need some help not looking to replace the fuel pump for fun. What are the proper steps to diagnosing this could this be electrical? The security light stuff i dont get? anything you answer i will forward to my mechanic steps to diagnosing the fuel system or other issues etc. They are quite capable of the work. aASADn alignment etc. Turns out i need to new rubber and i was driving on some dangerous tires so i left the car there for about 5 days while we waited for tires we ordered.

No, I don't know for sure what all you wrote. It's too difficult to read it.

 

That being said....

 

Sounds like a fuel pump

 

Make sure you are getting fire at the plugs

Make sure you have enough fuel in the tank.

Make sure the fuel filter is good.

Check fuel pressure regulator

Check fuel pressure

I would ask them to do a little more diagnosing than just banging on the tank. Especially because it came in running. A simple key on with a furl guage hooked up should tell you if you have enough press to start it.

If you need a jump start at a gas station, do you curse at the people you're asking for help after they say that they don't understand what you just said?

 

I tried reading your original post, and my left eye went lazy after two lines. You want help? Put in some effort before you start pissing all over us.

Again i still cant see my typing index i am sorry. This is the only reason why my message was written this way. As i stated while i was writing. I tryed to cover the whole situation to maybe get some insight on how to deal with the mechanics. Is it because im using a fire fox i can't see my typing index Mr site admin? Also anybody know if trying to start the truck with no gas can burn out the fuel pump i think this is the case? What pump would you gents recommend? Im Stuck between Delphi at 450 and Bosch for 500 is the bosch any more reliable? I know my dad has lots of bosch stuff in his 300 CE it all seems to last forever. Any insight would be awesome thank you

before ripping into your fuel pump I would suggest to get the fuel pressure checked...

 

... if you need it, for your new fuel pump stick with either ACDelco from a dealer or the Delphi brand (same pump, just a different package)

 

.. also at the same time replace the external wiring connection (these get corroded)

.. and the in-tank filter sock

.. and if you can't remember when the inline fuel filter was replaced then buy a new one

 

for your other questions...

 

just trying to start the truck with no gas won't kill the fuel pump ... but continually running the truck with very low or next to no gas in the tank will eventually cause the fuel pump to overheat and wear prematurely

 

no, using firefox is not a problem for the site.. I do this on two different computers (home and office)

Thanks man. I grabbed a delco which is supposed to the same thing I appreciate the advice.I really like your truck i never seen someone match the air dam like that it looks proper. The damage ended up being $750 labour in included @ $69 an hour 3.5 hours they say including changing the fuel filter sounds right to you? Oh ya they are supposed to check connector too. Thanks again guys.

I'd definitely go delphi.

IN THE TEXT EDIT WINDOW THERE IS A BUTTON THAT LOOKS LIKE TWO ARROWS MAKING A CIRCLE IN THE UPPER RIGHT HAND CORNER. IF YOU CLICK THAT IT WILL TOGGLE BETWEEN RICH TEXT EDIT AND STANDARD TEXT EDIT. THIS IS YOUR FIRST ISSUE....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      2020 Trailboss 6.2 replacement

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
