I have a 2000 Silverado and the gas gauge is screwed up. Most of the time is says low fuel but as soon as I shift into nuetral it pops back up to the acctual amount. I know my uncles 2001 does the same thing. Just wondering if anyone else has had/ does have this happening.

Mine moves around a little (1/16-1/8) incriments but its pretty damn close to whats in there. If it shows empty almost all the time its probably a fuel sending unit sensor.

Yup, it's the sending unit which is located in the tank on the fuel pump. Mine was terrible, but when I replaced my fuel pump and sending unit, it fixed the problem.

Company work truck is a 99, its screwed up, it either says empty or full nothing in the middle. been that way for a few years now. it stays on full for a while, every so often well driving it goes to empty. A small jerk on the wheel or touch the brakes it goes back to full. we just fill up every 200 miles.

I've been waiting on this thread. I've tried every fuel system cleaner out there and I've seen no change in my truck's ability to detect how much fuel it has.

 

Big question: When I'm not on or pressing the gas pedal, my truck shows empty and my "Low Fuel" light comes on, but as soon as I give it gas it tells me the actual amount of fuel I have. Could this be an indication that my fuel pump is going out or is this just something weird with my sensor?

My old 99 (my sister drives it now) had a great fuel gauge. It always seemed like the first "half" went faster than the second "half" but I don't blame that on the gauge. Also you could get realllllly close to E. It never ran out of fuel, but it was cutting it close at times. :)

i only voted no because of when i fill up it will move around a little, but after about 10 miles or so its fine and reads correctly from there on out untill the next fill up.

See, mine whenever I start it up it will be "empty" and have the low fuel light on after about 10 miles or so it will slowly build up and then while your driving up the road it will kick back from empty the the acctual then back to empty and so on... The only cure I found was to shift into nuetral for a second or two and it will pop right up the the acctual amount... confusing I know...

That's exactly what mine did. Like I said before, replacing the fuel pump and sending unit fixed the problem.

How much did that sending unit send you back... I don't really care... keeps from others from driving the truck but still would be nice

Not exactly sure. It was the dead of winter, so I didn't feel like dropping the tank myself, and I replaced the fuel pump and sending unit together.

At last! Thought I was the only one having problem. If I fill it up it will say full and then when I stop at a light the gauge will go to E and give me the low fuel light. Does this even though I have half a tank or even a quarter, or sometimes when I start the car it will say low on fuel than gradually go up. So how hard is it to replace the sending unit and fuel pump because I'm having intermit startup problem.

My 2002, knock on wood, has 115K on it and I have had no problems. My cousin's '99 model with 180K has had all sorts of issues. My sister-in-laws '01 model with around 65K has no problems.

Had issues shortly after I bought it (used)

 

Replaced fuel pump and sending unit (at the time, you couldn't buy the sending unit separately - not sure if that's still true).

 

Been working fine for a few years now.

 

 

I lifted the bed to get to the tank at the time. Been giving serious consideration to buying a marine hatch and cutting a hole in the bed above the fuel tank to provide access. Knowing GM, its only a matter of time before the fuel pump goes. With the hatch, I could probably buy a pump and stash it in the cab so when it dies on me, I could replace wherever it dies with a few hand tools.

I had an 01 Sierra that had a screwed up fuel guage. It went back and forth from full to empty.

I have an 08 silverado now, and the guage in that seems inconsistent. I actually ran out of gas pulling into a gas station the other day. it went from just under a quarter tank to empty in about 10 miles. sometimes i'll park it with more than a 1/4 tank, and when i start it up later it only shows an 1/8th of a tank.

      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.
