Definitly not racing from light to light, I'll run her at WOT once or twice a tank through 1st and 2nd gears. I used to get 300+ miles on her before the low fuel light started to come on, now I get 280 miles. Grant it I have a faulty fuel guage.

GM-Tech, does this same problem plague the diesel trucks? I'm hoping I don't have to fight it when my 06 gets here. I made to about 40,000 miles (long enough to get out of warranty) before the problems started on my 2000.

Thanks for the info I will try the fuel addative . I sure do wish GM Would fix the problem instead of Icing it over though . Everyone I know who owns a chevy truck has the faulty fuel sneding unit sensor and it is not a cheap fix . Seems to me that it should be a recall item , not knowing how much fuel you have in the tank could be a very serious hazard. Say you pull into traffic and your truck quits because it is out of gas and you didn't know it. oh well geuss you can kiss your but goodbye because you didn;t have a sensor replaced that GM should have redesigned and replaced for you but that is another topic sorry to rant

No need to apoligize, you have every right to be upset and angry at GMs stupidity,lack of quality control, and customer care. If they were smart they would be reading these message boards to find out from long term users just what kinds of problems we encounter but they have too much pride me thinks.

I tried one of those gold plated containers of juice, $18. STP sells the same stuff for $1.99. Actually, it seems to have improved the problem. I might even try one more.

Does this problem affect ALL GM cars and light trucks? I just bought a 2003 Bonneville, and if this is an issue with all GM vehicles I'll start using the fuel additive now to prevent it.

After reading the bulletin posted by GM Tech I see that it does affect my Bonneville as well.

A 26 gallon tank will take 27 gallons, without burping, I have done it twice. Now I never let it get below 1/4 tank as the low fuel signal doesn't come on until you have used up at least 25.5 gallons. That isn't much reserve when you are in the western states and towns are sometimes 50-100 miles apart.

I think GM re-labels the Chevron Techron Plus. The Techron Plus says it helps prevent sending unit and pump corrosion. The techron Plus 20 Gallon size is $12.99 at Pep Boys Auto Store. Make shure the bottle says "PLUS". they still had some of the old stuff on the shelf.

http://www.homeandawaymagazine.com/Index_gauge_deception.cfm

I run synthetic 2 stroke oil in my 4 stroke motorcycles @ 1 oz per 5 gallons. I have found that it gives the inside of the tank and the carbs a thin coat of oil so that there isn't any corrosion. With over 100,000 miles on my bike, I dont have and rust in the steel tank or white powder corrosion in the fuel bowls of the carbs. Other people in my area have corrosion in thier fuel bowls with only 10,000 miles. I thought about doing the same with my truck, but was worried that the 2 stroke oil would damage the catalytic converters, so I didn't try it. I wonder if chevron is using something similar in thier techron plus???

Chevron TECHRON Concentrate Fuel System Cleaner
TECHRONŽ Concentrate Plus Fuel System Cleaner has been reformulated to clean harmful gasoline sulfurs from fuel gauge sensors and prevent further buildup. And, as always, it's unbeatable at cleaning the entire fuel system and restoring lost power and performance due to carbon buildup.

TECHRONŽ Concentrate Plus

Cleans fuel injectors, intake valves and combustion chambers

Reduces carbon buildup and deposits that cause knock, ping and run-on.

Restores lost power and performance in one application
Use every 3,000 miles or at every oil change for maximum benefit.



I also found this coupon for "buy 1 get 1 free" for the 12 gallon size. Good till the end of this month

I tried the Techron plus, It might have cleaned the fuel system but it did nothing to correct the existing problem with the fuel guage (which was expected).
So where can you buy a fuel sensor online?
I tried all of the following:
http://www.truckpartsdiscount.com

https://www.partszoneonline.com/index.php

http://gmpartsdirect.com/

http://carpartswholesale.com/

None seem to have a listing to a fuel sensor.

I also need the park brake release cable. I can't find a listing for this anywhere either (or I dont recognise the part from the description).
Any help appreciated.

Had my sensor (sensors) replaced under warranty, and it STILL isn't right. It came on and within 8 miles I filled up, and it took a hair under 25 gallons for a 26 gallon tank. That is about .6 gallons better than before, but still not right. Guess I will continue to carry an extra 5 gallons while on trips.
Begs the question, is there a seperate sensor for low fuel light? If not, how is the signal obtained? derived from fuel level sensor? Where is the derivation done? BCM? Insturment cluster?

So if I change my Fuel pump will that on my 00 Silverado, will that correct the problem? I guess then I need to purchase some additive to help the new sending you not to corrode.

I only use Chevron gas in my truck since it was new. (maybe 3 tanks of Union 76 when there wasn't a Chevron station while on a trip). I have not had a problem with my guage. It could be the quality of the fuel. Chevron fuel already comes with techron, so you might not need to add it.

I noticed that when I am on a long trip for 200 miles and I trun off the motor, when I turn it back on, the guage reads lower. It might show 1/3 tank when I stop, but when I re-start, the low fuel light comes on and it's below 1/4. If I do city driving where I start and stop frequently, I dont notice this problem.

I just fixed mine yesterday...dropped tank, removed pump/sending unit. Removed sending unit, cleaned contacts, added a little "tension" to the contacts and "fixed" the float arm to show full when tank is full and not 8 gals short of full. After pumping in 13 gals of gas tank now reads 1/2 full and will read full when tank "IS" full, also reads 1/4 tank after pumping in 6.5 gals. Took about 2.5 hours to drop tank and "repair" the sensor and replace tank. I tried the Chevron Techron "Plus" trick and it did help but didn't fix the problem. This 2002 Silverado Z71 has had nothing but Chevron and Texaco (same fuel) since new and problem showed up with about 67K miles. All is better now so far...if not I will drop tank and replace sending unit with one from ebay for $30. I have GOOD pics of the process is anyone is interested in them PM me.

This is ridiculous. I've had problems with my fuel sensor for a few years now. I'm waiting for the day my wife call me stranded out of gas because she didnt keep up with the trip. Definitely a recall item on my 2002 Tahoe. This is the first Chevy vehicle and probably the last.

Last week I went ahead and changed out the Fuel pump...kind of an expensive ordeal (even though I did the work myself), but it definitely fixed the gauge problem.

my dads truck (2000 silverado 5.3L)does something different with the fuel guage. Maybe this problem is related, maybe not. His doesn't give false readings, it just randomly will sit the needle on empty almost like the fuel guage itself isnt getting power. If you jiggle the key in the ignition some it will eventually start to work and needle will climb. this happened last time i filled up and i was a good 30 miles down the road before the needle finally climbed up to full. it seemed to park a few times on the way up.

if these 2 issues are related in any way it could also be a faulty connection at the ignition switch. Just out of curiosity next time your truck has the fuel guage issue jiggle the key in the ignition and see if anything happens. can't hurt anything.

Will try the new additive - have an '00 LT 5.3L.

Dealer had to replace my guage - failed at 63K miles in '05.

The fuel pump does "whine" though when the tank gets to about 1/4 to 1/8 full, dealer would not replace this, said it was "normal". Have had the whine in the fuel pump since about 20K miles onward, and now am at 95K miles on truck with same one, so who knows? Maybe the additive with help with that.

Well, just my $.02.
I have tried the Techron Plus numerous since this solotion was first indicated here. The next to last time was just over a week ago, I added 2 bottles to a full tank, then, this past Wednesday, I added 2 more bottles at 1/4 tank, then filled up again. still no noticeable change in my gauge.
With 120K miles, I think I will just go ahead and replace the entire Fuel Pump/Sending Unit.
Any recommendations on the best place to get one, other than the stealership?

I'm off to RockAuto now to start my search, any advice will be appreciated!
