00 Tahoe Fuel Pump

[robj]

AARGH! (correction its an 03)

Again my 03 tahoe lt decides it doesnt want to start... or i should say it starts and then dies...


I'm pretty sure its my fuel gauge ... shows 1/2 tank doesnt seem to be stuck... or anything... but when i turn the key the fuel pump i can hear sounds like its sucking air....

has anyone had this problem before or is this a known issue or somthing?

I know there was a bullitin about tahoes instrument cluster being faulty.. like speedo and rpm... but what about fuel gauge?


Any suggestions? I hate having a gas tank strapped in the trunk...(it USED to work fine fuel light and all)

thanks!

Did you get this fixed? If so, what was it?

 

[robj]

well i am currently fighting with chevy about it. I took the car in under the warrenty letter and they told me its the fuel sending unit. I doubt it because a scan with the tech 2 (at my mechanics shop) showed that the sending unit was showing 94 % but the gauge cluster was showing over full !

Also the way Chevy diagnosed it was by a sweep scan for the problem which upon some reading says that for this issue you CANNOT use a sweep scan. the results are inconclusive.

So im going to put in the sending unit.. and if that doesnt fix the problem *i wont hold my breathe* then chevy will be covering the cost of that unit as well as replacing my gauge cluster... other then that i love my hoe.. just having a 5 gallon walmart gascan in the back that has proven itself to leak all over me kinda of ruins my day !

i had happen actually last week mine ran out of gas and the light hadnt come on yet. all the times before the light wouldbe on? idk it was akward.

 

[robj]

yah did you get one of the letters in the amil and do you have below 70k on the car? i wonder if its the same thing!

I'm going to put in my fuel sending unit tomorrow and see what happens if the issue continues or not

Sending unit

When I got my "00" Yuk a few weeks ago the gas gauge did not work. They said this was a common problem with these vehicles. They fixed it and everything seems fine now.

 

[robj]

do you know what exaclty they fixed? I replaced the fuel pump ..i pulled the tank and there was still a few gallons of gas in it...and it would run if i added 1/2 gallon it woudlnt shut off ... but if i left it for a few hours turned off it woudlnt start back up


we will see it that helped.. so far when i put the new pump in it is showing the right level (i think so far heh)

The gas guage sending unit on my '00 Tahoe 5.3 went bad at 63K miles in 2005. My fuel pump whines when at just under 1/4 tank reading. It has done that for about 5 years now, but the dealer keeps telling me that this is "normal". Of course it is more like BS, but you know the story.

As stated above, I believe this is fairly common to these years of trucks.

Just read that GM has come out with a new gas "additive" on one of the sites. Have not tried it yet in my truck, but I am planning to do so to see if it helps the whining situation.

Saved it, and am pasting below.

Hope this helps.

Added Benefits and Uses
The PLUS portion of GM Fuel System Treatment PLUS is the addition of a filmer additive that, when used regularly, can protect fuel system sending units from the corrosive effects of certain sulfur contaminants found in some of today's gasoline.

One bottle of GM Fuel System Treatment PLUS added to the fuel tank at each oil change:

� Cleans -- Sulfur corrosion from fuel gauge sending units.

Just put a fuel pump module in my 03 Tahoe as well. Did everything said above. Would crank and then sputter and cut off. Also, gas hand would go all over. Since the fuel pump module has the send unit and the fuel pump, the module fixed both problems. Thing that gets me is that I went ahead and replaced the fuel filter while it was apart, and it was pretty bad. Problem is, I just replaced it less than 10k miles ago. I don't live in a harsh, dirty environment, so what gives? If the fuel filter is getting that clogged that early, its putting a lot more strain on my fuel pump. I definitely don't want to keep replacing that fuel pump!

yah thats terrible if its a fuel filter like the in tank ones that go right over where the hoses go... that is probably the fuel your getting is crappy.. or had some garbage in it.... i would prolly drop the tank clean it out completely.. and hten not go to that gas station again ... my filter was 100 % clean


so far it says im down to 1/4 tank ... if i have the issue again tomorrow when i go start my car ill be angry... but SO FAR so good * crosses fingers*
