So my fuel gauge reads 3/4 tank after every time I fill up... not a big deal to me. But I put my truck in for the gauges to be replaced under the GM warranty and asked them to check out the issues with the gas gauge.
Here is what I was told:
"The fuel level sensor is going bad, and when it finally shorts out, it is going to take out the fuel module and fuel pump with it, another $680 to repair."

Is there any truth to this? ...because I don't really care if my gas gauge is exact since I rely only my trip meter, but if it is going to mess things up later, I guess I have to replace it.

 

it will happen but you can get the pump with sensor and all for about $160 or so. it happens to many trucks and its an upgraded pump and you have to splice like 2 wires and your good to go.

 

it will not do that... and as a matter of fact theyre completely full of

ive worked for gm for many years....

it is a COMMON gm problem with their sending units....

the fuel level sensor on some models can be replaces independently....

give me your vin number and ill see if i can still get the sender seperate....


but no... evel if your level sensor reads incorrectly stops responding it will not take out your module....


as a matter of fact go back to the dealer and ask them "what" part of the sender is "shorting out" since they dont short out.... the little slide taht reads the resistamce just wears out

 

So if I just leave it alone, it won't cause other problems in the future? That's a relief, I would rather spend the money on headers or something fun like that.

Since you have experience with GM... my power seat module went out on my 03 Tahoe. How hard are they to replace if I just buy the part from the dealer? Anyone have any diagrams or pictures? It is my understanding (again, according to the dealership) that they are very specialized depending on each vehicle, so are there any other (cheaper) places to buy them? Thanks

 

they ae not very "speialized" liek i said... gimme your vin ill see if i can get you a p/n and get the info you need


also im not saying your fuel pump module wont fail is they do often....

but the gauge probllem wont cause it.... running your tank below 1/4 will though

 

Good to know. I'll get my VIN for you when I get home tonight. Thanks for the help!

 

PM sent. Thanks!

 

no prob ill check tomr

 

LMFAO. Mine's been out for a good 3 years with no ill effects. I bought a replacement fuel level sensor on ebay for $25 but haven't had it installed yet.

 

How hard would the sensor be to replace in a tahoe? I assume I have to drop the tank down since I have no bed to lift off to access it.
