Question about 2006 Chevrolet Trailblazer
Khooper, in another forum, told me that "Chevron Techron Fuel System Treatment Plus can remove harmful sulfur deposits from the sending unit and a filmer agent that can prevent the deposition of said sulfur"
My 05 Trailblazer LT 2WD.
Erratic readings, and when the fuel level was below 1/2 full, the needle would sit on "Empty" with the amber light staying on.
So I went to a dealer, they replaced the fuel level sensor (p/n 19177712 SEN KIT 3.107 $118.62) with labor $270.00 for a total of $398.86 this appears to have fixed it for now.
I also talked to another mechanic who blames ethanol for these deposits !

Sound like your fuel sending unit has gone bad. There is a sensor attached to the float on the sending unit that reads the floats position relative to the fuel in the tank,these sensors wear out over time and the float will stop reading the proper level. Unfortunately, most fuel senders that are in the fuel tank also come equipped with a new fuel pump on them, therefore making them a higher price. But you are definately going to have to have that replaced unless you feel safe relying on your trip meter. Hope this helps.
