Question about 2002 Chevrolet TrailBlazer
The gas gage has started to spend most of its time on empty with the light on and the alarm going off every so often. It travels up to half a tank and then usually stays at 1/4 tank going up and down. How hard is it to fix this - is it a do it yourself - how much $$
I had this exact same problem on my 2004 F150 3 years ago. I searched many forums and saw several suggestions about trying a tank of Chevron with Techron gas. I filled up with Chevron, and the problem went away after about 100 miles of driving. The fuel level sensor is capacitive in nature, and apparently some crud built up on it. The Chevron additives got rid of the crud.

It sounds like you have a fuel level sensor problem. The fuel level sensor attaches to the fuel pump inside the gas tank. The tank will have to be removed for access. The fuel pump assembly comes out of the top of the tank,and the sensor can be then be replaced. Removing the fuel tank is the major expense. The sensor runs around $120.00.

Drop tank yourself after you run gas out about 3 hours to replace no big deal you can do it just be safe and go slow

The fuel sending unit on the fuel pump has malfunctioned. you can replace the sending it's cheaper and you can also replace the electric motor on the pump at the same time, plus labor. Some people are reluctant to go out and buy a completely new pump for $400 or $500 plus labor, you are being robbed.

It is likely the fuel level sensor, in its mounted to the side of the fuel pump. Mounted in the fuel tank, you have to remove the fuel tank to do this.
