Ok, this could be a wire issue or a sending unit issue as well. you can diagnose by doing a complete wire check from the gauge to the actual sending unit that is located inside of the fuel tank.

When inspecting the wires, you will need to look for worn or lose connections. make sure there is proper voltage running through the wires as well. you can use a multimeter for the voltage check.

If the wire check is ok and there are no lose connections, this will confirm sending unit failure and you will need to replace this device to restore proper gauge function at this time.

Please rate and god bless:)

There is only one part that makes this happen, it is the fuel gauge sending unit in the fuel tank.

Town and Country Van running out of gas and guage says half a tank what could be the problem?


If your fuel gauge is showing you in accurate readings this is normal to all vehicles that are not used to fill-up gas full regularly but sometimes the cause of the inacuracy is due to faulty float valve in the gas tank you need to replace it

Dash gas gauge stops showing proper gas level once it hits half a tank. Then gauge will fluctuate between empty (light will come on), full and anywhere in between but seems fine from full tank to half


If the trouble with the gauge started after you worked on it then you likely damaged or created a restriction to the movement of the sending unit. You will have to remove the tank and double-check your work.

My gas tank is full but the gauge say,s that its empty and then full, and then half full what is wrong with it


You need to replace the fuel gauge sending unit. This is mounted on the side of the fuel pump assembly, inside the fuel tank. You will need to remove the fuel tank for this repair.

Hi:
The fuel pumps on the Chevy blazer and their full sized trucks are prone to failing, as I had to change mine on my 1996, and yours is the same model .
Ours started off intermittently dieing, then failed all together. If you have matched up the fact that you have no fuel pressure when your blazer won't start, then the fuel pump is the most likely suspect. As you know, they are not cheap, and the fuel tank is not difficult to remove, but needs to be close to empty to make the job managable. The tank is over 3 feet long, and is better removed with 2 people if you can find help.

You weren't low on gas - your fuel tank sending unit is failing and needs replacement. It's inside the tank and usually can be replaced without replacing the fuel pump as well - don't get suckered into that.

2000 chevy blazer fuel gauge


did you recently change the fuel pump? If so you needed to change the wire harness thats attached to the fuel pump, then if not, your floater need to be replaced inside your fuel tank.
How do I know? from experience.
