Question about 2000 Chevrolet Blazer
I have had two 2000 Chev Blazers and both of them had this problem. The gas gauge stops working. It shoots from empty to full, never 1/2, always one exteme or the other. It happens when I am driving or sitting still, it does not matter how full or empty, just kinda of randomly darts back and forth. I even had 2005 Trailblazer and it started doing this about the time I sold it.
More than likely it's the gauge it sets in a circuit board and sometimes the contacts get worn and with vibration it voltage spikes it and then it fails. very seldom is it the sending unit in the tank. please rate this...thanks

Fuel sending unit is built into the fuel pump on all s-10 series blazers and pickups. this is a known issue as stated above. the only fix is to replace the fuel pump. My guage never worked on my 2000 blazer since I bought it. finnaly the pump died. wehen I replaced it I noticed the armature for the fuel sending unit was loose to the point the sensor wasnt makeing contact with the potentiometer. after replacing the pump, everythings worked 4.0.

You do not have to replace the complete sending unit/fuel pump module. You can purchase just the fuel level sensor but you are still going to have to remove the fuel module to replace it and most garages will tell you it is best to replace the complete assembly.
