I own a 2000 s10 blazer and my gas gauge isnt working at all. When I first bought vehicle, it would trip out until i put it into gear. Then go to its destination. Then I checked coolant guage connector the other day and now it doesnt work at all. Tried a new cluster guage. Nothing. Any helpful tips?

 

I too own a 2000 Blazer. I'm having the same problem with my fuel gauge. It only works from F to 3/4 of a tank then stops. However, when it gets below the 3/4 mark (guessing by miles at that point) and I put it in park, it starts wigging out. I think it may have to be a problem with the sensor (or floater) in the tank. I think it may need to be replaced. That is going to be my next move I think. As for the coolant gauge, I really don't know what's wrong there.

 

Its the fuel level sending unit. Its easiest just to replace the pump and sending unit at the same time. Stick with delphi or delco or you will be doing it again soon lol.
