Hey fellas

I have a 97 chevy suburban
I need some help with my fuel guage
What is the best way to check if the fuel guage is working?

I have pulled the sending unit, I suspect that it is bad
The levels jump all over

Is there a good way to check the gauge in the instrument cluster?

 

You need a high end scan tool capable of bidirectional controls. It will allow you to sweep the gauge on the dash.
