I cant tell whats going on with my fuel gauge. Does the cluster send current to the sender unit or does the sender unit send current to the cluster...i put a test light on the wires that you connect to the sender unit and didnt get any fire. Do you guys have any idea on what could be the problem?

 

faulty fuel guage or short or w/e in wiring freind had his fuel gauge messed up and had to get his mpg and fuel tank capacity written down then calculated how much gas he had left. he only ran outa gas once cause so idiot didnt know math that did it for him once
