Re: fuel gauge
So I shorted the wire and the qauge did move. I can't test it running since the pump and sender is a complete unit, but did get a response from the gauge. I also used a meter and tested the new sending unit and it's working fine. There is some kind of resistor in the wires at the top of the tank and when I test the positive wire beyond that I am not getting a reading. Would it be possible for this resister to be causing my whole issue of the gauge not working?
