Ive been messing with my fuel gauge only reading 3/4 when full. I tried two different sending units. 1 original and 1 new aftermarket and they both have the same readings. All of the sudden I have no power to the blue sending wire Verified by gauge reading empty now and I tested blue wire output via voltmeter located at tank.
I know a blue wire connects to the speedometer round connecting harness. Assuming that’s the sender wire that goes to the tank. Does anyone know for sure if that blue wire connects anywhere else in between tank and round gauge connector ? I think this wire had slightly too much resistance and that’s why the gauge would only read 3/4 when both sending units are at full mark. I’m not getting power to that blue wire now. I might have to run a new one up under the car. Because I don’t want to rip the carpet out again if I want my gauge to work again. Anyone ever replace that blue sending wire before ? Can you please share what to look for under dash to accomplish ? I’m thinking I can run a new wire directly to the round speedometer connector. Not sure if that will work.
