Anyone still following this thread? I'm having a similar issue with my lights and gauges. I bridged a section of my circuit board and cleaned corrosion but that didn't seem to be the issue for the gas gauge. the rest of my dash is working a lot better but still no gas. Think it could be the float? I feel like thats a whole other can of worms.
anyone had similar issues?
