My 1982 BJ60 wont run, the 3b starts really easy but dies right away when you switch ignition from start to run. I replaced a rotten oil pressure sending unit and tested the ignition switch. I have no guages working or lights in the gauge panel. All fuses appear ok but when I removed the fuse panel it has some corrosion. I dont think I have a fuel problem cause it starts real easy but I could be wrong about that too. Any help I would really appreciate.
