that would take you to crank sensor given you have done the module....with a big assumption that the wires show continuity end to end

A lot of broken parts does not make you a racer; it makes you a slow learner.

bad thing is on the 85 the crank sensor is hard wired into the sensor. when I was running the test, the sensor was showing good IDK

looking at C4B on the 85 tree, seems like it could aim at the crank sensor as well...

earlier crank sensors had the plug molded into the bracket.  later ones had wires coming off it and then the plug
