Have been trying to get this 84 to run.
What is the good values for the "B5" reference signal from ignition module to ECM look like using a volt meter?
I know it is to vary but what range? Low to high?
I have a constant 4.6V when turning the engine by hand. Crank sensor is good, cam sensor is ok, but will be replacing the cap.

The B5 wire continuity was checked ok.
