i get these readings with the ignition ON:

At harness that plugs into sensor:

power- 8.9 v
ground- does show continuity
signal- 4.96 v

at the ECU:

Pin 32 (crank signal input) - 4.96 v
Pin 44 (Power output to crank) - 8.9 v


Perfect.

the problem is when i plug in the sensor to the harness, the signal output changes from 4.96 v to .08 v at the harness as well as the ECU

I have tried two sensors: the one in the car before i lost spark and a new one i purchased a few days ago.


What to do?
