Thanks Jeff, but I do have the ECM and all the sensors of course.
Check out my photos.
The device on the distributor housing that reads shaft rotation is called the Sync Sensor, while the device on the bellhousing that reads flywheel rotation is called the Crankshaft Position Sensor (CPS). They both need to be functioning before the computer signal is sent from the ECU to the ICM.
It'd be nice if I could just open/close switches or increase impedance to make it work, but the ICM is looking for specific code from the ECU before it will pass voltage through the coil. The ECU won't send that code until it gets the right input from all the sensors, or at least enough of them to start in "open loop" mode.
Given that, any other thoughts?
Now I'm wasted and I can't find my way home.
