Let review for the LURKERS.
The most important signal is the reference position signal.
It signals the ECU to create the spark and to pump the fuel.
My WAG was "most likely the signal from the reference sensor is missing"
Electronic ignitions can be very troublesome, since there is no visual, just a input and waiting for the output.
Now a points and condenser distributor that is a real deal tool.
Just BSing, but it is amazing sometimes when you can hear it start up.
