the ether effectively "bypasses" the Crankshaft Position Sensor during
startup. I don't know if not seeing the sensor causes the fuel pump to
stay off but I doubt it. I bypassed (electrically) the fuel pump relay
with a wire so that the fuel pump was always on during my debug.

I'd bet that the Crankshaft Position Sensor acts as a gate to the
generation of the injector pulse train. I have an oscilloscope here
but don't have the time to test it.

glad it worked for you.
