Pin 1 of the power stage is coming from the - (aka31) terminal of the ignition coil. Check for voltage at the + (aka15) side of the coil first. It comes directly from the ignition switch.

If the voltage is at the coil +, check for voltage at the - side. If there, you have an open wire to the power stage pin 1. Not there, disconnect all wires from - side and recheck. There; one of the wires you removed (possibly the one leading to tach) is grounded - not there; coil primary is open.
