Does the fact no coils are firing have anything to do with anything??

At this point in time I can push the start button to start a game, but the kick out solenoid won't fire.  If the trough switch stays closed (since the coil doesn't fire it out) the score motor keeps running.

But, if i open the trough switch and hit the tilt, then close the trough switch to simulate a ball drain, the ball light drops one number as if in a real game.  But before hitting the tilt switch, no playfield switches or coils respond to being closed...

Is this the/a problem or simply a symptom of a larger problem (being the score motor continually running if trough switch is closed, likely to do with an incorrect start up sequence as described previously)?

Has anyone designed an EM to DMD plug so we can run diagnostics from switches on the coin door!!
