LT10s no trailing spar. bad ecu?

Im getting no spark from the trailing coil. The tach hasn't worked for awhile either.
I've got a Microtech ecu.
I've done a bit of research and checked voltage of the ignition output lead from the ecu while cranking the engine by hand. I get 0 voltage.

Is there something else I should be checking or do I need to be looking for another ecu?

It needs to be checked with a scope. The system fires the coil by pulling the output low, not high. A scope will allow you to see the square wave.
