Thank you all for your input and replies. I ended up sending the ECM to a specialist to analyze it. The ECM was actually functioning properly, other than a failing memory module (which would not effect the no-start condition). After following the advice of things to check by the ECM specialist, I discovered a failed 12V circuit breaker that supplied power to 1 of 2 legs of power to the ECM in the engine bay. After replacing it, bus fired right up.
