Before suspecting the ECU you should check sensors like the TW sensor and
MAP sensor - a simple check of resistance can tell if they're way off.
The main relay is easy to check - listen for the fuel pump running for
2secs when you turn on the ignition. There has to be a reason for the
battery discharging so often and could also be the final cause of your
non-start - check for shorts with the car turned off and then with the
ignition on... and of course check grounding and wire harnesses.

IIRC if you crank for 30secs you should get a check engine code. Was that
a Honda OEM alternator? There have been reports of aftermarket rebuilds
failing fairly quickly.
