How do i check if my ECU is working - light doesnt come on

Is the Check Engine MIL light supposed to come on when i turn my key (bot not starting my car)? It never comes on. Any suggestions? Thanks!

If I turn my car to "ACC", the CEL usually flashes once. This is on an OBDII 99 DX, I'm not sure if an ODBI has the same functions.

My civic is obd2 also. Is my Ecu not working? I can crank my motor and get spark... Is that possible without the ECU working?
