Update to my situation. I had a friend turn the key and watch the computer and voltmeter. When the key is initially turned the whole computer turns on for about 1/2 sec (visually recognized by the LED fans), then shuts back down and the little RED LED stays on and is solid (no blinking). I'm assuming that ACC goes high and then and the computer powers up and waits for the start pulse. I am thinking that either the default 1 sec TURNONDELAY (100 x 10ms = 1000ms = 1sec) is too short for the mobo to initalize (whatever it does) then wait for the start signal or the default 1 sec PULSEWIDTH is to long and confuses the mobo. Can anyone confirm this? If this is the case I am hoping these parameters are programmable.
