    I think your main problem is that you are asking us to guess what your circuit is without giving us ANY INFORMATION WHATSOEVER. I have a car that won't start, can you tell me why?

    You did check to pull down PS_ON# pin at the connector? If no effect, consider that the main power supply is defective, +5VSB is supplied by a separate switcher.
