still no start..

and no DTC!!!
disconnecting battery doesnt work.. reprogramming key doesnt work..
When I put key in 'on', there's a sounds under the dash of a small but loud fan running. I presume it's the alarm that lost its voice (I never acutally heard it scream. ever.. so..)
please suggest more ideas?
The no DTC (as read with a cheap OBDII reader) is the most troubling.. I thought SKREEM and PCM and almost everything else would leave a code as they die).. So nothing thinks it's failed, yet..
