Few thinks not adding up here
if no check engine light on, PCM (the brain )not being powered and I can not see the OBDII reader communicating with a dead brain to give you no codes
with key on you should have check engine light on
if not check fuses and ignition switch
very possible to be a wiring
and you may be in need for wiring schematic
have your man check if ignition switch working the way it suppose to be
good luck
