Can you turn the crank by hand, either at the crank shaft pulley or flywheel? If not the engine is froze up. If the engine is froze up, chasing wiring circuits won't help.
You can check the fuses in the wiring diagram for voltage. You can check voltage circuits at starter, any testing, make sure tranny is in park or neutral and the parking brake is set. Any applicable trouble codes/ security system? What about the neutral switch/transmission range sensor?
Unless you can personally do some testing on the wiring circuits, I dont know what else to tell you.
