[Tech II]

Turn key to "on", don't start......you may have more than one fuse block on this vehicle(underhood, interior).....check for power to the fuses with a test light.....if you have a some with power and some without, check the output legs of your ignition switch....

Could also have a wiring problem at the underhood fuseblock.....it may have "silver" colored locking bolts on top between the fuses/relays.....make sure they are tight......
