Do you have power to the large amp fuses in the engine compartment fuse box? sounds like one of the main fuses is blown

Are you getting power to the coils when the key is on? how about power to the "engine" fuse in the dash fuse box?

Customer: replied 10 months ago.
I tested the battery cables that connect to the fuse box and they tested 12.46 volts, and I checked the fuses as well and they were fine, now I don't have power at all to anything, nothing turns on, no dome lights,radio,windows,odometer is out all well, key fob does not unlock doors, or sound the alarm, I thought I was a relay as well but I did replace the main 100a fuse today and it did nothing

Hummmm. Do you know which relay is the EFI main relay? if so, do you have any power to the terminals in the fuse box when the relay is removed?
