1999 ford expedition theft light blinking error 23 won't start. New ke

1999 ford expedition theft light blinking error 23 won't start. New keys made and programmed still not working. I tried every short cut listed on the web. Still no start. I replaced the ECM board, reset all the boards with unconnected ground to positive on battery. Still no start. I have an aftermarket fab been working no problems. It locks and unlocks the doors. Please, I need my suv running.

Has it been connected to a reader and shown any error codes? Guy on YouTube had the same issue and after clearing all the error codes the truck started.
