Hello and welcome to JustAnswer!
It sounds as if the powertrain control module may be down. The PCM is the module that controls all engine functions.
What you'll need to do is see if the fuel pump runs when the key is first turned on and see if the PCM will communicate with a scan tool or code reader. If neither of these happen then the PCM is down.
If fuses are good then odds are the PCM itself is the issue, but you would need to verify it's powers and grounds are good before condemning it to ensure there isn't a wiring issue.
