Check for fuses/power/ground to the engine computer (or injector drive computer) whatever the case is.
Spark, fuel pump, and starter all are independant of the fuel injection computer.
Either the computer itself has gone bad, or it is not receiving power or ground, or wiring to the injectors might be bad...

You can jump across the celonoid on the starter. If the engine turns over then your problem is either the celonoid or the starter switch.

Sounds like a RFID issue. Your key most likely has a chip inside of it. Most of the time people will have multiple keys on their key chain that can cause interference with the receiver in your steering column. Try using the one ignition key to start.
