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...

If you can smell gas ONLY when the engine is running, then the gas didn't get
burned completely. It could be the combination of the computer, oxygen
sensors, and/or catalytic converter is going bad. If you could smell gas when
it's parked, you might want to take it to a mechanic to have your gas line
checked for leaks and for pressure test. Here's a website that talk a little about
gas smell www.mycarsmellsbad.com good luck.

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.

High NOX readings indicate a somewhat lean condition IE: hot exhaust. Possible causes are cracked and leaking vacuum lines or lazy oxygen sensors. If possible have a reputable garage with engine electronics scanner services check the sensor to see if its helping to create the lean condition
