Dead crank position sensor?
On a very hot day, I had the original crank position sensor fail (probably as it cooled down.) Stopped on pit lane for tire check and car would not refire. Cranked, but no sign of life
My understanding is the cps is the only mandatory sensor for it to run. In that case I had no error flashing either. I carry a few spares and duct a bit of air to that area to help keep the thing cool and have never had another CPS fail
Fuel pressure completely at zero will also cause this. even with slight pressure it will run at idle
good luck

Spark across the gap of a spark plug?

If the fuel injectors are truly pulsing, then the ECU is Indeed trying to start the engine. I myself would want more evidence than a sniff test. Pull one of the spark plug wires off a plug (leaving that plug installed), and connect that wire into a spare spark plug. Ground the threads of the spare spark plug against the aluminum cylinder head, and have a partner crank over the engine while you check for a healthy spark with the shop lights off. If you are seeing spark, then the ECU is satisfied with enough of the sensors to meet the starting criteria.
