The computer (brain of the car), likely knows if the car has failed fuel pressure, or ignition, and things like that. If it senses something isn't right, it'll shut down the starting attempt.
Fords electric fuel pumps (before push button start), would run a few seconds to build up pressure when key was turned on, and then stop, if you didn't turn the ignition onward into starting mode. So, ... it had fuel pressure senses before push button even came along.

Such as, running out of gas, and needing to turn fuel pump on several times to get all the air out of the system, as you use to be able to do with the mechanical key ignition system. I guess you won't be able to do that anymore, other than running your starter through a series of 5 second trys, trying to get the engine to start.

After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
