At initial cranking it will supply fuel but if there are no ignition events it will either cut spark or fuel (depending on vehicle)... it's a safety feature to shut the engine down (and fuel pump) down in the event of am accident.
I would also try the starter relay... and check your ignition switch. Certain circuits work different whether 'on' or 'start'.

Fuel pump has power for about a second after the engine dies, checked with diode on positive lead on fuel pump plug. Spark plugs are dark black and wet when pulled so assuming its cutting spark. Is there a safety switch somewhere in an event there was an accident that's stopping it from running? I know Fords have an inertia switch not sure about Toyota.
