    ”He” would be pretty long in the tooth since most cars for the last 30 or more years had fuel injection. I would go to another shop.

    It could be a shorted wire in the ignition, injector circuits supplied by the am2 fuse. The ignition switch is part of the circuits, and fuel pump. The am2 is ok? Then the fuses after the am2? The basics of spark, gas, and air still apply. If it has those it fires. Need a wiring diagram. If all fuses good and no shorts, go to each component and test.
    I’ve seen people furiously pumping the gas when their newer car won’t start. Like was said, those days are over.

    I don’t know about the Prius 30 (I haven’t dealt with this yet), but the symptoms are similar to a clogged exhaust system. A melted or broken catalytic converter that has blocked the exhaust.
    You can remove the air/fuel ratio sensor or one of the spark plugs, also disconnecting the coil, start it and see if the engine would run any longer.
    Also you can check the pressure in the exhaust system by installing a pressure gauge into the place of the air/fuel ratio sensor.
