If sparks are available, it would most likely be mechanical or fuel that is causing the non starting.
If it is fuel related could it have just quit without any indication?
A failed fuel pump or its controlling circuit would cause the engine to quit without any indication.
Inertia fuel shut off switch would stop the fuel pump from operating. It is designed to be activated in the event of a collision and to reset it, you have to manually depress the button on the switch.
