Why won't the car start when it's out of engine oil?

[DelMicah]

The reasons why a car won't start when it's out of engine oil are as follows: 1. Circuit or electronic failure: Circuit failures include blown fuses, open high-voltage coils, open low-voltage circuits, detached central ignition wires, leaking distributor rotors, and damaged spark plugs. Electronic failures mainly refer to the central computer control board losing functionality. 2. Fuel system failure: Engine shutdown caused by fuel system failures often exhibits symptoms such as weak engine power and a throttle pedal feeling like stepping on cotton. Possible locations of fuel system failures include: fuel pump failure, blocked fuel lines, clogged fuel filters, carburetor failure, damaged injectors, etc. Sometimes, the fuel tank may be empty without the owner's knowledge.
