[AdelineFitz]

The reasons for insufficient fuel supply in a car include: 1. Incorrect valve timing. 2. Fuel pump: The fuel pump may operate poorly, short-circuit, or burn out due to internal or wiring issues, leading to inadequate or stopped fuel supply. 3. Blocked intake system: For example, the air filter may not allow proper combustion with the fuel. 4. Internal engine faults: Improper maintenance, abnormal wear, or issues with cylinder pressure may cause faults or potential hazards. 5. Blocked fuel system. 6. Spark plugs: Abnormal ignition, aging components, exceeding normal lifespan requiring replacement, carbon deposits, or incorrect model selection. 7. Poor ignition system performance: Such as issues with spark plugs or high-voltage wires.
