What are the reasons for a car not starting due to fuel supply issues?

[AlanaAnn]

There are several reasons why a car may not start: 1. No fuel in the car: If the fuel level is very low or the fuel gauge shows below the red line, the car will naturally not start. 2. Dead battery: A car battery can die due to prolonged parking, reaching the end of its lifespan, generator failure, insufficient or leaking electrolyte, blown fuses, corroded battery terminals, or excessive battery usage. 3. Excessive carbon buildup: Too much carbon buildup can cause poor ignition in the car's spark plugs, leaky valves, and poor fuel injection, leading to misfires, sluggish acceleration, engine shaking, and in severe cases, failure to start. Excessive carbon buildup in the throttle body can block airflow, preventing the engine from starting due to lack of air.
