What Causes the Car Not to Start and the Fuel Pump Not to Supply Oil?

[SanEliza]

Car not starting and the fuel pump not supplying oil can be caused by the following reasons: Low fuel level: If the car has very little fuel or the fuel gauge shows below the red line, it naturally won't start. When you find that the car won't start, the first thing you should do is check the fuel gauge to see if there's any fuel left. Additionally, never wait until the fuel tank is empty to refuel. This not only affects the engine's lifespan but also the fuel pump's lifespan. Moreover, operating the fuel pump without fuel can be dangerous. Crankshaft position sensor failure: The crankshaft position sensor is one of the most important sensors in an electronically controlled fuel injection engine, especially in centralized control systems. It is also a shared sensor for the ignition system and the fuel injection system. The function of the crankshaft position sensor is to monitor the position of the crankshaft, allowing the engine's computer to detect the speed signal. If the crankshaft position sensor fails, the computer cannot detect the speed signal and thus cannot determine whether to ignite, resulting in the car not starting.
