Reasons for the Fuel Pump Not Supplying Oil and the Car Not Starting

[LaAdriana]

There are usually several reasons why a car won't start: 1. No fuel in the car: If the fuel level is low or the fuel gauge shows below the red line, the car won't start. 2. Crankshaft position sensor failure: The crankshaft position sensor is the most important sensor in an electronically controlled fuel injection engine, especially in centralized control systems, and is also a shared sensor for the ignition and fuel injection systems. Its function is to monitor the position of the crankshaft, allowing the engine's computer to detect the speed signal. If the crankshaft position sensor fails and the computer cannot detect the speed signal, it cannot determine whether the vehicle is attempting to start, resulting in the car not starting. 3. Starter motor failure: If the car exhibits the following issues, it is advisable to check if the starter motor is faulty: 1. After pressing the ignition switch, the starter motor spins at high speed, but the engine does not respond. 2. After pressing the ignition switch, the starter motor does not react. This could be due to wiring issues, a burnt battery power supply line, or a damaged starter relay. 4. 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 overuse of the battery, all of which can prevent the car from starting. 5. Excessive carbon buildup: Too much carbon buildup can cause problems with the car's spark plug ignition, leading to poor valve sealing, misfires, weak acceleration, engine shaking, and in severe cases, the car not starting.
