What to Do When the Car Doesn't Supply Fuel During Ignition?
2 Answers
The solution to the car not supplying fuel during ignition is as follows: If the car's fuel pump is malfunctioning, it is necessary to promptly visit the car's 4S store or a repair shop to inspect or replace the fuel pump, which can resolve the issue of the car not supplying fuel during ignition. Below is relevant information about the car fuel pump: 1. Introduction: The fuel pump is a lightweight and compact pump, mainly categorized into in-line, distributor, and unit types. The fuel pump requires a power source to operate, and its lower camshaft is driven by the engine crankshaft gear. 2. Classification: (1) Injection type: The injection pump is primarily used in automotive diesel engines. The injection pump assembly is usually composed of the injection pump, governor, and other components installed together as a whole. (2) Self-priming type: Before starting the self-priming pump, fill the pump casing with water or ensure the pump casing itself contains water. After starting, the high-speed rotation of the impeller causes the water in the impeller channels to flow towards the volute, opening the inlet check valve, allowing air from the suction pipe to enter the pump and reach the outer edge through the impeller channels.
As a seasoned driver with twenty years of experience, I've encountered the issue of no fuel supply during ignition a few times. The most common cause is a faulty fuel pump, which might either hum without delivering fuel or not make any sound at all. First, check the fuel level in the tank—don't laugh, some people really do forget to refuel. If there's enough fuel, listen for a slight humming sound when turning the key. If there isn't any, check the fuses; look for one labeled 'fuel' in the engine compartment and try unplugging and replugging it. If that doesn't work, call a tow truck—never risk driving, as breaking down on the highway is extremely dangerous. Additionally, the lifespan of the fuel pump is related to maintenance: regularly replace the filter and avoid letting the fuel tank frequently drop to the red line to prevent many issues. That time I broke down in the suburbs taught me that keeping a spare fuse in the toolbox can be really handy.
