What are the reasons why a car won't start after refueling?

The reasons why a car won't start after refueling include excessive carbon buildup in the throttle body and a faulty crankshaft position sensor. Fuel amount: Generally, filling until the pump automatically stops is sufficient. There's no need to round up the amount and manually add more. After refueling, remember to tighten the fuel cap until you hear a click before leaving. Checking the fuel gauge: Before driving, check the fuel gauge. Based on the distance of your trip and the fuel gauge reading, calculate whether you need to refuel along the way. It's advisable to refuel in advance rather than waiting for the fuel light to come on. The fuel pump is located inside the fuel tank and operates at high temperatures when running continuously. Being submerged in fuel helps to cool it effectively. When the fuel light comes on, it indicates that the fuel level is below the fuel pump. Consistently waiting for the light to come on before refueling can shorten the fuel pump's lifespan, and having too little fuel in the tank may even cause the fuel pump to burn out. Best time to refuel: It's better to refuel in the morning or evening, avoiding the hot midday sun and high temperatures. Since gasoline is charged by volume rather than weight, and it expands when hot and contracts when cold, refueling in the morning or evening allows you to get more mass for the same volume of gasoline, saving you money.
I'm a regular car owner. Last time after refueling at the gas station, my car wouldn't start at all, which really stressed me out. The reason might be impurities or water mixed in the fuel, as low-quality gasoline can clog the fuel system. When refueling too quickly, air intake from the nozzle creates bubbles, causing the fuel pump to fail in drawing fuel. In such cases, don't rush to repeatedly start the engine. You can wait 5-10 minutes for the bubbles to dissipate or check if the spark plugs are functioning properly. If this persists, it can easily damage the engine, so you should take it to a professional repair shop immediately. Prevention is simple: only choose fuel from major brand gas stations and don't go for cheap options. I'll definitely do this myself from now on to avoid breaking down on the road.
