What should I do if my car doesn't start after refueling? Why doesn't the fuel gauge rise after refueling?

When the car is out of gas or running low on gas, you need to refuel, especially when driving. So what is the reason why the car won't start after refueling? Sometimes the fuel gauge warning light will turn on. Let's learn about it together.

What to do if the car does not start after refueling

First check if your car still has power. If it does, check the gas pump in your tank. This needs to be done by a professional. If your car is out of gas and you keep starting it over and over, or the gas pump is overheated, it will break down.

In addition, many people often use up the oil in the fuel tank until the fuel gauge light comes on, thinking that this will use up the oil deposited in the fuel tank. This may cause the fuel pump to overheat and cause it to break down.

Why does the fuel gauge not rise after refueling?

The oil position sensor is a variable potentiometer. It is possible that it is stuck, or that the signal line has poor contact when refueling, or that the contact and the scriber have poor contact. You can open it and check the float and move it, which can usually solve the problem.

When the oil is full, the float will move to a relatively high position, which will cause the contact and the scribe to move to the edge or become detached.

Why can't the vehicle start?

Ignition system failure may be caused by failure of the ignition module, spark plug, damage to the ignition module, excessive spacing between the spark plug rods, or cracking of ceramic parts.

Fuel system failure may be caused by a fuel pump failure. Check the circuit for abnormalities. It is also possible that the fuel pipe is clogged and the fuel injector is not pumping fuel.

Starting system failure, such as starter motor or battery damage.
