How to understand that the fuel pump is out of order?

The fuel pump is one of the main components of the car - it supplies fuel to the system so that the car can move. On average, there are no problems with it up to 200 kilometers. However, it has its own "whims" and when you buy a used car, you should take this into account.

Experts point out several signs (some of which are tips that should not be done) that indicate that the pump will soon fail.

Reserve

According to experts, you should never spend reserve fuel. This is indicated on the dashboard by a warning light for gasoline remaining in the tank. During operation, the pump heats up. It is fuel that serves to cool it, and work at the load limit leads to overheating and destruction of its parts.

Fuel quality

The fuel pump is sensitive to the quality of the fuel and if there is not enough fuel left in the tank, its filter will quickly become clogged, which will lead to insufficient pressure in the fuel system. However, it is worth considering that the pump does not "die" immediately. The device gives the driver several signals:

• car dynamics is reduced;
• the engine starts unstable or stalls.

Uncertain engine starts in the morning can also indicate a pump malfunction. In this case, if the spark plugs and the battery are in order, the problem often lies with it. Before a breakdown, the fuel pump starts to hum.

When the ignition is turned on, the pump pumps up gasoline, forming the necessary pressure in the fuel system. In the case of a working part, the sound of the pump is not heard during the operation of the motor. But if you turn off the music in the cabin, and you hear a distinct sound coming from under the rear seat, you can freely contact the wizard for diagnosis.
