1. The function of the gasoline pump in an automobile engine

If “blood” plays an important role in determining the life and development of each person, gasoline will also play an equally important role when deciding whether the car can move or not.

Fuel pump is a system that connects the fuel tank with the car’s engine cluster. This is an indispensable part that is responsible for drawing gasoline from the tank and then pushing on the hose to provide fuel for the equipment on the vehicle to operate.

This pump system is designed to be placed in the fuel tank, but in some variants, the pump system is 1 unit located inside and one outside the tank. According to research, experts make judgment according to the variation to maintain pressure in the fuel tank from 2.0 to 5.8 atmospheres.

If this pressure is too low, it will affect the fuel pump process, causing the car to start difficult, particularly the car ignition is not good, the engine works irregularly, even stops the engine.

After a period of using the fuel pump system, dust will cling to the car leading to sediment in the tank, combined with the cold engine early in the morning, it will be difficult to start. If you often have such problems, you need to check your gas pump system and have solutions promptly.

The reason may be that the engine is not supplied with enough fuel, which makes it impossible to ignite.
  • In another case, when you go at high speed, the car feels jerky or feels like losing gas, because the engine cluster is not supplied with enough fuel.

3.How to handle when a car is pumped out loud

Part 1: Check gasoline pump electrical system part.

The fuel pump system is a closed device designed in the fuel tank, so it rarely fails, if this happens, it will happen to the system supplying electricity to the petrol pump. Now you should check the fuse box and find the fuse of the gas pump electrical system to check.

Once you find the fuse on the gas pump, remove it and check if the device is valid. If the fuse is burned, replace the fuse with a new one. If the fuse is still valid, turn on the car key and feel to see if the gas pump jumps as normal or not.

Step 2: Buy pressure gauge.

If possible, you should buy yourself a watch to measure the pressure in the fuel tank, the pressure is also one of the reasons affecting the vehicle’s movement.

Step 3: Attach the pressure gauge to the gas pump test connector.

Once you have a pressure gauge, you attach this device to the connector to determine the fuel pump pressure, but each type of meter has a different usage you need to refer to in advance to use. achieve the best quality performance.

Step 4: Run the engine when you check the clock.

After attaching the meter to the connection position of the fuel pump assembly, you let the car start with two modes of idling and acceleration and check the pressure. If the pump is working properly, the pressure on the meter will change with the engine speed. If the pressure is constant, the fuel pump is having problems and needs to be replaced.

Above are our share of the error “The car’s gas pump goes out loud”, in particular, the gas pump cluster is having problems with solutions and checks to avoid causing heavy damage to the owner.
