How to check the booster pump?
Content
The booster pump is the link between the fuel and your car's engine. It is also known as fuel pump, fuel pump or gasoline depending on your fuel type. Set on fuel tank, this guarantees optimal fuel supply to the engine. Without it, the engine will not be able to power properly and it will be difficult for you to start it, stop it regularly, or even hear the noise coming from the tank.

Step 1. Check the booster pump fuse.
In many cases, there is power problem at the level of the booster pump. Using the manufacturer's manual, locate the fuse box as well as the one that matches the booster pump. If you notice that the fuse damaged, brulee or that the lead of this has melted, it will be necessary to replace this fuse. It is important that this new fuse has the same strength as the previous one. If the fuse is blown, it will be necessary to determine splash source.
Step 2: Measure the voltage across the pump
To be sure the current reaches your booster pump, you should measure the voltage at this level using multimeter... To do this, refer to your vehicle manufacturer's manual, because voltage measurement can be done differently depending on your vehicle model.
Step 3: Measure the voltage at the pump fuse.
For this operation, you will need a multimeter again to make sure that the current and weight work properly on the pump. The standard required for voltage indicated in your manufacturer's manual, if the test result shows a difference of one volt more or less, the problem is electrical circuit de la Pompe.
Step 4. Check the booster pump relay.
The problem could also be relay pump. To check this, you must remove the relay from it connector then define the control terminals on the relay. Put the multimeter in measurement mode ohmmeter then measure the resistance value between the terminals.
Step 5: Conduct a Fuel Pressure Check
Locate the pump so that the pressure gauge snaps into place. It is usually located near the nozzles. The pressure gauge must be connected to airtight seal located next to the booster pump.
A man must press the accelerator pedal when performing this test so that you can check the fuel pressure when the engine is idling and at higher rpm. Compare the measured values with the values recommended by your vehicle manufacturer.
If the pressure gauge needle does not move when the engine is running, the pump is running. failure.
A booster pump is required to supply fuel to the engine. If it is defective or its fuse no longer blows, the pump should be replaced as soon as possible to save the motor and all parts of the system to which it is connected.
