Car fuel pump is an important part, which is responsible for bringing gasoline from the tank to the injector, thereby pushing fuel into the combustion chamber and helping the car operate. If this part is damaged, the motor will lose its capacity and directly affect many other parts and operation of the car. Therefore, to help you quickly identify and test your car fuel pump easily, Thanh Phong Auto Please share the following basic instructions:
Usually, gasoline pumps are very durable. However, when used too continuously or too long, this unit will also encounter some problems:
After operating for a while, the fuel level in the tank will gradually decrease. If the fuel level is too low, the fuel pump will not be cooled sufficiently and will overheat. This can easily cause the fuel pump to be damaged and the check engine light will not be on.
When checking in the port of loading in the engine compartment, if you feel that the gas pressure is lower than normal, it is possible that your petrol pump has a problem in the pipeline or is weakening. This is also the reason why your pet does not work "smoothly".
When starting the car (the ignition is turned ON), if there is no noise coming from the fuel tank area, your car may have the following damage: Damaged fuel pump, A some wiring, the power relay has a problem.

When overworked or contaminated, the fuel pump will not be sufficiently lubricated and cooled. Thereby leading to the risk of the fuel pump unit overheating when the fuel level is too low, causing damage and malfunctions in operation. The performance of the fuel pump is also significantly reduced from contamination.
The easiest sign of recognition is probably the car suddenly stalling while running. After stopping the car for a while, the car can return to normal. Or in the case the car only starts for a few minutes, then engine and can not be started again.
Step 1: Check the fuel pump fuse
You can use your car manual to find out the fuse box and the fuse position of the gas pump:
If the fuse burns: then you replace it with a new fuse of the same ampere level. If after replacing and restarting the car, the fuse still burns, possibly due to a short circuit. You should take the car to the garage for a quick repair.
If the fuse does not burn: Please ask someone to turn on the car keys, and you have to pay attention to see if the fuel pump relay jumps.

Step 2: Check the voltage at the petrol pump
The manual of the car has the Procedures for checking the voltage of the petrol pump to check whether the petrol pump relay is damaged?
Step 3: Use a VOM meter to check for pressure drop
Do you use a VOM meter to check that the power cord and cool cord are sufficient voltage and properly connected? If the results are good, then perhaps petrol pumps are having problems. Please contact the garage for inspection and replacement.
Step 1: Check the gasoline filter
Clogged gasoline filter will cause the car to accelerate slowly. This is easily misleading because you can remove the gasoline filter to check:
