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:

Instructions for Checking Gasoline Pump For Cars
1. Signs that Gasoline Pump Is Damaged
Usually, gasoline pumps are very durable. However, when used too continuously or too long, this unit will also encounter some problems:
The pump is overheated
After operating for a while, the fuel level in the tank will gradually decrease. If this level is too low, the pump will not be cooled sufficiently and lead to overheating. This makes it easy for the gas pump to be damaged and the engine to check will not turn on.
The ability to pump gasoline is weakened
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".
There is no noise in the gas tank when starting
When starting the car (the ignition is turned ON), if there is no noise coming from the fuel tank area, your vehicle may have the following damage: Damaged gasoline pump, Some cables, electrical relays have problems.
The pump is contaminated
When working overloaded or contaminated, the petrol pump will not be lubricated and fully cooled. This leads to the risk of the petrol pump getting too hot when the petrol level gets too low, causing damage and malfunction. The performance of the petrol pump also greatly reduces contamination.
Vehicles with sudden signs of stalling
The easiest indication is probably the sudden death of a car while driving. When stopping for a while, the vehicle can return to normal. Or, in case the car only starts a few minutes later, the engine and cannot restart again.
2. So, How to Check the Oto Gasoline Pump?
Check the electrical system section of the petrol pump
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.
Check the fuel pressure section of the petrol pump
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:
- Remove the gasoline filter and remove the gasoline that remains in the filter.
- Use an air gun to blow into the holes to see if the residue is coming out. If so, it is necessary to change the filter.
Step 2: Use a pressure gauge to check the operation of the petrol pump
- Pressure gauges are often sold at automotive parts stores. Pressure gauge is used to check the operation of the petrol pump when the vehicle is started.
- Use the user guide to attach the pressure gauge to the petrol pump test connector (because each meter has a different head, each vehicle also has a different pump position).
- Run the engine and check the pressure on the meter. If the pressure varies with engine speed, the petrol pump works well. In contrast, petrol pumps are having problems and need to be replaced.
Understanding and testing your pet driver will help you flexibly handle in case of unexpected vehicle damage. Especially simple parts such as petrol pumps. Hopefully the above sharing of Thanh Phong Auto will be helpful to you. Wish you always have interesting experiences with your pet driver!
