The second sign: a note of engine vibration and torque weakness
When the petrol pump is weak, it will result in an abnormal vibration in the car’s engine, especially when the car is running while it is stopped, and a weakness in the car’s torque is also noticed due to the failure of the petrol pump to be properly pumped into the engine.

2 – How to check the petrol pump in the car
The way to check the petrol pump in a car is as follows:
First: Make sure whether or not the fuel reaches the engine, by loosening one of the tubes coming from the fuel tank to the engine, which we find connected with clamp clips, after which the switch must be managed and here if the fuel comes out of the tube, the pump is working fine, but if the fuel does not come out The pump does not work and does not push the fuel, and here it is necessary to check the fuse box and ensure the safety of the relay by changing it. If the pump usually works, the problem is in the relay, and if it does not work, we proceed to check the fuse and ensure its safety.
Second: If we find everything good, then we pass to unscrew the negative battery finger, and head to the fuel tank. In most cars, we find the entrance to the pump under the back chairs of the car. Here we disassemble the plug for connecting electricity to the pump and check it well, especially the teeth inside the plug and make sure of Its safety.
Then, if you find everything is good, clean the plug well and return the negative pole of the battery to its place and try to start the car. If it does not work, remove the plug again, and bring a meter or small lamp to make sure that electricity reaches the pump through that plug, turn the switch until The dashboard lights are on and check the plug if there is no electricity, the problem is in the connections, and if you find the electricity connected, the problem is naturally in the pump and here it needs to be repaired or changed.
