Here are some possible causes:
* Faulty ignition switch: The ignition switch is responsible for turning on and off the power to the fuel pump. If the ignition switch is faulty, it may not be able to properly turn off the power to the fuel pump, causing it to continue running.
* Stuck fuel pump relay: The fuel pump relay is a switch that controls the power to the fuel pump. If the fuel pump relay is stuck in the "on" position, it will cause the fuel pump to continue running.
* Wiring issue: There may be a wiring issue that is causing the fuel pump to continue running. For example, a loose or damaged wire could be providing power to the fuel pump even when the key is not in the ignition.
If you are experiencing this problem, it is important to have it diagnosed by a qualified mechanic to determine the cause and prevent further damage to your vehicle.
