* Drained Battery: The most immediate concern is that your battery will be completely drained if the fuel pump runs continuously. It will eventually die, leaving you stranded.
* Fuel Pump Failure: Constant running puts excessive strain on the fuel pump, leading to premature failure and potential costly replacement.
* Other System Malfunctions: The problem could stem from a faulty fuel pump relay, a short circuit in the wiring, or a problem with the PCM (Powertrain Control Module) itself. These issues are more complex and require professional diagnosis.
* Fire Hazard: While less likely, a constantly running fuel pump could overheat and potentially pose a fire risk, especially if there are other underlying electrical issues.
You should not drive the vehicle until this is fixed. Take it to a qualified mechanic immediately to diagnose and repair the underlying cause. Continuing to drive it risks significant damage and potential safety hazards.
