There are a few possible causes of a fuel pump failure, including:
* Electrical problems: The fuel pump is powered by an electrical circuit, so any problems with this circuit can cause the pump to fail. This can include issues with the wiring, fuses, or relays.
* Mechanical problems: The fuel pump is a mechanical device, so any problems with its internal components can also cause it to fail. This can include issues with the pump's impeller, diaphragm, or seals.
* Fuel contamination: If the fuel in the tank is contaminated with water or other contaminants, it can cause the fuel pump to fail. This is because the contaminants can damage the pump's internal components.
If you see the fuel fail 69 code on your VCM, it is important to have your vehicle diagnosed by a qualified mechanic. They will be able to determine the cause of the fuel pump failure and repair it so that your vehicle can run properly again.
