One of the top causes for fuel pump failure is contamination. This can be caused by dirt and debris entering the system from re-fuelling or the use of poor quality fuel. Fuel pump overheating and wear can also cause failure. Driving frequently on a low fuel tank can accelerate wear on the fuel pump due to debris on the bottom of the fuel tank being disturbed and entering the pump. It is interesting to note that over half of all fuel pump replacements are the result of misdiagnosis. The complexity of modern vehicles leads to several systems that can disable the vehicle‘s fuel pump. Systems that one would not normally associate with the fuel system now have the ability to render the fuel pump inactive (e.g. security, drive train, oil / fuel pressure switches, etc.), which can result in a mis-diagnosis.
