Common Symptoms
- A failing fuel pump will not create enough pressure in the fuel system, potentially resulting in a loss of engine power or a “no start” condition. You may also have a lean running condition that can set a diagnostic trouble code and turn on the Check Engine Light.
- Fuel pumps require replacement if they leak or begin making too much noise, which is a sign of malfunction.

Common Misdiagnoses
- A clogged fuel filter or problems with the electrical system powering the fuel pump can result in symptoms similar to a failed fuel pump. Have the shop verify that the pump is the problem before replacing.
Best Practices
- The fuel filter should always be replaced when replacing the fuel pump.
