I go over symptoms of a failing fuel pump, how to know if your fuel pump is bad or how to know if your fuel pump is going out, and finally, the steps for diagnosing bad fuel pumps. Although, bad fuel pump signs or fuel pump symptoms can appear like other faults, knowing how to tell if you have bad fuel pump or how to diagnose a bad fuel pump is relatively easy as symptoms of bad fuel pumps in addition to basic tests is all you need to nail the diagnosis. If you are asking what are signs of a bad fuel pump or a clogged fuel filter or you are having problems with codes: P0171, P0174, P0231, P0087, P0232 etc, you will find this video helpful.
