Good Maintenance Practices:

  • Before replacing a fuel pump, check for proper electrical connections, pressure, and volume.
  • Make a service appointment if your vehicle shows any of the following symptoms: 'Service Engine Soon' light is illuminated, improper engine idling, hesitation, or stalling, excessive exhaust smoke, abnormal engine noises, or noticeable fuel odors.
  • Refer to your Vehicle Owner's manual for additional vehicle maintenance practices.
