Fuel Pump Resistance & Operation (Camry Solara, Celica, Corolla, ECHO, Highlander, MR2, Prius, RAV4 & Tacoma
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Toyota Tacoma, 2002 Toyota RAV4, 2002 Toyota Prius, 2002 Toyota MR2, and 2002 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
On Prius, read service precautions before proceeding with service procedure. See SERVICE PRECAUTIONS .
- On Camry Solara, Celica, Corolla, ECHO and Prius, remove rear seat cushion, cover plate on floor panel and remaining necessary covers for access to electrical connector for fuel pump.
- On Highlander, remove driver's side and passenger's side rear seats and cover plate on floor panel for access to electrical connector for fuel pump.
- On MR2, remove luggage compartment lids, quarter trim covers, lower trim covers and luggage compartment boxes behind driver's and passenger's seats, and cover plate on floor panel for access to electrical connector for fuel pump. See Fig 10. For additional information on removal of luggage compartment components, see FUEL PUMP under FUEL SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article.
- On RAV4, remove driver's side rear seat and cover plate on floor panel for access to electrical connector for fuel pump.
- On Tacoma, it may be necessary to lower fuel tank for access to electrical connector for fuel pump.
- On all models, disconnect electrical connector for fuel pump. This is electrical connector for fuel pump and fuel gauge sending unit and is located on top of fuel tank, near fuel pump.
- To test fuel pump resistance, using ohmmeter, check resistance between specified terminals on fuel pump electrical connector or fuel pump. See Fig 1-Fig 9 . Replace fuel pump if resistance is not .20-3.00 ohms at 68°F (20°C). On Prius, it may be necessary to replace fuel pump and fuel tank as an assembly. Consult parts department for parts availability. See FUEL PUMP under FUEL SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article.
- To test fuel pump operation, apply battery voltage and ground to (+) and (-) terminals on electrical connector or fuel pump. See Fig 1-Fig 9 . DO NOT apply battery voltage to fuel pump for more than 10 seconds. Replace fuel pump and/or lead wire (if equipped) if fuel pump fails to operate. On Prius, it may be necessary to replace fuel pump and fuel tank as an assembly. Consult parts department for parts availability. See FUEL PUMP under FUEL SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - 4-CYLINDER article.
CAUTION:
When applying battery voltage to fuel pump, DO NOT apply battery voltage for more than 10 seconds or fuel pump may be damaged. Keep battery as far away from fuel pump as possible. Always connect jumper wires to fuel pump first, and then to battery, when applying battery voltage to fuel pump.
