Fuel Pump Resistance & Operation
- Disconnect electrical connector for fuel pump. See FUEL PUMP ELECTRICAL CONNECTOR LOCATION table. This is electrical connector for fuel pump and fuel gauge sending unit.FUEL PUMP ELECTRICAL CONNECTOR LOCATION
Application Electrical Connector Location Camry, Camry Solara, Celica & Corolla Under Cover Plate, Below Rear Seat RAV4 Under Cover Plate, Below Driver's Side Rear Seat Tacoma & 4Runner On Top Of Fuel Tank At Fuel Pump - To test fuel pump resistance, use ohmmeter to check resistance between specified terminals on fuel pump electrical connector or fuel pump. See Fig 1-Fig 6 . Replace fuel pump and/or lead wire (if equipped) if resistance is not.20-3.00 ohms at 68°F (20°C).
- To test fuel pump operation, apply battery voltage and ground to (+) and (-) terminals on electrical connector or fuel pump. See Fig 1-Fig 6 . 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.
CAUTION:
When testing fuel pump operation, DO NOT apply battery voltage to fuel pump for more than 10 seconds or fuel pump may be damaged. When testing fuel pump operation, keep fuel pump away from battery as far as possible.
