Fuel Pump Resistance & Operation (Camry, Sequoia & Tundra)
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Toyota Tundra, 2002 Toyota Tacoma, 2002 Toyota Sienna, 2002 Toyota Sequoia, and 2002 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
- Manufacturer lists checking fuel pump resistance and operation with fuel pump removed from fuel tank and fuel pump mounting bracket. For removal of fuel pump from fuel tank and fuel pump mounting bracket, see FUEL PUMP under FUEL SYSTEMS in REMOVAL, OVERHAUL & INSTALLATION - V6 & V8 article.
- To test fuel pump resistance, using ohmmeter, check resistance between electrical terminals on fuel pump. See Fig 1 and Fig 2 . Replace fuel pump if resistance is not.20-3.00 ohms at 68°F (20°C).
- To test fuel pump operation, on Sequoia and Tundra, reinstall lead wire on fuel pump. On all models, apply battery voltage and ground to terminals for fuel pump. See Fig 1 and Fig 2 . 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 does not 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. Always connect jumper wires to fuel pump and then to the battery when applying battery voltage to fuel pump.
