Fuel Pump Resistance
WARNING: This page is about a different car, the 2002 Lexus RX 300 and 2002 Lexus ES 300. However, it is still accessible from the selected car via links, so may be relevant.
On ES300, measure resistance between fuel pump 2-pin terminals. On RX300, measure resistance between 5-pin fuel pump terminals No. 4 and 5. See Fig 1 or Fig 2
. Replace fuel pump if resistance is not 0.2-3.0 ohms at 68°F (20°C).
