1. With Ignition OFF, remove the fuel pump relay
2. Measure resistance between terminals 85 and 86 of the fuel pump relay (Component side)
A. Specification : Approx. 70 - 120 ohms at 20 °C (68 °F)
3. Apply 12V and a ground to 85 and 86 terminals of the fuel pump relay (Components side).




4. Check if the main relay works well when it is energized. (If the fuel pump relay works normally, a clicking sound can be heard.)
