3 | Fuel sender ground (-) |
4 | Fuel pump (+) |
5 | Fuel pump (-) |
Turn the ignition switch OFF, and then remove battery (-) terminal.
Remove the fuel pump assembly.

Also check that the resistance changes smoothly when the float is moved from "E" to "F".
Position | Resistance (Ω) | Capacity (ℓ) |
E | 197 ~ 203 | 3 |
1/2 | 64.2 ~ 68.2 | 24.6 |
F | 7 ~ 9 | 49 |
Turn the ignition switch OFF, and then remove battery (-) terminal.
Remove the fuel pump assembly.
(Refer to Fuel Pump - "Removal")
Check that motor operates properly when battery voltage is applied to terminals 4 and 5 of fuel pump connector (A).
