Turn the ignition switch OFF, and then remove battery (-) terminal.
Remove the fuel pump assembly.
Using an ohmmeter, measure the resistance between terminals 1 and 3 of sender connector (A) at each float level.
Pin No. | discription |
1 | Fuel sender signal (+) |
2 | Fuel pump (+) |
3 | Fuel sender ground (-) |
4 | Fuel pump (-) |
Also check that the resistance changes smoothly when the float is moved from "E" to "F".
Position | Resistance (Ω) | Capacity (ℓ) |
E | 197 ~ 203 | 4.3 |
1/2 | 64.2 ~ 68.2 | 26.4 |
F | 6 ~ 10 | 51.3 |
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 2 and 4 of fuel pump connector (A).
