Repair procedures: Inspection

[Fuel sender] 

1. Turn ignition switch OFF and disconnect the negative (-) battery cable.
2. Remove the fuel pump assembly.

   (Refer to "FUEL PUMP ")

3. Using an ohmmeter, measure the resistance between terminals 5 and 6 of sender connector (A) at each float level.

[Fuel pump three phase coil inspection] 

1. Turn ignition switch OFF and disconnect the negative (-) battery cable.
2. Remove the fuel pump assembly.

   (Refer to "FUEL PUMP ")

3. Using an ohmmeter, measure the resistance between terminals U-V, V-W, W-U.
4. Check that the resistance is within the specification.

   Specification:  0.09 ~ 0.13 Ω

4. Reconnect the negative (-) battery cable.
5. Turn ignition switch ON or cracking at the no-load state.
6. Operate the fuel pump.
   CAUTION:

   • Cranking the Max. 3sec.
7. Check the normal state of the fuel pump.
