Inspection

1. 1
   Turn the ignition switch OFF and disconnect the negative (-) battery cable.
2. 2
   Remove the fuel pump assembly.
3. 3
   Check the fuel pump operation by connecting the fuel pump connector (A), applying power to pin (No. 2) and ground to pin (No. 4).

   

   Pin No.	Description
   1	Fuel sensor signal (+)
   2	-
   3	Fuel sensor ground (-)
   4	Fuel Pump Motor (+)
   5	Fuel Pump Motor (-)

4. 4
   Using an ohmmeter, measure the resistance between terminals 1 and 3 of the sender connector (A) at each float level.

   

   Pin No.	Description
   1	Fuel sensor signal (+)
   2	-
   3	Fuel sensor ground (-)
   4	Fuel Pump Motor (+)
   5	Fuel Pump Motor (-)

5. 5
   Also check that the resistance changes smoothly as the float moves from the "E" position to the "F" position.

   Position	Resistance (Ω)	Capacity (L)
   E	298 - 305	3.0
   Cluster Indicator Lamp	188 - 192	6,6
   1/2	80,4 - 84,4	18.2
   F	14 - 16	33,7
