Inspection

[Fuel Pump]

1. 1

   Turn the ignition switch OFF and disconnect the negative (-) battery cable.

2. 2

   Remove the fuel pump assembly.

3. 3

   Check fuel pump operation by connecting the fuel pump connector (A) to power (No. 2) and ground (No. 4).

   

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

[Fuel Sender]

1. 1

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

   

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

2. 2

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

   Position	Resistance (Ω)	Capacity (L)
   E	398 ~ 305	2,7
   1/2	85,5 ~ 87,5	23,4
   F	14 ~ 16	44.1

Removal

1. 1

   Release the residual pressure in the fuel line.

   (Refer to Fuel System - "Relieve Fuel Line Residual Pressure")

2. 2

   Remove the rear seat.

   (See Body - "Rear Seat Assembly")

3. 3

   Remove the fuel pump service cover (A).

   

4. 4

   Disconnect the fuel pump connector (A).

   

5. 5

   Disconnect the fuel feed tube quick-connect fitting (A), the vent tube quick-connect fitting (B), and the vapor hose (C).

   

6. 6

   Remove the mounting bolts, then remove the plate cover (A), and remove the fuel pump from the fuel tank.

   Fuel pump plate cover mounting bolt:

   2,0 ~ 2.9 N·m

   

Installation

1. Installation is the reverse of removal.
