INSPECTION 

1. INSPECT FUEL PUMP ASSEMBLY
   1. Inspect the resistance of the fuel pump.
      1. Using an ohmmeter, measure the resistance between terminals 1 and 2.

         Standard resistance: 

         0.2 to 3.0 Ω at 20°C (68°F) 

         If the result is not as specified, replace the fuel pump.

   2. Inspect the operation of the fuel pump.
      1. Connect the battery's positive (+) lead to terminal 1 of the connector, and the negative (-) lead to terminal 2. Check that the fuel pump operates.
         NOTE:

         • These tests must be performed within 10 seconds to prevent the coil from burning out.
         • Keep the fuel pump as far away from the battery as possible.
         • Always turn the voltage on and off on the battery side, not the fuel pump side.
