Fuel Pump Inspection

Check the resistance.

1. Using an ohmmeter, measure the resistance between the terminals.
   

   Standard Resistance:

   Tester Connection	Specified Condition
   1 - 2	0.2 to 3.0 Ω at 20°C (68°F)

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

Check the operation.

1. Apply battery voltage to both terminals. Check that the pump operates.
   

   NOTICE:

   1. These tests must be done quickly (for less than 10 seconds) to prevent the coil from burning out.
      
   2. Keep the fuel pump as far away from the battery as possible.
      
   3. Always do the switching at the battery side.
      
   If the motor does not operate, replace the fuel pump.
