Fuel Pump: Inspection

1. INSPECT FUEL PUMP 
   1. Check the fuel pump resistance.
      1. 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. Check fuel pump operation.
      1. Apply battery voltage to terminals 1 and 2. Check that the pump operates.
         NOTE:

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