1. INSPECT FUEL PUMP


    A192531E01

  1. Check the resistance.

    1. Using an ohmmeter, measure the resistance according to the value(s) in the table below.

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

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

  1. Check fuel pump operation.

    1. Apply auxiliary battery voltage to terminals 1 and 2. Check that the pump operates.

      NOTICE:
      1. These tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
      2. Keep the fuel pump as far away from the auxiliary battery as possible.
      3. Always switch the voltage on and off on the auxiliary battery side, not the fuel pump side. If the pump does not operate, replace the fuel pump.

      If the pump does not operate, replace the fuel pump.
