  1. Remove air cleaner and airflow meter. Disconnect fuel pump resistor. Ensure continuity exists between terminals "a" and "b". See Fig 1 and Fig 2 .
  2. Measure resistance between the following terminals. Resistance between terminals "c" and "d" should be 60-92 ohms and between "e" and "f" should be .70-.94 ohms. If resistor relay does not test as specified, replace relay.
