    If the resistance is not as specified, replace the injector.
2. Inspect the injection volume.
  CAUTION: This test involves high - pressure fuel and electricity. Take every precaution regarding safe handling of both the fuel and the electricity. Perform this test in a safe area, and avoid any sparks or flames. Do not smoke.
