Injector Test
  1. Measure resistance between injector (A) terminals No. 1 and No. 2. There should be 10−13 Ω.
    • If the resistance is OK, go to Step 12 .
    • If the resistance is not as specified, replace the injector.
  1. Check the fuel pressure.
    • If the fuel pressure is as specified, check the following:
      • -
      Whether there is wire breakage or poor connection in the YEL/BLK wire between PGM-FI main relay 1 and the junction connector.
      -
      Whether the junction connector is open or corroded.
      -
      Whether there is wire breakage or poor connection in the YEL/BLK wire between the junction connector and the injector.
      -
      Whether there is any short-circuiting, wire breakage or poor connection in the wire between the injector and the ECM/PCM.
    • If the fuel pressure is not as specified, recheck the fuel pressure.
