Test NS-3A: Checking Engine Mechanical Systems

NOTE: Perform TEST NS-2A  before proceeding.
  1. Check for proper spark plug wire routing and firing order. On 2.0L and 2.4L engines, firing order is 1-3-4-2 with cylinder No. 1 located on passenger side of engine compartment. On 2.5L engine, firing order is 1-2-3-4-5-6 with cylinder No. 1 located on passenger side of engine compartment (rear cylinder head). If spark plug wire routing is incorrect, repair as necessary. Perform TEST VER-1A . If spark plug wire routing is correct, go to next step.
  2. Turn ignition off. Check engine valve timing. If engine valve timing is okay, go to next step. If engine valve timing is not okay, repair engine valve timing as necessary. Perform TEST VER-1A .
  3. Remove all spark plugs. Inspect sparks plugs for wetness caused by fuel. If spark plugs are not wet, go to next step. If spark plugs are wet, clean spark plugs and go to next step.
  4. Check compression on all cylinders. See appropriate SERVICE & ADJUSTMENT SPECIFICATIONS article for compression specifications. If compression is within specification, reinstall all disconnected components. Attempt to start engine. If engine starts and stays running, test is complete. Perform TEST VER-1A . If engine will not start or stay running, go to TEST NS-8A .
