WARNING: Without disconnection of injector coupler, combustible gas may come out from spark plug holes during this test and may get ignited in engine room.

2. Remove spark plugs and connect them to high-tension cords, and then ground spark plugs.
3. Crank engine and check if each spark plug sparks.
4. If no spark is emitted, inspect high-tension cords, spark plugs, ignition coil, distributor, etc.
