Spark Test

- Disconnect all injector couplers from injectors.

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.

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