1. Ignition Coil: The ignition coil is located on the top of the engine, near the front of the vehicle. It is a cylindrical-shaped component with a wire running from it to the spark plugs.
2. Control Module: The control module for the ignition system, also known as the ignition control module or ignition module, is usually mounted on the firewall of the vehicle, on the driver's side. It is a rectangular-shaped component with several wires connected to it.
To access these components, you may need to remove some engine covers or other components to get a clear view and reach the ignition coil and control module. It's always recommended to refer to a repair manual specific to your vehicle for detailed instructions on how to access and replace these components.
