Which system would you inspect if there is suspected ignition failure?

When dealing with ignition failure, it's important to consider both the primary and secondary ignition systems as they work together to ensure proper engine operation. The primary system includes components like the ignition coil, ignition switch, and battery, which are responsible for generating the initial spark. If there's an issue here, the spark necessary to ignite the fuel in the engine may fail to occur.

The secondary system, which includes parts such as the spark plug wires and the spark plugs themselves, is essential for delivering that spark to the combustion chamber. If there's a fault in this system, even if the primary system delivers the spark correctly, it may not reach the combustion chamber effectively.

Inspecting both systems allows you to diagnose where the ignition failure is occurring, whether it's a lack of power supply from the primary system or a communication issue in the secondary system. By examining each part of both systems, you can pinpoint the source of the problem and ensure that both systems are functioning correctly, which is essential for proper engine performance.
