What is a key aspect checked during an ignition system inspection?

During an ignition system inspection, a key aspect that is assessed is the presence of spark. Checking for spark is crucial because it indicates whether the ignition system is functioning properly and capable of igniting the air-fuel mixture in the combustion chamber.

The ignition system consists of various components, such as the ignition coil, spark plugs, and the ignition timing mechanism. If there is no spark or a weak spark, the engine may not start, run smoothly, or may misfire, leading to performance issues. Thus, verifying the presence of a strong and consistent spark ensures that the ignition system is operational and contributing to efficient engine performance.

In contrast, fuel injector performance, float levels, and fuel tank integrity relate to other systems such as the fuel system and lubrication. These aspects are important for overall engine operation but do not specifically address the functionality of the ignition system itself. Therefore, the emphasis on spark presence makes it a fundamental part of an ignition system inspection.
