Ignition Systems

Master the spark that powers your engine by learning about Automotive Ignition Systems. This critical electrical network is responsible for igniting the air-fuel mixture at the exact microsecond required for peak performance. Our resources cover everything from traditional distributor-based systems and mechanical points to modern coil-on-plug (COP) and distributorless ignition (DIS) technology. Learn how to diagnose weak spark, test ignition coils with a multimeter, and troubleshoot the crankshaft and camshaft sensors that control modern electronic timing. Restore your engine’s power, fuel economy, and smooth idle by mastering the art of ignition diagnostics.
