The P0351 code means your engine control module (ECM) has detected a malfunction in the ignition coil “A” primary/secondary circuit, which corresponds to cylinder 1 on most engines. When this circuit ...

A windings road:It all starts with the concepts of inductance and electromagnetism. Inside an ignition coil there are two sets of wire windings (aka coils, that's why it's called a "coil," get it?).

Heat initiates the internal combustion process. Diesel engines utilize the temperature buildup from extremely high compression (pressure) to ignite the air/fuel mixture, with a little help from glow ...

Out of the many different aspects of the Pontiac hobby, ignition-system function is often the most misunderstood. Since it deals with an intangible (i.e., electricity), it's very easy to assume one ...

Ignition coils play a crucial role in a vehicle's ignition system as essential components that facilitate the engine's combustion process. They are responsible for converting the low voltage supplied ...

Ignition issues can be a real pain to both diagnose and deal with. Sure, generally speaking, having a faulty ignition coil is a better problem to have than a worn-out turbo or clogged DPF, but ...

Ignition coils sit at the center of every gasoline engine’s spark, yet they usually stay invisible until something goes wrong. When a coil starts to fail, the symptoms can look like fuel problems, ...

Ignition coils play a crucial role in a vehicle’s ignition system. They serve to convert the battery’s low voltage into the high voltage necessary to fire the spark plugs. If there’s any malfunction ...

When you’re trying to learn about older cars, you might as well be signing up for the debate club. Every question, especially when it comes to breaker points, electronic, and multiple spark discharge ...
