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 ...

As long as there have been internal combustion engines, there has been a need for an ignition system to ignite the air and fuel mixture in the cylinders. From the earliest days of automotive ignitions ...

An ignition coil is a vital component of a vehicle's ignition system. It is responsible for converting the low voltage from the battery into the high voltage needed to produce sparks at the spark ...

With the engine started and the ignition switch in the run position, a ballast resistor is introduced in the circuit. This resistor is designed to work in conjunction with the primary coil circuit to ...

High-voltage experimenters have been using automotive ignition coils to generate impressive sparks in the home lab for decades, and why not? They’re cheap, easily obtainable, and at the end of the day ...

This ignition coil driver is a HOT one! From my recollection, it delivers a nastier spark than the legendary Ford Model T ignition coil. The circuit uses an inverted 555 oscillator that is coupled to ...

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 ...

Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the ...
