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 ...

No Ford engine project is complete without a properly functioning ignition system. This system has the important job of delivering the spark to the required cylinder at precisely the right time. Any ...

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 ...

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 ...

Horse Sense:There's more to a major tune-up than simply throwing in fresh spark plugs. The entire secondary ignition should be checked and replaced if needed. Using a complete system such as the 5.0 ...

Since 1914 auto makers have used the Kettering or inductive ignition system: a battery, transformer (coil), a cam-driven mechanical switch (breaker points), a distributor and spark plugs. The system ...

For the average beginner in the fine art of auto mechanics, and some old-timers as well, installing and wiring a stock eight-cylinder ignition distributor can sometimes be quite a chore, and when he ...

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 ...
