The demands for better emissions and fuel economy in the mid 1970s necessitated leaner fuel mixtures. These leaner mixtures required greater voltage and more spark to ignite. This challenge led GM ...

The ignition control module is a crucial component of a vehicle's ignition system. It is a control unit responsible for regulating the ignition timing and generating sparks to ignite the fuel-air ...

Back in the day, point-triggered ignition system tune-ups were routine and happened roughly every 12,000 miles, along with a set of spark plugs and an ignition timing adjustment. These days, we’re so ...

It seems like such a small thing—that tiny area approximately 0.040 of an inch wide inside each combustion chamber. That area we're talking about is the gap between the electrode and strap on each ...

When General Motors introduced the High Energy Ignition (HEI) distributor in the mid-1970s, it was revolutionary. So much so that it still has a strong following among today's hot rodders. Like other ...

When we first met Steve Davis, owner of Performance Distributors, we knew immediately that he was an out-of-the-box thinker. That's a pretty common characteristic among successful entrepreneurs, but ...

[Dan] wanted to learn a bit about solid state ignition in engines; to get started he needed a test subject, so he decided he would upgrade his old 12 horsepower lawnmower. Originally the lawnmower ...

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 ...

Q: My 2002 Buick LeSabre has 98,887 miles on it. Its ignition control module is failing. Since 2014 I have replaced it three times. Can you please tell why my control module keeps failing? It stops ...

What’s the fastest way to a mental breakdown in your garage, and why is it an ignition issue? No doubt, that stress headache comes on strong when your car was running a minute ago, whereas now it’s ...
