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 ...

Let’s start by looking at the evolution of the GM High Energy Ignition (HEI) system. This system became available as an option in 1974 and was standard in all 1975-and-later vehicles, with the ...

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 ...

If you have a classic, vintage, or otherwise old car, you've probably heard of the distributor that it features. It's part of the ignition system that transfers current from the battery to the ...

Firepower's smarter sparks are generated by this sealed ignition module which contains an integrated circuit (IC) chip known as an EPROM. Each unit's Erasable Programmable Read Only Memory chip is ...

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 ...

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 ...

Q. I've noticed my new car doesn't have a distributor or spark plug wires, unlike every other car or truck I've ever owned. Can you explain how this works? A. This is one of the neatest automotive ...

The Series 9X microprocessor-based intelligent direct spark and intermittent pilot ignition control modules are designed for OEM and replacement for natural, manufactured gas, or LP applications. The ...

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 ...
