FRIDAY TIDBIT: Ignition Control Module

Ignition Control Modules



The ignition control module, located on the engine, regulates the ignition system. It sends power to the ignition coil, which creates a spark that starts the engine. There are several signs of a bad ignition control module.

Poor Acceleration
If the ignition control module is faulty, the car may shake or jerk with increasing speed. Also, the vehicle may seem to slow down instead of speed up when the gas pedal is pressed.

Failure to Start
The vehicle may not start. The engine may turn over but never crank. Also, turning the ignition key may produce a clicking sound from the engine, but no spark.

Overheating
The vehicle may show signs of overheating. If the temperature of the engine rises above normal, the vehicle will lose power. After the engine cools down, the vehicle will start again. If the ignition control module is the problem, the engine will overheat repeatedly, causing further damage that will prevent it from starting at all.

Replacement
A faulty ignition control module results when other parts, such as the spark plugs, fail. Accordingly, a repair shop will check other parts of your vehicle's ignition system for damage. Any parts that are found faulty should be replaced along with the ignition control module to avoid a recurrence of the initial problem.
