Best practices when replacing an ignition control module
The ignition control module must be diagnosed in a logical path, and may require diagnostic scanning in some cases.
Common misdiagnoses
Spark plugs, spark plug wires, ignition coils, and distributor cap and rotor sets are the most commonly replaced components to correct a misfire, even before testing the ignition control module.
A functional fuel pump and fuel filter are commonly replaced in an attempt to solve ignition control module failure due to lack of testing.
Ignition Control Module Replacement Cost Estimates
The average cost for a Ignition Control Module Replacement is between $378 and $485 but can vary from car to car.
