Ignition Module location

Good afternoon.

There is no ignition control module. The ECM controls the spark based on the input from the distributor pick up coil.

Description below.

This coil supplies the basic timing signal to the computer. The computer also uses this signal to determine engine RPM, location of piston during compression stroke and when engine is in cranking mode. In-line six cylinder and V8 engines can use one or two pick up coils depending on application. The start pick up coil, located on the distributor, signals the computer to fire the spark plugs at a fixed amount of advance during cranking only. The amount of advance is determined by the position of the start pick up coil. The run pick up coil is used by the computer to monitor engine speed and crankshaft position after the engine has started.
