Ford focus 2002, 2 litres, what is the function of the pick up coil

The pick up coil is located at the base of the distributor and plugs into the ignition module. The pick up coil's purpose is to sense or "pick up" the pulses of the distributor and tell the ignition module when to fire the spark plugs. The most critical part of the replacement of the pick up coil is to make certain you properly mark the orientation of the distributor to the engine block and the rotor to the distributor base. When you successfully make these markings, you will not need to check your timing when this job is finished. Keeping this in mind, here we go: You will need to purchase a replacement pickup coil and a rubber o-ring gasket that will replace the o-ring located where the distributor shaft enters the engine before you start this project.
