Your 2000 Focus' ignition system is comprised of the ignition switch, the battery, several sensors, the ignition coil, and the spark plug wires and plugs. These are all linked to the car's fuel injection system and the Powertrain Control Module.

Starter Circuit and Components
If your Focus' engine is not turning over at all, it could mean that you have a faulty battery or starter. Have your battery tested for charge and/or the starter motor and solenoid tested. Otherwise, you could have an opening in the starter circuit, which can be tested for using a high-wattage test light.
The components in the ignition system are mostly electrical, such as the sensors that send the Powertrain Control Module information to regulate the ignition timing. If the engine is turning slowly, misfiring or won't start, you may want to check all electronic connections to see if any are loose, filthy or damaged.
Spark Plugs and Wires
The spark plugs and spark plug wires can be the cause of a few different ignition problems such as when the engine will not start, engine misfires and lack of engine power. You may want to inspect and/or replace the spark plugs and their wires if starting problems, as well as other engine problems, occur.
