A power drain is caused by a wiring fault somewhere. Hook up a voltmeter or test light in series with the negative battery wire and terminal, pull all fuses but one, and reinsert them until it shows there is current flowing. This way, you'll know which circuit is draining your battery. Look in your owners manual fuse diagram and see what that fuse operates. Check the component and its wiring.
Note: While testing, do not do anything that will draw a large amount of current (eg. headlights, accessories, starter). Do this test with the ignition OFF.
Fuel filter and spark plugs are very easy. Check out the autzone website's Contour repair guide or a service manual, you'll find illustrated step by step instructions.
