If the battery is shorted,(junk) you may not be able to jump through it. Save time and money borrow a ford batter from a buddy (that is full charged) swap it with yours. See if it starts. Also make sure all connections are clean.
Agree with answer above. Turn on the ignition switch to the on but not run position do you see an icon on the instrument panel representing a battery, if you do not see this battery icon the alternator is not seeing power to allow it to charge. Start the engine does the battery icon go out. . Put a volt meter across the battery terminals with the engine off, at rest the battery voltage should be 12.6 volts if the battery is fully charged. Now get a friend to start the car while you watch the voltmeter, the voltage reading across the battery should read approximately 14.6 volts if the alternator is charging correctly.
