1998 Mercury Mystique no power to the starter?

Do you think the security system is causing a problem? You can check voltage circuits to the starter relay. Usually voltage to the load side of relay is hot all the time, voltage to the coil side of relay goes hot with key in the crank position. Ground for the coil side of relay, automatic, goes through the trans range sensor, then where applicable, through the theft module.

ignition switch is probably shot, try jumping starter. If starter cranks then suspect faulty switch.
