It sounds to me like the ignition lock cylinder is not rotating enough to turn the electrical part of the ignition switch, based on your being able to start it with a screwdriver but not with the key. Loosen the ignition switch and see if you can rotate it clockwise to try to reach the point where turning the lock cylinder will engage the starting contacts.

When you replaced the ignition switch, did you install a Mitsubishi or an aftermarket part?
