I would start by checking if the under dash fuse panel is getting power to all the fuses. A few will be hot at all times (like the brake light fuse, horn fuse), but with key on, all fuses in the fuse panel should have power available to them.
Use a test light, clip the ground clip to a metal bracket, and use the test light probe to touch the fuses at the ends-the little indents on top of fuse is open to the metal strip in the fuse. When the probe touches that strip, the test light should light, meaning power is getting to the fuses. No light? Maybe not grounded good-keep trying until you get a light when touching the fuses through that little **** at top of fuse. When you have a good ground, check all fuses. With key on, all fuses should have power-now you can check the radio fuse and dash fuse.
You can do this also to check for a blown fuse. Even a blown fuse will light the tester on one end of fuse. A good fuse will light tester on both ends of fuse. A blown fuse will only light tester on one end. You can check fuses this way without pulling the fuse out to inspect.
If no power to the fuse panel or to part of the panel, look for a bad fusible link or maxi fuse that distributes power to the fuse panel. There may also be a relay (ignition relay) that the key switch turns on to send power to the fuses that are hot in accessory or run.
