97 Buick Regal keeps blowing the ignition fuse.

Need to trouble shoot the wiring in the circuit that is blowing the fuse, as globalhelper stated. That would be your best start. DON'T put a higher rating fuse in ---unless your looking for a higher rated fire or source of melted wires. although that might pinpoint the source of Original fault a little quicker , right?
