Hello - You likely have a shorted coil or ignition module. One of the ignition components is pulling too much current blowing the fuse. Check the coils and ignition module for shorts or other conditions drawing too much current. I would have a certified professional, like one from YourMechanic, inspect the electrical problems and perform needed repairs.
