That fuse powers your ignition coil, ignition control module, and fuel injectors. If there's a short in any of the wiring to those components, it would cause the fuse to blow. Just for kicks, try unplugging the coil and see if the fuse stops blowing. That probably isn't the problem, but it only takes a minute to check it.
