can we back up here. you tried to start the car and the fuse blew. how did you know this had happened? Was it just a wild guess? if you take the fuse out and start the car does it still run rough- if so does that mean the fuse has nothing to do with it? have you checked the obvious plugs wires rotor good fuel... I'd say your next step is to try to eliminate variables. and this blown fuse would be number one on my list, take it out start the car and see how she runs.
