My boyfriend owns a 1997 Ford Mustang and I was driving it the other day. When I ws going down the road the ignition fuse blew. I have checked every wire and every time one of us tries to start the car it blows every fuse we put in it. The car tries to turn over but won't start due to the fuse keeps blowing. What should I check next so that we are able to get his ar up and going again.
