the fuel pump fuse takes a 20amp fuse. it had been working fine, then the car died and wouldn't start. i changed the fuse, it blew immediately. i changed again, blew again, changed one more time. i had to have the car towed home. i let the car sit over night, tried one more fuse, it blew immediately when i tried to start it. this is the only car i have so it is imperative that i find a solution quickly. any suggestions will be greatly appreciated.
