The car is a 1993 240SX convertible w\ stock K engine. It sat outside (covered) last winter and this summer. I started it with a portable booster and it fired right up. Great car! It ran for 5 minutes and shut off. After digging around, I found the fuel pump fuse (under the hood) had blown and kept blowing as soon as I turned it over. It was running fine and this I think has something to do with being left out in a New England winter, but I'm stymied. Any help would be greatly appreciated. I have the factory manual but the fuel pump troubleshooting is pretty lame.

Thanks!
