I have a 1998 Pontiac Sunfire that will blow the fuel when it is raining, snowing, etc. I have had the fuel pump checked and it is good. Dealer said that the fuel filter was clogged and replaced it. They said that it was the problem, but it has quit again(a rainy day). What could be causing this to happen, a frayed wire?

Well why does a fuse blow? To many amps. Think of amps like gallons of water per minute. Sometimes Amps are represented as I for intensity on schematics. The must likely cause for a blown fuse is a short to ground. A short to ground means that current bypasses the intended path and flows directly to ground. There is a wire some where on you car that is exposed. I will assume that the fuse also feeds other circuits so there is probaley some other things on your car not working find out what those are and you can began to narrow your search. If you can read a schematic you are way ahead of the game.
