Ok heres what happened. My fuel pump fuse blew out. We replaced the fuel pump awhile back so I know it's not that. We had all the wires connected from the front to the back and NOTHING is loose, corroded, or in need of replacing. Popped a new fuse in and has been flawless for three days. Why do you think the fuse blew out? Could it have been a possible bad fuse? I am guessing these things are original. I don't think that fuses really wear out unless they blow but....just a freak accident?
Second quiestion. I hear you can buy a "breaker" for a car so that if it did blow out again, the car would start right back up because it is not like a fuse to where you have to replace it. Any information on this? JUst a thought... |

I've had a fuse blow for seemingly no reason on my taillights. Couldn't find a problem. Replaced it and haven't had problems since. It is a 20 year old car, after all, and there are bound to be little gremlins in it. As long as you checked everything and it seemed ok, I wouldn't be too concerned.
As far as a "breaker" - why would you want that?? Sounds like a bad idea to me. The whole point of a fuse is to protect the system it is in line with. If you had a breaker that kept tripping, that would defeat the purpose. It would just cover up whatever problem there was without solving it. Could cause more problems in the long run. There are "breakers" for mechanics/testing use that you can replace a fuse with for diagnostics, but I wouldn't want one full time in the fuse box. Just my $.02. Matthew |

Could be a fluke. A little overcurrent on the motor starting could have been enough to do it in. Corrosion on the contacts will heat up the contacts, but won't hurt the fuse.
You can get slow burning fuses also, on these the little fuse element looks like a wide "S" shaped ribbon with a small hole in the center, takes a little bit longer of an overcurrent to blow them. |

If the new pump is a higher performance pump the stock wiring is kinda wimpy, so an upgrade to larger wire is mandatory for aftermarket pumps IMO.
