A week ago I had the described problem, only it was about 40 degrees outside when my car wouldn't start. I checked the fuel pump/alternator fuse under the dash and it was a little lose so I plugged it in all the way and fired right up. Today I am having the same exact problem in the same cold weather after my car has run fine for a week. Do you think that I need to replace my relay? I was thinking maybe there is a relay fuse, but it's not in the fuse box in the engine or under the dash, is there another fuse box I don't know about?

Please help

Thanks,
JP
