This is my first post on this forum. I just bought my '01 100 two weeks ago and have been lurking on here learning what I can. After reading this thread I looked under my hood to check it out. Whoever had this vehicle before me has run a wire, with an inline fuse, from the positive terminal of the battery, into the fuse box, and into the side of the EFI fuse socket that is closest to the engine. The other half of the fuse socket is open. Looks like it has been there for a good while. I haven't run across this fix yet on the forums but that is what I got. Before buying my 100, I had no idea this was an issue.
