So I just swapped out my fuel pump via the tank-dropping method. This means that I pulled off the shear panel and in doing so I noticed one of those bolts had a wire attached to it (a bolt on the left of the car). Figured it's just a ground wire, no big deal, just remember to hook it up later.
Well apparently the other end was not screwed into anything so I must have already unhooked it from somewhere. I found the wire laying on the floor a bit later (after moving the tank around, so it jarred it loose). I can't see anywhere within about the length of the wire and in areas that I've been working where it might connect.
It's a fairly short wire - maybe about 12 inches?
On a second note, after I got the new fuel pump in (following this excellent writeup: BOEFabrication.com | Beyond Original Equipment
) I hooked the battery back up and turned the key but didn't get any pump sound. The fuel indicator also reads completely empty.
Seems to me that the mysterious wire could be the ground wire for the fuel pump, especially seeing that I can't see that the fuel tank is grounded anywhere. All of the mounting hardware is insulated from the tank. The fuel pump assembly had the ground wire connected to a flat piece which looks like it was intended to touch the tank opening for ground.
Anyone have any ideas? I'm the world's biggest moron when it comes to electrical, and Lotuses make it even harder since they're all plastic anyway!
Thanks in advance!
