I bought a car last weekend from Florida that has a Buschur double pump setup in it installed by AWDMotorsports. My wife called me at work this morning and said the car was making a weird noise but was off. I came home and found that the fuel pumps were running. I pulled the fuse from the wire attached to the battery (wired to the fuel pumps) and they turned off. I won't have time to look at the car until the weekend but figured I'd check to see if anyone has seen this before. Any ideas?

 

Hobbs switch might be stuck in the on position. I had the same problem, ended up buying a replacement from Napa.

 

Thanks!!! I just got home and followed the power wire off the battery all the way to the hobbs switch. Sure enough, it was severely corroded. I hooked the power back up to it and the fuel pump turned on. I then flicked the switch with my finger and no more fuel pump. The installer did a good job hiding it and I would have spent hours trying to figure it out. I really appreciate your help.
