My BMW K100 was moving up and down the road like a champ then a short run to a convenience store ended up costing 100 bucks in towing fees. The fuel pump simply stopped functioning. The reassuring whir was gone. I think I may have tracked that back to a potential fuel pump relay issue. I removed the battery for charging now when I've replaced it and I attempt to hook up the two poles it attempts to start every time I try to attach the second pole. It does this with the ignition in the off position and even with the kill switch engaged. Does anyone have any idea what's going on and what I can do about it.
