Got a 1987 4runner 22re, been having issues with my battery dying, traced it down to the 15 amp efi fuse in the driver's side kick panel. I have a 12 amp draw whenever the fuse is plugged in, o2 sensor wire isn't the issue, main efi relay isn't either, disconnected everything running to the fuel pump and still have the draw. Not really sure what else to check. any help?
(Fuse has never blown just draws power)
