got a 89' rs wit a 2.8 v6 in it. when car is off it keeps makin a huming noise. i believe its either the fuel pump or the throttle body but not really sure. i believe this is the reason for my cars battery to keep dieing over night. any help would be apprieciated.

 

May want to look at the fuel pump relay, the contacts may have welded themselves and can't release.

 

do you know where that relay may be located?
