Question type: Maintenance & Repair

1992 Oldsmobile 88 Royale 6 cyl 3.8 it will start on it's own before 12 hours of
sitting but 12 hours or after It needs a jump to start. It's not the battery,
alternator, starter or solenoid they have all been checked by Auto Zone & they
say there's nothing wrong with them, so please tell me what it might possibly
be.

Sounds like there is a parasitic draw on the battery. May want to take it in to a shop to be checked or here is a video on how to check for this... www.youtube.com/watch?v=QRso1A0VScw
