‘11 parasitic battery drain Constant fuel pump priming, start button light on

*****UPDATED PLEASE READ POST 17 for fuel pump update etc *****

Hello just bought the car a week or so again have had the increased battery discharge a couple times when starting the car. Last night I noticed the start/stop button light does not goes off. Not after 16 minutes not after 6hours. From my research it seems the CAS module controls the start button? I do NOT HAVE CA I don’t know where to go or what to replace at this point. I’m really on the fence about selling the car from all I’ve read with all their electronics they seem highly unreliable long term. I do enjoy driving the car but am not looking for a money/time pit. I’ve read things from headunit replacement to IBS but not a lot surround my exact issue. I do have the IBS unhooked right now.. it made no difference
