Holy run-on sentence Batman! Please use punctuations man, I can hardly understand what you wrote. Not being a d***, just want to help.

Did you replace bcs with the battery plugged it? I would also check for boost leak.

 

Yes the battery was plugged up still, I didn't take anything off except my bcs and the oem one back on the same way.
