Welcome to DF
The air injection pump or as you call smog, is shorted will cause a 12 volt draw.The only to fix this problem is to replace the pump. It takes about 45 mins to do the job. I will send you a pm with the part number.

 

Oh thanks man I just read this after I mailed you bac but I still had some questions for you if its not to much of a bother
