2003 Hyundai Sonata 2.7l ecu location and part number
 

I changed the cam sensor because it threw a code for it, then I have a misfire in cylinders 3 and 6, so I changed the coil pack and now I have no power to those cylinders with the new and old coils, I think I need to replace the ecu but I can’t find any diagrams or anything on where it is located.
