Thinking about pursuing a career in pharmacy. Need advice?

ANY major works and you don't need a minor. I suggest you keep the engineering major and complete the classes you need for pharmacy school. If your PCAT score doesn't come out to be too good, engineering can be your backup. If you switch to chemistry, you might need to take more classes for the major itself. Getting a minor, especially in psychology, won't help get all the classes finished in time for pharmacy school. Also, why psychology? Biology would be a better minor. But engineering makes you a little unique.
