Disconnect the battery again and leave it disconnected for fifteen minutes or longer and reconnect and see if the car now starts and runs. After tat I would say you have to hook up a scan tool to see what codes are stored in the computer. I just worked on a Mazda similar story, owner replaced alternator, caused a short and it damaged the computer in the car ended up being an expensive repair. There are companies that re-manufacture your computer if it has been damaged.
