So I just got done rebuild and reinstalling my engine in my 04 rx8 automatic and now when every the Battery is connected the car alarm goes off. So when I got the car the key fob never worked even after I put a new battery in it. so i alway used the key to get in and start the car. But now the car alway is always going off. And the car will crank but not start. I have tried putting the car into programming mode but that didn’t work. I have no idea what can cause this and I’m going here for help.
