Hi ignats12. Welcome back to the forum. With so many things affected, suspect a problem with the Body Computer. It lives to the right of the glove box. One word of warning tough. You MUST find a used one from a car that does not have the factory anti-theft system if that is not on your car. If either the Body Computer or the Engine Computer are installed with that programming, it will teach it to the other one which will self-program itself for that system. That programming can not be undone. At that point BOTH computers will have to be replaced before the engine will start.
If your car does have the factory anti-theft system, any Body Computer from a similar car can be used because it will learn the system from the Engine Computer as soon as the ignition switch is turned on. From that point on though, it can only be used on another car with the anti-theft system.
