code b2A20-30, Ignition stuck in start?

I have an auto repair shop in Port Huron Michigan. I currently have the car listed above at my place, it has been to several shops for the same issues, and no one can seem to resolve it. Getting a trouble code b2A20-30 ignition stuck in start I cannot find any information on that code in my scan tool as far as possible causes or on my Mitchell one software. The vehicle is having trouble starting at times sometimes the key will just turn forward and not do anything as if the battery was disconnected or the ignition switch was bad which I have replaced the ignition switch already. The radio will turn off at times and the display where the odometer is will blink on and off while a chime sounds as well. I have recently discovered that if I put the key in the ignition and leave the key forward until I hear a chime approximately 45 seconds later it will start every time, I don't know if that's helpful or not. Also, the shifter doesn't want to go out of park at times. Also, I noticed while checking all the fuses there's a 5 amp radio fuse in the passenger compartment fuse box that would be used position number 28 and for some reason when I touch that fuse with my test light to check it, it clicks and the instrument cluster makes a chime sound every time I touch that with my test light, not sure if that helps either. But that's what I found out so far and that's all I know. I sure would appreciate some help with this one. oh, one more thing, the computer has been replaced in this vehicle already as well by a previous shop. Thank you so much.
