I was having a problem with my battery, well at least i think it was my battery. Sometimes my car would start, and then it just wouldnt. It would start with a jump....so I replaced the battery. Now my after market radio wont work, but the weirdest thing is that my car wont move out of park. I cant get the shifter to move at all, its an automatic. Any suggestions on what the problem is? Any help would be greatly appreciated...
