I recently picked up a 98 XJ Sport that had been sitting for about a year (4.0, auto). The battery was dead and we jumped it to get it started (I drove it around). I trailered it home, I tried to jumpstart it again and now it won't start. I put a good battery in it and it still won't do anything. The key turns over but I am getting noting from it. After turning the key, I can get the accessories to work. I have tried putting the tranny in neutral and it still won't start. I pulled the starter and it had it tested and it is woeking fine. Any idea????
