Hello everyone, I have a 2004 Jaguar XJ8. I have been driving it about once a week throughout the year since my relocation. I kept a battery tender on it when I wasn't driving it. For a couple of weeks I didn't have the battery tender on it and when I went to start it the battery was done. I tried to jump start it but the car would not start. Well ok, I'll buy a new battery, installed it and the car just wont turn over. It was running fine until the old battery died, after getting the new one with 900cca, I'm getting nothing! It will crank but won't start!! I hooked up the computer to see if I had any codes and the P1000 come up. Where do I go from here??????
