Got my Pathfinder used, and it has been running like a champ since I took over. Just about a month ago, I got a new stereo to replace the OEM one. Then added subs and an amp.
The battery is fine - and it won't even start with w jump?
Any ideas? All the fuses look good. I have had cars that the battery said it was okay but then all problems solves with a new one anyway. Should I just start with that?
What else...?
