What I'd like to do is offer you $500 for your vehicle and then once you hand me the keys and the title take the two minutes it's gonna take to make this fix for you and then drive it home but that's not gonna happen because you sound kind of determined to get this thing fixed so here's what you need to do.
Go to the positive battery terminal where all those plastic connections are right by the positive cable you'll notice that one of the connections that has a thick gauge wire (not as big as the battery cable) I don't know it's a thick wire but not too thick that wire is going to be crusty and crunchy inside it's plastic housing. what's happening to your vehicle is that your engineControl unit is not getting 12v power so clean those connections really really good and then your pathfinder will be right back in business.
