there is a little black box on the left inner fender just in front of the air box that has I think 4 connectors. Remove the cover. (it just snaps on) The one on the front has a gray top with a wire that comes out of it and goes back into it. Sort of looks like a jumper wire. The same thing happend to my 1987 Maxima and all it was, is the wire on that connector was burned into and it wasn't getting any power to the interior lights or dash lights. Once I fixed the problem, my interior lights and dash lights began working. As far as the starter problem goes, check your relays in the box in front of the battery. I believe it has a starter relay in it and it could have gone bad causing the starter not to work.
