Okay I've got a 90 yj with a 4.2 in it bee. Having problems with it but slowly trying to fix it now I've hit a dead end. While driving down the road the other day it just died. I don't now why but it just did. Now that I've got it back home. Head lights come on. But when I turn the key nothing. No radio not starter just nothing like I wasn't even turning the key. Not even the buzzer goes off when I turn the key. So I'm lose on where to start.
