I am having problems with my 1990 MJ.A couple of days ago i stopped at a gas station and set the emegency brake and it died.When i tried to start it i had nothing.I opened the hood and had a burnt electrical smell from around the starter relay.I replaced that.Checked all the fuses and relay's they are good.So i replaced the ignition switch still nothing.Anything the key operates does not work.Radio,cig lighter,dash lights,and starting.Could you give me any idea's.1990 MJ 5 speed,two wheel drive,4.0.Lost don,t know where to go next :???: !!!
