Hi all, I was driving my 1992 f 150 today and it just went dead. pushing in and letting out on the clutch it started running again and then dead again. I smelled a burning wire smell seemingly coming from under the dash. Nothing is apparent under the hood and I cannot find any burnt wires under the dash. I even tried a new ignition switch and no help. All electronics work, accessory lights and all come on and it is turning over really good but wont start. Any ideas?
