I have a 97 wrangler 6 cylinder. Parked it one day and came out the next and it won't start. It has a full tank of fuel but the fuel gage reads empty (Its always worked. Ive checked fuel pump, relays, fuses. Im stumped. It cranks easily. The fuel pump relay does not engage when the ignition is on. Ive verified its a good relay. Im thinking its either the ignition switch itself or the darn computer. Anyone have any insight ?
