So wife driving along car just shuts down, pulls over, won't start. Towed home. (FIY 6 month ago replaced bad starter, so its new, so is battery, great power, headlines bright, and voltage, 12.6 volts(. I open door, dash door-ajar light comes on, turn KEY to ON position, no bulb check lights come-on, START position nothing also. Power locks and other things that work "independent" of key in ignition work. So Key Turn does nothing, and also died while-driving. Never happened before even intermittently. So ELectrical Ignition / RUN circuit seem most likely? ECM RElay? Ignition switch? only two, I can think of. "Jiggling key while turning", in ON or START position does nothing. Ideas??
