I think he's right. I bet you battery is dead. Just enough juice to honk the horn a few times, and light up the interior. I knew my battery was dying because when the fall turned to winter, the colder it got, the air bag light came on, and the speedomater went nuts, and other stuff. Then it finaly just went all at once. We jumped it, it ran for ahalf hour. We turned it back off, tried to start it and it just died... cick click click. Battery totally dead. Bought a new battery, and have had a few months now of perfect starting, no blinking lights, and a smoother idle, all in sub zero weather.
I betcha ANYTHING it your battery. I'd be shocked if it was not.
