Wow, that's getting to be an "oldie"! Does this car have a factory alarm/anti theft? The flashing headlights seems to indicate that. And in your workings with it may have activated it. Try a complete battery disconnect for a few hours (some call a hard reset) and then try it....Good Luck!

I would agree that it sounds like an alarm issue, but it might be an aftermarket.

If a factory alarm it can be shut off by turning either door to unlock with the key.

If that doesn't work, look under the dash for a box with aftermarket wiring. It will have a inline fuse holder on the wiring. Remove that fuse.

Now look at the wires. Two of the wires coming from the black box will be spliced into a wire coming from the factory ignition switch ( lower part of the steering column.)
Disconect the aftermarket wires from the factory wires and splice the factory wires back together. Your car will now start.
