no start - need troubleshooting help

Hi folks.

I restored a '68 Barracuda 12 years ago. Since then, I've just been enjoying it as a weekend cruiser. It has a 340, with electronic ignition (orange box) and an Edelbrock carb.

It's been reliable as hell until this last weekend - it had been parked for a month, and will not start. It turned over, and I have gas at the carb, but no indication it is ready to start.

Is there a troubleshooting process around I can work from? Thanks!
