I have a 260 v8 that ran fine, but had vapor lock issues. i put it off to the side for a little over a month and when I turn the key, nothing happens. absolutely nothing. no starter, no solenoid. nothing. Battery is OK because the headlights and wipers will turn on.

What could it be? I never had a problem before!

 

If battery is ok but no click at solenoid, I'd go with the ignition switch. Could be wiring somewhere between the switch and the solenoid too. Original wiring?

 

yes, all original to my knowledge
