64 dodge dart GT wont start/crank

Thanks for the help! When I got to the car, with my trusty screw driver, and started tracing thing back from the battery, I noticed a wire with a rubber "Thingy" that plugged into a box in the fire wall looked loose. One push poppies into place and WA-LA! Car started! ;). My son thinks I'm a genius! Don't tell him any different!

I sure appreciate all the input that came so quickly! Great resources here.
