How to fix a 1991 Honda civic DX hatchback not running found a lose speedometer cable?

My only car, a 1991 Honda civic DX hatchback stopped getting gears. It turns on perfectly, oil is perfect no specs, I found a lose cord, a speedometer cable. Is this why it doesn't get any gears? There's a pin to attach it back in but it blows off when I start it. What can I do? I really don't want to junk it.

Is your ed4 stick?
