Doubtful, headlights don't work through the ignition switch, they're hot at all times.
How did you test the fusible link?
Does your horn work? That circuit is independent of the fusible link.

I tested fusible link w/ ohm meter checkin resitatance. It didn't show as open/faulty. This truck is missing horn button wiring on steerin wheel so don't know if horn works or not. I figured ignition switch bad because when turned it to crank i got nothing.

Tug on the fusible link, see if it feels "soft" or stretches, if yes, it's bad and needs to be replaced.
With the link burned out, there won't be any power to the starter solenoid either.
