So replacing the fuse got me up and running. Now I'm not sure how that explains the intermittent no crank, no start. I drove it to church this morning with no cranking issues. After church, no problem still. When I got home, I shut it down and attempted to crank again and nothing. This is the problem I've been dealing with for a while. If the fuse is the problem, it wouldn't crank at all. Right?

I believe you have two problems.
1) If the fuse was making bad contact in the fuse panel you could have an intermittent no crank because
the starter relay would not energize. If the fuse was blown it could have been when you messed with the relay.
2) If the Security light is coming on that would indicate the key pellet wasn't read properly.
That could be a bad ignition key cylinder (a pair of stranded wires go bad. The wires twist every time you rotate the ignition key cylinder. This causes the CCM to read the wrong key pellet value.
Most people don't replace a bad key cylinder because you need to get into the steering column.
To bypass a bad ignition key cylinder that fails to read the key pellet properly.
At the base of he steering column you disconnect the small two pin usually an Orange and White wire connector.
Place a resistor across the male connector going back to the CCM. The value of the resistor is the same value as your key pellet.
This is a Bubba fix and allows a car thief to break the ignition key cylinder and use a screw driver to
start the car.
The CCM could also be marginal where it doesn't ground the relay. You can leave the Yellow/Black wire
permanently grounded. I believe some 92 and 93 CCM's did have intermittent problems grounding the starter enable relay. Permanently grounding the Yellow/Black wire will eliminate that problem.
Here's a picture of the key cylinder.
