Why isn't the spark causing the pilot to start?

There is definitely a spark. When I use the lighter, the flame goes right across where the coils for the spark are. The flame color is blue, I can take a picture if it helps.

Ok, let's try this a different way.

Is it a gas LOGSET?
Is it a GAS FIREPLACE INSERT?
Is it a GAS FIRE PLACE?

Can you take a pic that shows the ENTIRE unit?
 
Ok. I'm gonna go out on a limb & say that you have what is known as a Vent-free or household vented fireplace.
On the back side of the horizontal pilot burner (where the pilot flame actually comes out) there is a small hole, maybe 1/16" to 3/32" in diameter.
This is the ODS (Oxygen Depletion Sensor). Check to see if it is plugged with dust or lint.
You can try blowing it out with compressed air. It is a common symptom for that type of unit.
If that doesn't work, you will probably have to replace the ENTIRE pilot assembly (your first pic)

What's happening is if I hold the pilot, I can hear and smell the gas coming out. While holding I hit the spark. I see the spark, still hear the gas, but no pilot light comes on. If I don't use the spark, but use the lighter, everything works. With that context, could it still be the O sensor?
 
Does the pilot stay lit when you use the lighter & release the pilot knob?
Is the spark actually IN the gas flow from the pilot burner?

The pilot stays lit when I use the lighter, it is a blue color. Once the pilot is lit, everything works as expected. It stays lit and I can turn the fireplace on and off. Through visual inspection, the spark is in the way of the gas. When I use the lighter, it sits inside the pilot flame.
 


Is it possible he needs to clean up the ignitor and contact surfaces? Maybe some corrosion is causing a weak spark.
