Others have tried this, and the puller generally bends/breaks before the cog moves. This is a fairly common problem with these cars; it's the result of a botched crank-nose repair. Liquid metal used to fill a worn key-way bonds the cog to the crank if it's installed before everything cures.

I believe older Miatas had threaded holes in their crank gears for this very purpose. Mine does not. I only found one hole and it wasn't threaded; I think someone else may have drilled it in an attempt similar to mine.

You could also take a dremel and cut a slice down one side then split it with a chisel and hammer. Good luck!

I tried most of what you posted.
I ordered a 4-inch angle grinder with some cutting wheels. Here's hoping I don't damage the crank in the process of cutting the gear...
