With your crank socket, turn the engine so #1 is not at TDC, take out the plug and stuff in some nylon rope. I use some old 1/4" stuff I have lying around.So I started this "simple" task with the intention of replacing the water pump in my formerly abused '79 Sports sedan. No, no, the crank pulley must be removed first...so taking tips from you good people, I attempted all of the pulley removal methods save one...jamming the flywheel teeth with a cold chisel and using a whammy bar to turn the big bolt on the pulley. But wait, first the starter must be removed to expose the flywheel, and there I stalled out. I have successfully removed two of the three starter bolts, but the top-most bolt has almost no access from behind to hold the nut still. So here I sit, nothing but tears and grease. Considering pulling the solenoid off of the top of the starter to gain access but can't hold that nut still either. Sympathy cards accepted...
Turn the engine with the crank socket until it locks up and using a long bar carefully apply pressure until crank pulley nut comes undone. Remove nut and pully should slide right off crank.
