Spray it with some penetrating oil and use an impact if you have one. If not, you should be able to put the car in gear and use a breaker bar and extension to loosen the nut. if your still having issues after trying both of these technics. Use a strap wrench and hold the pulley. Don't worry some times you have to use force to get things apart. That's a stout part. Nothing will break!

The crank pulley bolts are nothing compared to the balancer bolt in the center, wait till you try to crack that one loose.
For the 4 pulley bolts hit em with some penetrating lube and let em soak over night if ya have to. Impact should work fine on the pulley bolts, but I doubt youll get the balancer bolt loose with one, Ive had to use a breaker with a 3' pipe over the handle for more leverage to brake those loose. Last one I did , even the parking brake and transmission in gear wasnt enough to stop the engine from rotating, instead the hole car was moving. So I used a small length of chain with a hook on one end , bolted one end onto where the pulley bolts to then the other end I hooked onto someplace solid in order to keep the engine still, even with the 3' pipe on my breaker it took all I had to get it loose.
Youll need a large breaker bar, and most likely a long helper pipe over to break it loose, and youll have to give it all you got. Penetrating lube wont help ya on the crank bolt, its sheer force for that one.
And mjr is right on. Get a real impact and it will buzz right off of there. I've NEVER had a problem with a crank bolt using a professional level tool. A real impact should provide 500ft-lbs or more in reverse and have several hundred BPM.
Your local rental place may have a decent quality impact (not autozone, a real rental store) that you can rent for a day.
An old school trick if you don't have an impact wrench is to use the torque from the starter. You should use a 6 point socket and a breaker bar with a long handle that won't rotate without hitting something solid, like a frame rail or the ground. Put the socket/BB on the bolt and rotate the handle clockwise until its up against the bottom of the frame rail. Next just tap on the key so the starter engages for a second. DO NOT start the car! Pull the plug wires to be safe. Now check to see if the bolt broke free and remove it the rest of the way with your ratchet.
In case you can't picture how this works - the engine will rotate clockwise pushing the bar in effect in the opposite direction relative to the bolt. That is instead of you holding the pulley in a static position and rotating the bolt with the socket, you are holding the bolt static with the socket and rotating the crank, or screwing off from the 'nut' side rather than the bolt side.
You could have just rented it from autozone, and then got your money back when you were finished with it. I hope the one you ordered came with the installer also.
we have no autozone here but the place they rent the guy told me they only have a puller. so I told him about the installer and he had no clue so I bought one who knows maybe I'll help some poor bastard one day
