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
