If, when you look at the engine from the front (of the engine) it rotates clockwise (most engines do) you can install a socket on a long breaker bar, to the crank bolt, lean the bar against the ground, reach in the car and bump the ignition key once and only momentarily, this should pop the crank pulley bolt loose.
