If the pusher bolt is out the pressure should be off and you should be able to work the puller out with a pair of pliers, of other creative means, I'm amazed it even fit around the bolt (most don't).

If that fails you can have a shot remove the entire BB by removing the other crank, and the cup behind this crank and taking it out with the spindle attached. Give it a shot trying with the pliers or another way, but don't go crazy and make it worse. A decent, experienced mechanic might be able to get the puller out even if you can't, and that would be the best solution.

The other option if the left crank is the issue is to use an abrasive cut-off disc and cut the spindle behind the crank arm giving access to the BB so it can be removed the normal way. If you don't have the tool, but have a decent relationship with an auto mechanic, he can do this for you.
