I feel your pain Globerg, i had excactly the same delima.
Wedge it out is about all you can do, i didnt hurt the oil pump housing but i did destry the timing pulley and the front oil seal.
Real pain in the ass.
If i had my time again i was be using MAP gas and heating that shit up, it should pull off fairly easy once you start to work it loose.
Just make sure you heat he pulley evenly on all sides.
