Last time I had an issue with a crystal....it turned out the cut. The OP stated he could drive a clock in with a generator...wonder if he changed the config bits for that as well? If not....I wonder if thats still the issue. Also the config bits for the freq range needs to be correct (having done that as well once). Maybe he could post the config bits?
