89 Grand Prix...Crank Position Sensor

I'm having a problem with a friend's Pontiac. It won't start due to it not getting spark. I replaced the original ignition module with no luck. I tried to remove the Crank Position Sensor and it broke off. I assume the only way to get it out now is to remove the oil pan. However, this process seems to be a nightmare! Any one have any insight on the proper way to do this? Thanks for any and all your help!
