1992 Chevy Lumina 3.1 engine- Crank sensor, where?

I am having problems locating the Crank Position Sensor (CPK)..???Any help on this would be greatlt appreciated- Thanks!

the crank sensor is above the engine oil on the firewall side. it is a real pain to get at. if you remove the right wheel and transaxle supporting bracket you can get a direct view of it. make sure about the bracket bolts are not supporting the engine aswell. some gm model were designed that way. you might have to support the engine.
