There is one behind the harmonicbalancer and crank pulley. There is also one on the backside lower center part of the engine that has a cover so you would miss it if you didn't know it was there. This is on the 3.8l. Hopes this helps.
That year model did not use are have a crank sensor.
The crank sensor is located on the rear of the engine,on the right hand side about 5 inches from the oil pan.

There is not a camshaft sensor on the '93 3.1 Lumina, just a crank sensor on the back side of the engine between the block and the barrel of the transaxle. Easy enough to get to from underneath the car.
Simple description: The crank sensor sends information to the ECM so that it knows when to fire the plugs. It is located behind the harmonic balancer. It requires removing the balancer in order to remove and replace it.
I have a 92 lumina with a 3.1 and I found the crank sensor to be located on the passenger side of the engine in the back of the engine NOT on the side of the engine below the knock sensor. Hello, in my experience, all O2 sensors are located in the exhaust just after the manifold. It appears easy enough to change. If it is the crank position sensor you are looking for, take a look around the main pulley at the bottom of the engine, you may see a square-ish component located close to the actual pulley wheel, this would be the crank position sensor, it should have wires connected to it.
