It's down behind the starter.
It is located on the distributor under the cap and rotor Crank sensor should be on the front bottom of engine by the crank pulley
on a 1994 it's behind the harmonic balancer
the crank sensor is behind the harmonic balancer
The harmonic balancer must be removed to change the sensor because the crank position triggering rings on the back of the balancer are entwined with the pick-up, Sorry
yes
Does the LSS have a 3.8L engine? If so, the crank sensor is behind the crank pulley/harmonic damper.
by the harmonic balancer
You have to drop the starter on the front bottom driver side of the engine... next to the transmission. The crank sensor is about in the middle of the block. One bolt holds it in.
Took me about an hour to change mine, but it was the first time.
To replace the crank sensor you have to remove the harmonic balance taking special attention not to damage the pulley or the cam shaft. Remove the two 10mm retaining screws
Do you mean the Crank Position Sensor (also called a CKP)? On 3.5L it is on the side of the block between the firewall and engine (backside if you are looking from the front of the engine). You can get to it from under the car by first loosening the starter from the transmission and dropping it out of the way. The sensor is held on by a single small bolt that you can get at with a flat wrench. I don't know if the 3.8L is similar. The 3.8 wasn't used after the 1999 model year.
If your 3.5 engine is the same as that in a 2001 Olds Aurora, go to www.autorepair.about.com and search on "2001 aurora 3.5 crank sensor". One of the hits will be a diagram of where the crank sensor is located (above the starter motor). Note that for this engine, a "relearn" mjust be done after replacing the sensor. There is a link to the procedure for removing/installing the sensor and for doing the "relearn". Hope this helps
