Question about 1997 Pontiac Bonneville
In order to remove the damper you need to put the car on jackstands, remove the right wheel & inner fender splash shield, the drive belt and the lower bellhouseing cover plate stick a flat head screw driver in the teeth so you can loosen the crank nut.
I would NEVER tell you to use a six point socket on a breaker bar wedged so that when you "bump" the engine it will unscrew the crank bolt. Don't ever do this cuz it's dangerous, nope dont do that, no, never.....
Hope this helps.

SOURCE: Crankshaft Position Sensor
The crank sensor is on the front of your engine behind the harmonic balancer. You will need a balancer puller for a 3.8 and a crank sensor alignment tool to do this lob.

SOURCE: broke crankshaft position sensor
If you can get a magnet....use it to pull it out...has to be a stong one....like on the back of a audio speaker. That's the part that's stuck right? Is there any part of it sticking out?

SOURCE: locating the crankshaft sensor
The crankshaft sensor is a sensor that is on the front of the motor. If you look at the front of the motor look around the bottom pully there should be a sensor behind that pully.

There is a special tool for pulley removal. it is called a harmonic balancer puller. it bolts onto the balancer and has a screw in ram in the center. Sometimes it helps to install the center bolt part way into the crankshaft but do not use the washer. If you use this tool, sometimes the use of an air gun or electric impact wrench may be necessary especilally if the balancer is stuck from rust.Since you said you used a puller, I hope it was one as I described otherwise you can and will destroy the pulley. In extreme cases, you can use a small sledge hammer and after tightening the ram bolt, give one sharp tap on the end of the ram.Do not pound repeatedly on it or you can hurt the thrust bearing on the crank.

the code you have is for a misfire on #3 cylinder. (im sure you knew this right?). the crankshaft position sensor will not cause one individual cylinder to misfire. what i typicaly do in this scenario is switch the ignition wire off of the guilty cylinder onto a known good firing cylinder and see if misfire moves to the other cylinder. i repeat this process by switching the spark plug and finaly the fuel injector. a compression check may be in order as well (but not a likely cause) unless you have access to a tech 2 (gms diag computer) you will need to clear this code after each component is moved and see if you get a new code ie :p0304 if switched to #4 cylinder..other wise if you do have access to a computer that has a misfire chart in its features you can quickly identify the guilty component. as i side note the ignition coil may also be faulty, but i believe your vehicle has a 3.8liter meaning that it has a coil pack....switch the others i listed and see ow you make out....good luck!
