Do you have to remove the harmonic balance to gain access to the crankshaft sensor? Someone is telling me no, but I can't see any other way. There is also what appears to be a hard plastic shield that I can't see any other way of removing to uncover the sensor accept by removing gaining access to the H/balance, then removing the shield, then you have access to the sensor. Am I wrong? HELP!

I think this makes more sense on my second sentence.

There is also what appears to be a hard plastic shield that I can't see any other way of removing (to uncover the sensor) accept by removing the H/balance, then removing the shield, then you have access to the sensor.

Dear John T: I have a '92 Buick Park Ave with a bad crank sensor, also! Yes, you have to remove the crank damper and the shield. Just pry it off and push it back on when ready. That's the easy part. While you're at it, examine the inner and outer interupter rings carefully! On my interupter assembly the whole thing was warped and chewed up the sensor and magnets! If the rings are damaged, replace the damper. There is a tool and a procedure for correct installation. Find and follow them to the letter.

"just pry it off"
that is funny!
I found this very hard to take off and I have taken off MANY pulleys. Two tips: the proper puller for the application & use two pry bars that, if a line was drawn connecting where they touch the pulley, the line would intersect the exact middle of the pulley.

I replaced the cam magnet and sensor now the engine is extremely hard to start when cold. After it starts, it runs very well. Could this be the crank position sensor? IF so, how do I adjust this? I don't believe it is hitting the interrupter rings but it didn't do this before I changed the cam sensor.

Where is the crank shaft position sensor located? Do I need any special tools to change it?

I have a 92 buick lesabre 3800 motor. It starts and will run but after a while it will die and will not restart for about ten minutes. I replaced the coil pack and it continues to do the same. Could it be the crank position sensor or the cam shaft sensor ?

Ignition control modules are also a common problem. No spark and car will not start. Most common is after driving parking the car and then trying to start it in a little bit and it won't start. The module uses the inputs from the crank and cam sensors to control spark. You can test your crank and cam sensor outputs right at the ICM connector which is easier than trying to test at the sensors themselves.
