The are many things that can cause your "check engine" light to stay on. One possibility is that although you have fixed the trouble code for your crankshaft position sensor, the code has not been erased from the computer's memory. Another possibility is that you have another issue going on that is causing a new trouble code to come up. You're going to need to have your car hooked up to a ODB-2 engine code reader to see what the issue is. These code readers are available for purchase at any auto parts store. In addition, many of your local auto parts stores will check trouble codes as a free service to customer. If not, many parts retailers offer the option to rent one of these code readers. Which ever way you decide to go, run a full engine/emissions trouble code check. If the only code that comes up is the code that came up previous to fixing your positioning sensor, then all you need to do is erase the trouble code from the computer's memory. (Most code readers have the option to erase trouble codes, but if you're going to rent or buy one, I would suggest that you check to make sure that the code reader that you're getting is capable of erasing trouble codes as some code readers only indicate the codes and will not remove them from your computer's memory.) If your trouble code scan reveals other codes, then you'll have to fix and erase them as they arise.
FYI- In my experience, I've noticed that 95% of the time that a check engine light/trouble code arises that it is usually an emissions problem (oxygen sensors, mass air-flow units, MAP sensors, etc.). However, General Motors products are notorious for getting trouble codes for having loose battery/ground connections and for having worn-out fuel caps. With any GM vehicle, I always check these two things first to try to save me from having to look further than I need to.
Hope this helps! I'm sure once you've scanned your cars computer and erased any existing trouble codes, that you'll stop being annoyed by your check engine light, as I know how bothersome it can be. Have a great day!

If i remember correctly the entire rear light assembly must be remove in order to access these bulbs. This is true if the license plate is on the trunk. If this is the case then there are nuts on the inside of the trunk that must be removed.

THE POWER STEERING PUMP PULLEY --- ARRGGH...Not a problem.
The power steering pump is held by two bolts. Use a socket and remove the top bolt and loosen the bottom bolt. Be careful not to completely remove the bottom bolt. The PS pump will loosen up enough so that you can push it towards the firewall and you will JUST have enough room to remove the waterpump bolts. Its tight but it will squeeze out.

This is a fairly common problem, Gm has actually issued a service bulletin regarding this repair. The problem probably originates from one of your wheel speed sensors that is mounted inside one of your front wheel bearings. To be sure, you need to have the car scanned to find out which one and then you have to replace the whole bearing assembly because the sensor is integral to the bearing. The bearing is not hard to do but you will need some professional tools if you want to do it yourself. At a shop it should cost between 3 and 400 dollars complete.
