For those whose CD player will not play a CD and insists on spitting the CD back out, try this...

• Remove the radio/CD unit. Disconnect the CD player from the radio and take the CD player to a nice clean area as you are going to take some of it apart. Note there are some really good instuctions on how to remove the SVX radio/CD unit if you do a search.
  
• Grab a bunch of cotton swabs and some rubbing alcohol.
  
• As you take the CD player apart, clean all of the solder connctions on the circuit boards with cotton swabs dipped in rubbing alcohol.
  
• Only take the CD player apart enough that you are comfortable putting it back together. Once everything is as clean as new, put the whole thing back together and reinstall into the car.

One of my circuit boards looked like it had some Pepsi spilled on it. I have no idea what this was as I have had the car 10+ years and have never used the cd player as a cupholder. Once I cleaned up the 'Pepsi' and some of the other dirty areas, the CD player returned to working order. This was about a year ago.
