  I'd check the basics, are you sure you have enough power to the stamp and the pink, are your grounds tided together? make sure you pink is set to 2400 baud (or whatever your code is set to) double check that you are connecting to the right pins on the Pink, for TX and RX, try a different stamp if possible. My bet is that it's a baud rate issue.

  Can you attach the exact piece of code you’re using? There are versions for each BASIC Stamp model. Also, are you doing this from a cold start? The PINK should be powered on for >5 seconds before attempting communication with it.

  Here is the code I'm using. I'm am waiting at least 5 secs before attempting to communicate.
  

  TestBytes       DATA    $09, $55, $AA, $FF
  
  Main:
    DEBUG "Testing communication with PINK Module..."
    verify = 1
    FOR index = 0 TO 3                     ' Four Bytes
       SEROUT TX, Baud, [noparse][[/noparse]"!NB0RSI"]
       SERIN RX, Baud, [noparse][[/noparse]STR serStr\16\CLS]
       READ TestBytes + index, nbvar       ' Fetch Next Test Byte
       SEROUT TX, Baud, [noparse][[/noparse]"!NB0W00:", nbvar, CLS] ' Send To PINK GP 00
       SEROUT TX, Baud, [noparse][[/noparse]"!NB0R00"]              ' Send Command To Read Variable
       SERIN  RX, Baud, 2000, Timeout, [noparse][[/noparse]verify]  ' Get One Byte With Timeout
       IF verify <> nbvar THEN Failure     ' Check For Match
    NEXT
    DEBUG "PASSED!"
    END
  
  Failure:
    DEBUG "FAILED!"
    END
  
  Timeout:
    DEBUG "Failed!", CR, "Communication Timeout!"' Serial Timeout
    END

  Hey everyone,
  I got it to work. The problem was that the ground wire was faulty.
  I replaced it and everything worked fine. Only took me a whole
  day to figure that one out. [noparse]:([/noparse]
  
  Thanks anyway.

  Great! you did better than I did! I had my pink disabled in about 5 minutes of getting it. had to send it back to parallax to be fixed. but hey now I can read the manual and say hey! that warning is in there because of me!
  
  Glad to hear it's up and running! they are a lot of fun!
