The most obvious things to check, which you probably have already done:
- Is the script's executable bit set?
- Does it work if you start it manually?

Provided the answer to both questions is "yes", my brute-force approach
would be to print logging messages to a file - for example by using echo
- or to the console - for example by using echo or the log_* functions
/lib/lsb/init-functions provides.
Even mor brute force - but useful if nothing else helps - would be
setting the shebang to
#!/bin/sh -x
which prints each statement before it gets executed.

One more thing: you don't use some bashisms in your script while the
shebang points to /bin/sh? /bin/sh since Hardy (IIRC) is dash not bash.
