Troubleshooting an application that won't start

Troubleshooting an application that won't start

(Sorry for the barrage of questions)

No particular application, just looking for method:

If  I'm trying to start an application from the command line and it doesn't
start, what's the best way to troubleshoot the failure?
I'd check the syslog output and any application log if one exists.

Trying to launch the application using truss logs system calls made to a
file before it dies, but the output is far to cryptic for me to understand.
Are there more straightforward actions that should be taken first? (or a
good resource to help me understand the truss output?)

Also, a badly terminating process may create a corefile. I've manually
created corefiles using gcore but never managed to successfully use the
process information commands to examine them. If anyone can suggest a good
study/tutorial on using these commands, I'd appreciate it.

Any other suggestions would be greatly appreciated.
