You say that your job stays held in the queue. If it's in the Held  
state, Condor won't try to run it. 'condor_q -hold' will tell you why  
it's held and condor_release will tell Condor to try running it again.

If your job is not in the Held state, check the user log (test0.log)  
to see if Condor has tried executing it. It's possible that Condor is  
repeatedly failing to run it.
