Does a 1998 3.3l pcm require programming with vin if part number is correct?

What is your question?

Van will start and run perfectly sometimes. Sometimes will start and run for a few seconds, then shut down. Sometimes will not start and sometimes will not crank at all. Am looking at replacing pcm with used module. Do not want spend $300 having dealer reprogram.

What makes this problem better or worse?

random
