No Fire!

This is known as "throwing parts at a problem." In your case you suggested the most expensive part in the ignition system first.

Why don't we do some troubleshooting FIRST?

lol yes you are right. i dont like the throwing parts at it advice either, but i figured in this case , it may be a matter of just plugging in a new box. some people keep a few these laying around. that was all i had to offer since we dont know what ignition he is running.
