Thanks Steve. I found your write-up on "Evaluating Electronic Engine Controls" on this site. I'm going to give that a try this weekend. I'll let you how it goes. By-the-way, I know by reading my forum that it looks like I'm just a "Parts Replacer",but it's just that I don't have access to any trouble shooting tools. I do although have a book on the basic CIS fuel injection systems.
Thanks again, Greg
