I will look and find that ecm number. It starts with 12. I remember that much of it, or I think so. Anyhow, I will get it and THANK YOU very much!

A big and grateful THANKS TO ALL!!! If we had all of this help before. We would have had this baby running over a year ago. Thanks again to all for all of the help, tips and advice. We will try it 1 at a time and get this thing fired up again.
