Dan, we did have a fault code that indicated low fuel pressure so at least they knew which direction to start.
Niel, I can get the check engine light to appear by trying to increase the speed of the coach with the cruise control if I press it multiple times. If I want to change the cruise setting now I just turn it off and back on and hit set and I do not get the light. The silver leaf never showed a a fault when this happened. Maybe someone can figure that one out I gave up on it.
