erjarrett Report post Posted September 3, 2016 Just got back from 800 mile trip and one mile from home the check engine came on. The engine derated and lost power. Engine code read SPN 94, FMI 1 , fuel delivery pressure. Changed fuel filters- did not help. Any ideas or comments, or suggestions. Share this post Link to post Share on other sites
hermanmullins Report post Posted September 4, 2016 erjarrett, Welcome to the Forum. It will help if you can provide the Make, Model and Year of you coach plus the make, model and HP of your engine. With this information you will get responses of folks that have "Been There, Done That and Got the Tee Shirt." Good Luck, Herman Share this post Link to post Share on other sites
