As you know from my posts our district has just purchased a propane bus so I don't know what is going on with your bus but, of course, I am interested. Have you spoken with your dealer? Do you have a scan tool to look at codes? I have been told a regular scan tool will read these engines. It hasn't ran out of fuel recently has it? Good luck, and keep us posted please.
