I have a 2007 blue bird vision with a cat c7 acert in it and when it starts once its cold it will miss and carry on like it has lost its fuel prime. I have no check engine light, tried a different heui pump, timing position sensers, and even have put a clear line inbetween the fuel filter and cylinder head and ran engine then shut down overnight and i seen no air getting into the sytem. I have also replaced the fuel pressure regulator valve at the rear of the cylinder head. Nothing i do makes the issue get better or worse. Has anyone else had this issue?
