We have a 2009 bluebird vision with 6.7 cummins, allison trans , wabco brakes. The problem is a crank no start intermitently i have changed fuel filters run a leak test with jpro it has no codes need help
Had one recently that was letting air into the fuel system because of a poor primary fuel filter installation. Remove the spin on engine fuel filter and see if it is full, if not fill and re prime fuel system and check for other leaks.
