Engine Will Crank But Not Start Due to Fuel Return Line Leak on Dodge Ram 3500

If the engine is difficult to start or cranks but does not start, it can be caused by a leak in the return side of the fuel system. This type of leak can allow air to enter the injection pump resulting in starting issues. A rubber hose on the back of the injection pump, connecting the pump to the steel hard line, that can be the source of this type of leak.
