Problem overview

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.
