Hi Doug, Bill et al. I have some experience from a similar model 300D, five-cylinder engine of 88 hps. My experience of the feed pump is that once there is air in the fuel system is the car impossible to start. But you could try this: There are several bolts on top of the main fuel filter. Loosen the one that holds the connection from the feed pump. Then act according to Doug´s instructions, pump until no air bubbles can be seen in the fuel, then close the bolt and tighten the hand pump. If the car does not start, you may have air in the high pressure side of the fuel system. What helps is to loosen one or two injectors and running the starter, and having somebody to tighten the injectors when only fuel is coming. Even small holes in the fuel tube system may provide a constant flow of air into the system. Hope this helps
