Ok It is an Auto Trans . Glow Plugs working. I verified this with a visual with injectors out and before that checking amperage draw on each one.

I am getting fuel to all injectors. As I found out when I bled them. The injectors are not opening when cranking with a good battery. I tested this by hooking up an injector to an injector line outside of the cyl head and cranked it.

The injection pump is not supplying enough volume or pressure to the injectors.

I am asking if anyone knows how (or where to find out how) the fuel supply works inside of the injection pump. I will ask a few Mercedes Techs tomorrow and if I do not find out I will get a used one and dissassemble it and figure it out.

Thanks,Dave
