I have a B8200 with a D950 Diesel and just did a valve job. Now I can't get any fuel to the injection pump. This is my first diesel so I need a little advance. I fund that this D950 has a Lift pump and I can't get any fuel pass it. I also heard that they can leak fuel into the crankcase. Is there any easy way to check if the lift pump is pumping fuel correctly and If it might leak into the crankcase. I'm also going to check to see if the stop lever is operating correctly. Is there anything else to check?
