Clean the area well, then remove the SCV's and check the O-rings on them for splits. IF you have any blanking nuts or can make one, you could blank one of the feeds at the common rail and see if it will start on one HP pump- if not, try the other.

Have someone press or wiggle the connections at M.... the control valves, while cranking the engine, have seen poor connections there cause the same symptoms

Blow back into the tank with compressed air. Then try again
