Have T 190 that gradually had more and more trouble keeping engine running. Sounded like fuel starvation. Changed fuel filter, drained water from line, re-primed system. Engine tries to start; will not turn over. What next. Thanks; SFPhy

i'd bet its the fuel pickup tube in tank. try filling the tank all the way and see if it helps.
Thanks; filled fuel tank completely full. Drained fuel filter again. It cranks well, good battery, but engine not turn over. Now what. Thanks; SFPhy

For clarity, troubleshooting terms like cranks over indicates that a starter and electrical system is capable of turning the engine over; turns over indicates that there is no physical impediments to the engine turning such as a broken rod or piston seized in a cylinder. Contradictory terms in the same sentence makes it difficult to follow.
Knowing that the engine is sound and acting of fuel starvation issues and the tank is full:
Is the bleed screw on the injector pump fully closed?
Is the fuel shutoff solenoid operating properly?
Is the air filter allowing the engine to breathe properly?
Has the machine been losing power which might indicate a loss of compression?
Does the primer bulb firm up after a few pumps and remain firm?
Hopefully it's something simple; when it tries to start does it fire on a cylinder or two and give a momentary speed up or puff of exhaust smoke or just not give any indication that it wants to run at all?
One other thing...you mentioned draining the water. How much water was involved, as that could shut things down in a hurry. If there is any doubt that water made it to the pump, crack the fuel lines at the injector and verify that diesel is coming out.

That's some good advice. If it has became more difficult to start over time, it very well could be a compression related issue.

Take hose off the inlet side of the primer and stick the hose in a jug of fuel and try it. When it cranks is it smoking? I would also check the fuel shut off make sure it is working and staying in the right position sometimes they get weak and drop when cranking
