My 04 250 diesel will not cold start, it blows black smoke and then dies and I turn it over so much that the batt. dies when I do get it started it spits and sputters while blowing black smoke. Once it it warms up run like its summer time, good spped, take off and good power. Summer and spring two cranks starts rite up. Any ideas

The black smoke is unburnt diesel fuel- lift your foot. When I was learning to drive diesel trucks (many years ago, in one of these trucks) I was taught that when going up hill under load, I should lift off the accelerator until it just starts to die off, then give it a little bit just to hold revs. No more black smoke.
When you start it, do you let the glow plugs heat for long enough? (Does it have them? I can't remember).
Not knowing your experience with diesel motors,if the glow plugs are not being allowed to cycle it makes starting the motor cold much harder. If it has a block heater package that also helps to plug in. Keeps the coolant warm and in turn keeps the motor warm.
Sounds like not all the glow plugs are working.It should run fairly smooth on a cold start if all of the glow plugs are working..Also you shouldn't drive off on a cold start with a diesel,Its really hard on the motors..At least give them 10 to 15 min on a cold start..The oil in them is a really thick oil and when there drove on a cold start theres no oil lubricating the internal parts and will cause the motor to seize up..You may already no this and dont mean you drive it as soon as you start it i just wanted to let you know..When you get alot of white smoke it could be two things,Theres water in the fuel which will make it not have much power die and smoke..But if it runs fine when its warm theres some bad glow plugs...Hope this helps you and have a great day
65 thousand isn't much for a diesel engine. I would not be too worried if it is only when you first start it up.
Diesel smells like oil at the best of times especially when it gets on your hands :) I have an old diesel engine (280,000 km never had the head off ) with no fancy turbo or anything on it. It used to blow a cloud of black smoke when I started it in winter time. It used to crank more before it started when it was cold too. The problem turned out to be 5 out of 6 of my glow plugs were broken. So it was just squirting more and more diesel into the cylinder before it generated enough heat to start. When it finally kicked all the fuel burnt at once hence the black smoke. There is a way to test your glow plugs (assuming you engine has them) with a multi meter. Or just get a mechanic to check and replace them as needed. Mine were about as complicated as changing a spark plug.
This is just my experience. I'm sure there are other reasons your can might be blowing black smoke.
I don't drive a Ford but I drive an International and white smoke on start up means the engine is too cold to properly burn the fuel. Your black oil or soot is unburnt fuel. You should look at your engine's preheat system for a malfunction.
Ones the diesel engine gets weak its thn a hard start!, becausea diesel engine mainly fires up on good compression, i guess its time for an engine overhaul .
Black smoke is produced when too much fuel is injected into the cyl. There could be several issues here, but I would start with running a diagnostic on your O2 sensors and MAS/MAP sensors.
