Default 1986 ford f250 6.9 diesel cranks but won't start

Ok guys I did a trans fluid and filter change about 2 months ago but I did not get anoufe trans fluid so I parked it haven't had time to mess with the truck till now. So when I go to start it it cranks but won't fire before I parked it I ran it dry of fuel so it wouldst be sitting in the tank. Ok so I put some fuel in the tank it's getting fuel to the filter. And when it's cranking there is a blue white smoke. Thanks guys sorry for the long post

What's the temp outside? Is it cold and are your GP working, all of them? The white smoke is raw fuel and the blue could be fuel and or oil trying to burn off from sitting and not firing and sealing up. Don't use ether, but you could give it a small blast of wd-40 down the intake and see if it fires that way. WD is flammable, but it lubricates a bit, so it better that ether.

. I'm going to borough a GP tester from a friend. It's about 60 outside but we just went tru a cold front the last month in the 20's. Oh I forgot to say that its got A turbo. And the trans does not have any fluid in it. The truck ran great when I parked it. Oh and a friend said to crack the injectors any ideas thanks

Would a clogged fuel filter cause the cranking but no starting.

fill your filter with atf, and you're going to need to bleed the air out of the fuel lines, crack open the first three injectors on the driver side, and crank till fuel comes out, usually it will start before you have to chance to close them so keep it running and tighten them down
