Question about Ford F-450
If you have the 6.0 ltr diesel, then check the bowl where the 2nd fuel filter is, see if there is fuel in the bowl, if not then either your fuel pump which is on the frame under the driver's side in the water seperator/ heater has gone bad, or your filters could be bad, or the fuse to the fuel pump or the pump shut off switch which is located on the side panel at your feet on the passengers side, there is a reset button, make sure it has not popped and press it down, hopefully this helps, I had the same prob.

Check your oil level. If it is ok then a computer diagnostic scan should be done to have all the engine sensors tested and checked.

The only way air can get in the fuel line is if you have a hole in it! Problem of course is were? I would run the fuel line from back to front and back again. Look for any wet spot that you can find. You may even have to drop the tank to ba able to look on top. I would suspect the problem is in the line before the high preasure pump, being as you are pulling air into the system. I have seen leaky lines allow air in, but not let fuel out.

Most likely you need a new Ignition switch. The small "tickler" wires on your solenoid are staying on. You can disconnect the small wire from the Solenoid and then put a test light on it. Turn the Ignition to Start and see if the wire stays hot when you release the key.
Another problem you could have is the Starter has such a bad intermittent short in it, that it keeps the points welded together after the key is released from the Start position. You can get a starter Draw test done at some parts stores like Autozone or Oreillys to name a few, they do it free and on the truck.
Let me know the result please,

Tips for a great answer:
The only thing that keeps a diesel engine from running.. OTHER THAN A MECHANACAL PROBLEM.. is lack of fuel. Since it starts when you spray starting spray the engine probably does not have a mechanical problem 1. does the fuel solenoid open when you energize it?, is the fuel filter clogged?, is the lift pump working? Is there fuel in the tank? IF YOU HAVE RUN OUT OF FUEL YOU WILL NEED TO BLEED THE AIR OUT OF THE FUEL SYSTEM.
