Sometimes an air bubble - just before the injectors cause this problem. Loosen the fuel line there and crank the motor. Fuel pressure should force the air out and then fuel will squirk out. Turn key off and tighten up the line. Hope this is it. Other diesel fuel start tips are listed below that will help. http://www.auto-tune-up-and-repair-options.com/diesel-additives.html
When there is acceleration problems with diesels it is because there is low torque occurring in that particular rpm range. ( incorrect fuel metering) If you have verified that the turbo is operational then it will be a governor problem in the fuel pump or worn out pump. If it is a common rail diesel the run the fault codes or have an accredited diesel specialist shop check the program in the CPU ( may be corrupted). Blocked or faulty filters will give an indication under heavy load when there is maximum fuel flow required. If it is a rotary pump or in line pump I would be taking it to an accredited diesel specialist and have it properly assessed.
Try switching the fuel pump. Or before that, your fuel pressure regulator. The reason for no start could be because your flooding your engine. And the reason why is listed above. Hope this helps, James Booth

SECTION 303-04C: Fuel Charging and Controls — 7.3L Diesel
2000 F-Super Duty/Excursion/Motorhome Chassis Workshop Manual
DESCRIPTION AND OPERATION
Fuel Charging And Controls
Fuel System
The fuel system used on the 7.3L direct injection (DI) turbo diesel engine is controlled by the powertrain control module (PCM) (12A650).
The fuel system components consist of:
i dont know about the turbo going bad,but i do know that ive seen 7.3 diesel have bad injectors,usually 2 at a time, check for fuel at the injector which can get messy so wear protective gear such as goggles and gloves,while running crack open the fuel line at the injector to see if there is fuel,it should run rough which is good on the working cylinders,if it doesnt change then maybe a bad injector,or not enough fuel pressure at that injector.injection pump issues are another thing,but most likely its an injector.
Check all turbo hoses first for splits etc. It's best to remove each one for a thorough inspection. If they are all ok you need to locate the small rubber hose that goes to the top of the injection pump. Check it. It's probably split somewhere. this ups the fueling when on boost. If its not intact you will have very little power.
This system should be self priming, however if it did run out of fuel, I highly recommendchanging the filters.After doing so have an assistant turn key to run as you listen for fuel lift pump running,(under drivers side floor attached to frame, one of the fuel filters is part of pump,the other filter is on top of engine) Could have hurt pump by running dry. They are notorious for hard start after filter change and/or out of fuel.Hope this helps.
