Question about Ford F-350
Most likely it is air bound. Crack a injector loose untill fuel comes out then move to the next one.

Diesel engines fire on compression alone (usually 400psi).The Truck may have air trapped in the fuel system.When you perform any fuel system repair on a diesel it is going to take alot of cranking to get the air out. You can take the breather loose and shoot a VERY small amount of starter fluid in the intake and it should start. Do not use starting fluid much as it can damage the engine. Good Luck.

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.

ford diesels from that year had a funky problem getting the crank triggers to work 100% of the time the software fix they refer to might be the one that alloud a poorer quality signal from the crank trigger to work , this is not a fix but a work around (no good)
first verify that a fault for the crank trigger sensor is held in memory with a scan tool (there not that expensive now)
if so replace it and don't forget to seal it with locktite blue (or it'll unscrew itself)
the trans od needs to see the crank trigger signal to determine "load" to high no Od bad signal makes eec go into can't decide mode and drops in/out of od
ohh a dead giveaway it's the sensor your tach will bounce (allot) at a fixed engine speed (2000 rpm)
also i just looked there's a TSB on throttle posisition sensors(oil vapor intrusion) as well affecting Od on transmissions but that being bad will make engine speed surge too and you did'nt mention that ?
yea EEC test is the way to go but get your own

check to see that your mechanical fuel pump is working on the lower right side of the engine. VERY problematic pump due to design and location. Have you replaced your fuel filter with the injector pump swap? cause you need to do that , its a must
If your getting fuel to your injector pump you have to bleed the lines to each cylinder to bleed out the air in the system.
If that all checks out then you need to set the timing to 8 deg using a timing light and a diesel injection pulse width adapter timing tool.
purchase a haynes manuel for 6.9l/7.3l diesel engines to follow the correct procedure for setting timing to manufactures spec.
You will have to disconnect sensor at certain times during the timing stage so make sure it is done right!
PS - I hope you marked a reference line on the pump to line up with the line on the housing cause that will get you close to start! good luck
