How was it stored? I wouldn't even try firing a motor that sat that long before going through it thoroughly. If a valve was held open all this time, you could have severely rusted cylinders. If you crank it like that you'll score a cylinder and mess up rings. I went to look at a mid 70's chevy convertible that had been in dry storage, and not run, since the early 90s. The owner decided to get it running before I came. I saw the smoke from blocks away. ..he told me he put a new battery in it and fresh gas and it started after a few minutes of "hard" cranking. The thing was bone dry sitting 20+ years. A few shots of oil probably would have saved the motor.
If it was me, pull injectors and spray penetrating oil in the cylinders, soak the injectors with it. Let them sit 24 hrs. While they are soaking pull valve covers check for rust, penetrating oil if its rusty . Clean fuel filter pre screen, new fuel filter. Pull the thermostat. Pull the turbo of if it's seized. New oil and filter. After 24hrs, try turning enine by hand, keep spraying penetrating oil in cylinders until I can turn it by hand. Once I can turn by hand, clean injectors and reinstall. Make sure FSS of off, crank over to get oil pressure up and prelube motor. Then try starting it.
