You can do that by cranking engine watching o/p gauge with either cable kill engaged or by pulling the wire from the solenoid on the injector pump.
3. Try starting...
After checking fuel filter for crap more than likely there is air in the system and you will need to bleed the air out by loosening (do not remove line from injector) the injector line on the injector if you have more than four cylinders crack two lines loose. Don't get discouraged if it takes a bit to bleed the air out it's not uncommon, although on a newer engine shouldn't be a problem.

turn over by hand, my thoughts
I would put a large socket and breaker bar on the crank bolt and try to turn the engine over by hand. This will let you know if the engine is seized or not, water logged or not, etc.
If that works OK I would make sure there is fuel, oil, and coolant. Then I would connect a fresh battery and try to start it.
If it starts and runs, I would turn it off after a few minutes. THEN I would change fluids, filters, impellers, belts, etc.
If it doesn't start I wouldn't spend another penny until I knew why. No point in spending good money if the engine is shot.
If you start off by changing things, and it doesn't run, you have no way of knowing if you did something wrong, or if there is something wrong with the engine.
Case in point. My new to me boat came with an engine that ran great - when I could get it started. Since I knew the engine ran, my diagnosis was much easier. In my case the glow plugs were not getting power because of a bad connection. When I cleaned the contacts the engine became much easier to start.
Then I changed the fuel filters. And the engine would not start. It was because I bled the primary filter and secondary filter, but not the injectors. Since the engine ran before I touched the fuel filters, it had to be something I did.
If I just started changing things, trying to get the engine started would have been much more difficult.

|EscapadeCaliber40LRC||Agreed, buy all the Nigel Calder books. You can't afford not to.|

From experience....make sure that the controls that stop the motor are functioning. Trace the control wire/cables from the stop mechanism back to the motor and make sure you know how to operate them by hand. There is nothing worse than gettig a laid up motor running again only to realize you can't stop it!
Check and change all of the fluids and definitely change the impeller. If it is frozen and breaks apart on start up, pieces of it can get lodged in your raw water pipes. Also it is good practice to know where and how to access the impeller and how to remove/replace it.
Assuming your boat is on the hard at the moment, make sure you supply water to the intake while she runs and minimize the time you run the motor in gear as you can burn up your cutlass bearing.
Good luck and enjoy the project!!
p.s. - Nigel Calder's book is great. Don't get overwhelmed when you first look at it. The more you poke around your motor the more sense it makes!!

|Freesail99||I just bought the one for $13.14, thanks for the tip|

All good advice above.
My recommendation is a bit different, though.
Take your last penny to the bookstore and buy Nigel Calder's Marine Diesel Engines.
At Amazon, it's $18.45 new in hardcover or $13.14 used.
Amazon.com: Marine Diesel Engines: Books: Nigel Calder
It's the best investment you can make to keep your Isuzu diesel humming.
