I just bought a 1990 d250 cummins from a farmer that was just sitting at his house and checked to see if motor was seized and it's not but he said it had been then for a couple of years anyway my question is should I open up the motor before I try to start it and get it running new to diesel world any help would be appreciated
Welcome to DTR!
I would doubt that there s any reason to "open" the motor up.
I would all check fluids first, fire it up for a bit, then change the engine oil.
I have fired up many an old 1st gen that was left sitting for years.
Usually they just need a fresh battery.
Depending on how old the fuel is and what sort of climate it has been in, I would suggest adding some conditioner, such as "Power Service Clear-Diesel Fuel & Tank Cleaner", according to the instructions. Drain some fuel out of the filter into a clear container, let it sit and see if you see any water or contaminants. If you do, you might want to drain the fuel and replace with fresh, otherwise conditioner ought to be sufficient.

OK thanks it's still has a good oil level so probably just a battery the oil change would you recommend a fuel filter before or after initial start up
I would put a cup under the water drain, and tap a little out it it looks like bad fuel.
It is looks good, I would say it would be fine to fire it up and get it back to your house before you do a lot on work to it.

I live in a really dry climate here in new mexico and thanos for all the help
Dry climate, so you probably won't have water, and hence probably no algae, etc. Can't hurt to check first though. Oh, here's something. Check your air intake. I have a 2nd gen that was sitting for a while, and here's what I found:

it was probably a hydro static lock! don't start it until you determine what caused it (coolant,or fuel)
a hydro static lock will go away over a period of time,( leakage through rings).... but damage could have happened when it first occurred .like i said, better find out before starting it!
Engine Hydrolock - How Water Can Damage or Destroy Your Engine ...
Dec 19, 2014 - Hydrostatic lock is a failure of the internal combustion engine, where the unit can't run due to fluid entering the combustion chamber above the piston and preventing it from completing its cycle.
