1.6 NA issue

i purchased a used 1.6 NA off a guy, when i crank it over by hand to make sure everything rolls nice i get a bind at the same place almost a full rotation of the crank when i roll it back the opposite direction it stops on almost the same spot. i haven't had the timing belt off nor did her motor ran when pulled but it has been quite a bit of time. since it has ran. and a critter made his home in the air box. havent taken the intake completely off yet nor the head or anything i realized those would be ideal but i wasnt sure of any things to check like taking out the injectors and seeing if theres pressure or fliud built up etc
My theories
Timing somehow loosened up over time?
?
Something is in the Cylinder not allowing to to roll over? Fluid rust or critter junk?
Please any suggestions would be awesome owner said that he would refund me if it was no good.

So I've pulled the head reace head gasket and used arp studs put the motor in time as well as the pump timed too. Now that its all back together I can't get it to start. Tried bleeding the system of air by cracking all 4 lines to the injectors even tried to tow start it no dice any suggestions I'm a big newbie to diesels

I'd probably:
- check the compression. Rings or valves might be shot.
- crank it with the injector lines off, to see if the IP spits fuel from each delivery valve.
- "pop" test the injectors, or put them on the IP assbackwards to see if they all spray.
Diesel needs air, fuel, compression (>300psi), timing... the rest is tweeking.

Most likely: air in lines or timing.
Low compression will make hard starting, but not usually white smoke.

My bet is on a leaky mainshaft seal on the injection pump. Been there, done that

run off jerry can to see if main shaft seal/internal pump weak/failing.. sucking fuel from can on bumper less effort then from tank.. also eliminates all the filers and other lines to it.. for test.. if its just fine off can.. then you can look at other things... main shaft seal leaking should drip fuel.. but weak suck pump.. ok add electric booster pump if so..

When my mainshaft seal was leaking there was no visible dribble. The only indication was I only noticed a wet edge on the back of the timing belt

i changed the pump to a know working pump.... no leaks i can see.. recently here are the things that i have done changed the in and out line to the pump to clear line. changed the starter because it was weak as hell and now im pop testing my injectors....
Small issue i found was #4 cylinded Injector had air creeping up through where it seats/threads into the prechamber, when i pull the injector it was dry and had some carbon build up... so thought bad injector... so now ive installed new heat shields where all the injectors are... and after having them pop tested im going to see whats up and report back.
And btw thanks for all the help ive been learning alot on my own so far reading... one day it shall run!

Well I'm going to guess my issue is pump timing pop tested all the injectors they are all good cleared the fuel lines of air... When it idles it will idle fine the act like its going to die then idle fine the lug down u get the idea.... Pump timing?

Either it still has air in it or your filter is plugged/junk. I would think it to be fuel supply related
