Hi! I have a new to me MEP002A generator that was purchased at a local army supply store. The previous owner changed his plans for using the generator and decided to sell. The story I was told was that the generator was working fine and then one day it wouldn't fire and he didn't want to mess with it. That's the condition I got it in. Things I have done so far:
1. Drained old fuel, replaced with new and run new fuel through all filters
2. Confirmed there is good fuel flow getting to the IP and returning to the tank
3. Confirmed fuel shutoff solenoid is working and lifting up while cranking
4. Confirmed glow plugs are working (I live in Hawaii though so no warm up is needed)
5. Confirmed IP plunger moves freely via O.D.Fever's method of removing the large hex nut and using a punch. I didn't even need to hammer it moved very freely. The hex nut was also only finger tight so I guess another possibility since I don't know the real history of the unit is that someone messed with the IP or rebuilt it but the timing is off. I've never checked anything like that so not overly anxious to mess around with it but if it's the issue I guess I will have to. I just want to rule everything else out first.
I have still been unable to get the generator to fire. It cranks and cranks but doesn't want to start. There is no white smoke while I am cranking. I have read a number of threads regarding starting issues and am quite sure it is not getting fuel but I don't know why. I took the high pressure fuel lines off and the IP is pushing out fuel all the way to the injectors but when I have the lines attached and just crack the nuts the fuel doesn't spray out, it just kind of dribbles. I included a couple of videos that will hopefully help. I'm not sure I'm getting the kind of pressure I should be.

My main question is can anyone shed some light on what to try next. Is my IP bad? My injectors? I'm sure I've left some information out so please ask away!
Thanks a lot!
