Isuzu Tropper 3.0 engine does not start

Hello people, I am new to these sides
I have a problem with a engine of Isuzu Trooper 3.0, which stopped being circulating x Consequence the problem detected was lack of oil x which would not be the injectors. To complete the level the truck started with a small injection failure (but it was) after 2 hours of having it underway the stop and the next morning I never started.
It is towed and it starts at 3000 rpm but if you get off these, it stops and does not start with a
good

Hi Pab: It would seem that in addition to being a safety block problem, the pressure in the combination circuit is defective. That blocks the incutors to say that the ECU HYACE for security, and until the rest of the system will be normalized to those rpm.- You would have to scan it and see from tedecta or what failures warns.
Luck !
