I've got Isuzu KB 250 D 2005 turbo , the engine has been overhauled,diesel pump serviced now it has got no power the speed can't really exceed 120 and is using a lot of oil

The only tune-up procedures for diesel engines are to change the fuel filter, drain the water separator and check engine speed. If the injection pump or timing belt have been removed, pump timing must also be adjusted (see Fuel System ). See General Information And Maintenance for filter and water separator service.

KB
Welcome to the USA Fixya.com forum!
we don't have KB here. sorry.
History.(1 line, all bad)
2005 - Isuzu dealers in the United States have only one model, the Ascender SUV,
and guess what?, it's a rebadged GM car here, no more cars here, real isuzu.
KB are in Africa, Australia and in EUROPE not here in USA. so no books here to cover it.
nor is it covered here, at our great ,Mitchells online.

The KB300 is a 2.999 liter diesel, some are TDI. (most?)
and is called the 4JJ1-TC. (t= turbo)
That is direct injected, (means check turbo , and scan it first) after checking fuses.
The Check engine light on, same deal.
Check filters. for fuel and air.
2004 the D-max , family , introduced the DDI-ITeq common rail diesel engine.

So next time post your country.
And all symptoms.
power loss?
smoke?
Noises?
warning lamps.
etc.

our closest car matching yours.
is Chevy Colorado 2004_+
and Isuzu I-series.
both with GM drive lines. all petrol !

yet another post with no year.
no car stated, body model
just and engine, 4BDT diesel

no year, no joy, same with country.

my guess, is fuel pressure is wrong, or its regulator.?
get the engine service by a diesel mechanic?
its running to rich. and that can be turbo issues. too.
it must spool up fast. and pump air (forced induction)

what country
what year,
what engine, exactly
this is a USA forum and our engines and fuel system vastly differ from all other countries, so.... ??????

first buy a cheap gas car, diesels are expensive to buy and keep going.
even better get and older simple car and overhaul it.
then when it breaks (keep the FSM book in trunk) any mech on earth
can fix it not needed and NASA engineer and $50000 in scan tools.
from the guy who knows now to....
$450 USD. spent is not much , here in usA, they charge way more.
and why own a suzuki, why not a far better Toyota. or Nissan.
suzuki is and underdog. infact backrupt here,Chapter 11, in USA and in Canada.
its like the modern day Yugo/Isuzu here..

my guess you are in India>? with Rupee's ?

Diesel !
cam ? timing? or the injector pump... ??????
ask Isuzu for a book.
wiki says, what is a space cab.>?? a 4,000 lb truck./van, sure.
