I have a 02 / 00 isuzu npr 300 truck Vin JAANPR71LX7102025 I would like to know the engine number an where it is located

no country told ,no VIN told, no year truck told
the fuse blew.
but gee no year told. nor what radio is there OEM day 1 Isuzu or aftermarket radios of 1000000 kinds

try dealer

What country is the truck from & what is the VIN number & what system do you need. They are split up into different systems. e.g. engine control, tail lights, headlights etc...
if in Australia ring North East Isuzu at Burton & ask for Steve technical help.

what country NPR
what year.
what transmission is there, we cant guess boxes, used world wide.
nor matching engines, lots.

youd need the NPR heavy truck, FSM book page on radio wiring
buy book at any Isuzu heavy truck dealer.
we dont now what radio option cam on that NPR
nor what country , other countries use different radios.
so..... this is USA forum, and we dont have NPR books.

this is no heavy truck forum. its only light and cars.
NPR what, (the number)
and what engine? fuel parts match up to and engine.
no year NPR. wow. and have gas or diesel engines.
no fuel stated either.
NPR started in USA in 1985 (this is USA forum)
this?

what fails?
what country?
what exact engine? boxes vary by engines, fuel systems , spark and EFI used in that country.
what exact body, NPR something.npr 200, 300 ,400,500
http://en.wikipedia.org/wiki/Isuzu_Commercial_Truck_of_America,_Inc.#1991
or if not in USA this....
http://en.wikipedia.org/wiki/Isuzu_Elf#Sixth_generation

is it gas or diesel>? CNG? 300.

what year.? surely it has a VIN, and that has YEAR.
the books are ALL made for one year. (accurate.....!)
and if you cant know that, how can anyone look it up for you.?
this is a USA forum and our books don't match yours. (if not usa)
and if we look it up in alldata.com, it will be USA answers.
see>?
and you cant find a fuse box in under 5min works , under dash and hood.? i find that hard to believe..... ? but answers above will help 100x better.
LIKE:
dash under, kick panels, behind glove box. ? (covers that hide them)
then under hood how can a fuse box hide ,its in plain site if there.

With your eyes

The vin # does not get higher as the year goes up, the vin # each number has a meaning to it, for example body code is one number then year then engine type and so on, it does not start at 1 and go up as the years do, hope this explains it good day

It should be on the side of the block 4ZE1 would indicate a 2.6L and yes a 1988 came with this engine with fuel injection.
