How to fix an injector pump of 4jx1 engine


this is a USA forum what country are you in?
Fuel systems vary by engine, and country, so......?????
what needs fix'n?

the word fix has many meanings
  • how to rebuild the pump?
  • time it?
  • how to remove it put back?
  • how to bleed it.
  • and on and on... or a lift pump or ?
try to say what you are doing "the job" and why,
or if not a job, must be diagnosing it, ?
say , im trying to test it or. what ever you doing.
we cant guess, what fix means.
Diagnosing direct injection?



The 4JX1 is a 3.0 L direct injection diesel engine, turbo, some intercooled, which replaced the 4JG2 in the Isuzu Bighorn/Trooper/Holden Jackaroo.
It uses unit injectors and 4 valves per cylinder.

European and Asian buyers could opt for the diesel.

see we dont have this.
troopers are sold in Asia too, but not here with diesel.

Necesito el diagrama del cicuito electrico de un motor isuzu 4jg2, del 2004, de una isuzu Bighorn, donde lo puedo conseguir


spanish on English forum? really?
I need circuit electrical diagram of a 4JG2 Isuzu engine, 2004, an Isuzu Bighorn , where I can get it.
what country? we cant guess that, and i guess you dont know engines ,EFI , spark and many parts are all different by that fact.
if the USA car on this USA forum is a 4JG2
then all this is found at alldata.com
it a diesel engine, and we dont have them here.
it is direct injected diesel. sold in most markets, but not here.
Our isuzu dealers are gone now, they left uSA. for passenger cars.
so cant go there.
then go to yours and ask them?
"In 2002, the Trooper was discontinued in the United States."
so now i know car is not a USA car. and that our books dont cover cars not sold here.
so why not ask Isuzu this, go to the dealer buy the FSM book.
or join any non USA forum for isuzu. trucks. troopers


try here, link is random

http://forum.planetisuzoo.com/viewtopic.php?t=16663

they speak english only there too.
i dont see any spanish speaking isuzu forums.

best wishes.

We live in New Zealand and own a 1998 Isuzu Bighorn, 3.0D. About 3 months ago it started idling roughly and stalling just after starting. Then it stalled on me when I was driving 70kph. It also has no


wow first post ever posting country ,what a brave person. !!!!
welcome to USA forums ,that have no such car.(truck)
the line up. (wiki list) so its 3.0L 4JX1
stalls and lost power.
The 4JX1 is a 3.0L direct injection diesel engine, turbo, some intercooled, which replaced the 4JG2 in the Isuzu Bighorn/Trooper/Holden Jackaroo. It uses unit injectors and 4 valves per cylinder.

can be caused by many reasons. get it scanned yet. ?
or see FSM book on flash codes from the direct injection fuel
controller? (per this engine option and market)

does turbo have proper boost? (PSI boost or +1 bar boost?)
does it even have a boost gauge.?
there are over 50 causes, of stalls (most inside engine)
but its not getting boost or the injection rates are wrong.
there are basic tests for each covered in the FSM
Factory (oem) service manual, with coverage for this engine.

Isuzu 3ltr turbo diesel no fuel to injectors


this is USA forum, and we dont have this car.
IT'S NOT A USA 2002 DIESEL trooper.
that and exact engine, size.
we have, 3 gas engines, 2.2L,3.2. and 3.5L
here. only and books that cover only those 3 engines.
so if a diesel dies.
what>?
check fuses.
scan it.
check filters
try test fuel to see if it runs on test fuel
test the glow plugs yet,?

if pump pressure is dead,?
check, power to the pump yet? (fuses are first)

there are 4,.6 and 8cyl. diesels by Isuzu.,
which is it>
they have names.
7 diffr. B engines, 3,xxxx liters.
and
5 diffr. 4Jxx series engines.
my guess is the engine is.
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4

wiki says.
"
European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1-liter (later superseded by the more problematic 4JX1 3.0-liter of 159 PS or 117 kW)
4jg2 is indirect injected
4jX1 is direct.
apples and orange diffr.! injection classes. '

learn what's under that hood, then fix it?

what country
what engine, real names, not 3L vague-ness. please.
