Does that mean it CRANKS robustly, if not? fix no crank or post that.
1994 trooper. (not starting wide open throttle to clear flooding>?)
is the 4JG2 is a 3.1 L (3,059 cc), EFI engine. V6.
this is 1 of 9 engines , used,
i think this 3.1 has a distributor ,
so does the cap off, rotor spin cranking, if not , the cam chain snapped.
next, is spark (i do compression first, but im odd that way, on old iron)
i check spark. i check it to all 6 cylinders using the time honored system. we all know, right>? with a fresh test spark plug, gapped correctly. got spark.
are you spark plugs old , never did the 60k mile tune ups, (repeats)
if the spark parts are old ,no car runs right.
you know the ,ole' cap,rotor,wires , sparks filters deal.'
the we check fueling.
i look at the spark tips, are the dry,? i try the test fuel test.
if car runs for 3 seconds on test fuel the engine fuel system is dead.
check fuel pressure next.


watch scotty do his magic.

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.


3.2 L 6VD1 SOHC V6
3.2 L 6VD1 DOHC V6
3.5 L 6VE1 DOHC V6
3.0 L 4JX1 TD I4
3.1 L 4JG2 TD I4
