Hi , the switch in the car puts the flap in the exhaust over for quick warm up and the flap in the inlet manifold is part of the ERG setup.The ERG flap works with the ECU and also when you hit the warm up switch .

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

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European and Asian buyers could opt for the diesel engine option of the 4JG2 3.1-liter (later superseded by the more problematic 4JX1 3.0-liter of 159 PS or 117 kW)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.

1993 isuzu bighorn diesel engine holds revs to 3000 rpm for about 30 seconds and then dies


Do you think the primary fuel filter under the tank could be blocked or water is in the fuel?

I cannot start my isuzu bighorn w/4jx1 engine. we already changed the turbo but still it emits too much smoke in the exhaust and after a while the engine goes wild and we cannot turn it off in the ign


Its a diesel and its running away so do not try to start till you do the following and yes i know i will be amolished for being a cowboy by the other experts but what you do is to make a gasket for the EGR valve from a coca cola can and seal it off if you dont it may run away and blow itself to pieces .If you do this then it run as normal as the older trucks never had these thing fitted and they all run ok in my day ,exactly whats wron i couldnt tell you without my head under the bonnet but do as i say and it run perfectly

My 1997 Isuzu bighorn (trooper) appears to "miss"


When is the last time a tune up was performed on the vehicle? I would get some amsoil engine foam, and use it as described. Also get some fuel system cleaner and use that as well and go from there.
Thank you,
Lee

John-meyer is right in having those injectors calibrated. If this wont cure your problem, have your valves, valve seals checked
