Isuzu 4JX1 EngineWont Start after replacing new injector

Maybe the throttle body has a fault or not connected.
Check with an OBD reader for errors.

Will not affect starting at all,just make sure you put the same viscosity in as manufacturer specs

Where are you finding this? Diesel and water would normally only mix if water was getting into the fuel tank. Are you sure it is diesel? If you are finding it in the coolant reservoir it is more likely to be engine oil. This usually suggests a blown head gasket.

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

If you like I can send you one. I need the make, model and year of the vehicle as well as the VIN number.

Kindly did you managed to change 4jx1 with 4jg2? Did you changed the gearbox? What modification is needed for this change?
thanks.

you need to set the timing to top dead centre and the flywheel has a little knotch in it set that at 6 oclock will start then

hi Steve. May be sensor camshaft/crankshaft I have problems not srart engine 4JX1 Isuzu Bighorn I replaced sensor camshaft [email protected] max russia

Buy a can of throttle body cleaner take off the air filter box, follow the tube and then spray the throttle body and wipe it out first before condemning the injectors

You have no injection pump ,each injector does that job .
You have a faulty rail oil pressure sensor I think ,read my tips to test this sensor .
