Isuzu C223 timing

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.

Fuel pressure regulator is located on the back of the fuel rail, back right of engine.

to what? transmission or is the EGR mod or?
what year, trooper.
and what engine.

modulator means zero.
the injectors are modulators, the ISC is, and many other parts.
the car has systems. name just one,
2.0 L G200 I4 (UBS13)
2.3 L 4ZD1 I4 (UBS16)
2.6 L 4ZE1 I4(UBS17)
2.2 L C223 diesel/turbodiesel I4(UBS52)
2.8 L 4JB1 diesel I4
2.8 L 4JB1-T turbodiesel I4
2.0 L G200 I4 (UBS13)
2.8 L LH7 V6
2.8 L LL2 V6
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 and many transmission, the body is a shell, the drive line is all optional.

this car must be a Diesel as this sounds of a injector pump failure , there are two fine machined plates with groves cut in them "inside pump" after a lot of miles these two machined plates are not so machined anymore and fuel slips by causing the symptoms your describing , pump will need to be rebuilt and flow bench set or replaced with allready rebuilt/set unit to get things back to normal

Sorry we do not have that info here.

This site has it .

Hope this helps!

alot of times they are pressed on requires a special removal tool

It sound like you have a timing belt tensioner that is bad. Is the noise at the front of engine? If it is replace tensioner,timing belt and water pump. The pump is driven by the timing belt.

cant start deisel 3.0 lilter sounds like there is no fuel getting to the engine
