SOURCE: 4jx1 camshaft marks on isuzu trooper 2001 3,0 dohc

the timming gear that the belt runs on has a mark (V cut in gear) to rear cover at about 12 o clock and crank pulley has timming mark for top dead centre, both cams have cut outs in rear that a special tool (camshaft stopper 5-8840-2592-0) locks into to hold cams in correct position, but can do without this, if the cam belt gear is off, the keyway should be at 12 o clock. the marks in the camshaft gears (dots) is for assembly of sissor gears to solid gears on camshafts that run together and they should match up only if you had this appart.

stevenhurc_12.jpg no.1 is timming mark

The ECU will be fine with a engine rebuild but the 4JX takes a bit longer to start if all the injector oil paths are empty - can be up to 5 or 6 mins of 20 second cranking bursts.
Also if you rebuilt due to diesel in the oil from bad injectors the control valve for the injector oil pressure may be faulty so it wont start.

Sends a signal related to the rail pressure as a voltage to the ECM. 3 wire connector :

  • Red : 5V (Feeds from ECM connector J1-4) Shared with MAP sensor, EGR pressure sensor and accellerator position sensor.(compare values from these sensors and ECM connector)
  • Black : Ground (Feeds from ECM J2-22) Shared with the same sensors mentioned above
  • White : Signal feeds to ECM connector J2-22
Low pressure will set P1194 error code. Oil rail pressure should be more than 3MPa when cranking

Also check Engine coolant temp sensor and wiring. Engine coolant to manifold temp should not differ by more than 5 deg C either way after 8 hours of no operation. I have found the same symptom on these diesels with fuel supply problems. Operate the priming pump (on top of the fuel filter) until it becomes diffycult to push down before starting or checking anything else.

Testimonial: "Thanks Suzman, We actually managed to get it going....The only problem remaining is a rough idle until its warmed up and sometimes stalls until warm. "

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.
