the 4jx1 engine does not have an injector pump.
it is a common rail diesel and therefore relies on a high pressure pump in the tank supplying 4 electronic injectors fitted to a common rail, similar to most modern petrol engines.
To realize the compatibility between low exhaust
emission and high engine output, an HEUI
(Hydraulically actuated Electronically controlled Unit
Injector) system, has been introduced. This system is
comprised of a hydraulic system, fuel system, and
electronic control system, using a high-pressure oil
pump in place of the conventional fuel injection pump.
The oil pressurized by means of this pump and by
signals from the ECM (Electronic Control Module)
actuates the fuel injector provided for each cylinder.
Inside of the fuel injector, fuel pressure is increased due
to the high-pressure oil. The ECM detects the driving
state of the vehicle, forms, signals sent by engine and
other part sensors, which determines the optimum fuel
injection amount and timing, thus controlling the fuel
injectors. Thus high engine output, good fuel economy,
and low exhaust emission are realized.

What are the engine torque specifications for an Isuzu 4jx1 engine?
The 4JX1 engine torque rating is 333Nm (246 lb/ft) @ 2200rpm.

How do you reset check engine lamp for Isuzu wizzard 1998 4JX1?
Disconnect the negative battery cable from the battery and wait a few minutes then reconnect the cable. But, if the problem that caused the light to come on hasn't been fixed the light will come back on.
What causes oil and diesel to mix and causing a lot of smoke on an Isuzu 4jx1 engine?
If you mean that diesel is somehow getting into the oil sump and the oil level is rising then this is quite common with this engine and is due to either the injectors or the injector seals failing. Loads is on Google about this problem. This car was recalled by Isuzu to have it fixed. If a car wasnt recalled then its a time bomb and if injectors need replacing it costs a fortune.
Why is the 4JX1 engine problematic?
Absoluty the engine 4xj1 is an the better diesel engines developed for Isuzu Motors in combination with General Motors division Caterpilar, These engine is built in with an very sophistificated electronical diesel inyection hidaulic mix, in the engine are used the electro-hidaulic inyectors developed for caterpillar and one ECM maked bye hitachi electronics under demand exclusively i have all information of this engine and bigg experiencie. If you need detal information please write an e-mail to me and i reply any question totaly free.

What is the ECM pin out of the 4jx1?
there are 69 pins in a 4jx1 ecm. i think its hard to write it all don here. i have a manual here that illustrate all the pin outs of the ecm. for the person who ask this question, please send me your email add at iayanent@yahoo.com and I'll share the manual with you.
What cause too much white smoke or emission in 4jx1 after top overhaul and replacement of O rings?
suspect improper head gasket R&R, sorry.
Where is the location of hydraulic pressure sensor of 4jx1 common rail fuel system?
The location is where the oil rail and the injectors and the camshafts are the sensor is conected direct to the rail . You have to remove the aluminum intercooler , the plastic cover , and the aluminum cover to see the sensor .
