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 .

SOURCE: Fitting 3.1ltr diesel engine to Isuzu Trooper

Be careful............if the engine you want to fit is made by VM, these have individual cylinder heads. In Europe they have given  a heap of trouble and have to be replaced when they overheat.
If you have a friend who speaks Spanish, get him/her to surf  the net and have him/her translate some of the stuff I've read about here in Spain.
I am looking for a Grand Cherokee and have been advised to look for the 2.7 model engine which is a derivative of the older Mercedes engine.........they last forever and spares are easy to get.

SOURCE: 2000 ISUZU TROOPER WITH AUTO TRANSMISSION. CHECK

If the fluid is up -
it could be a vacume loss or the shifting module..
The shifting module is what tells it to shift - and it is controled by vacume pressure..

SOURCE: 2000 isuzu trooper: OBD-II Trouble Code: P0401 Insufficient EGR F

Your SUV is really giving you a hard time, lol. Sorry but I've had those days too.
I would try to check if you have blocked EGR passages. If ok check for restricted MAP sensor vacuum hose/passage or restricted exhaust. I know you replaced the CAT but if the muffler is blocked then there would still be a restriction. Also check the wiring and connection to the MAP sensor.

SOURCE: Isuzu Big Horn (Trooper) 4JX1 engine.... Vehicle

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. "

My 1998 Isuzu trooper when cold it has delayed shift fom first to second then it shifts ok


sounds like a dirty oil or filter problem. It is taking this long for the viscosity of the oil to change to allow shifting. Run fault codes as well consider having an oil change done on the transmission ( oil colour should be cherry red not tan coloured.)

1994 isuzu trooper 3.2 dohc automatic will not shift into 3rd gear it will shift into 2nd gear and at around 40 mph goes into like nuetral and sets a 61 code after that hapens it will not shift out of 1st...


The 3rd clutch pack is very cheezy on this unit (4L30E). The 3 speed version of your trans was used in the Chevy Chevett back in the late 70's early 80's (GM's THM 180). Check the oil condition for a burnt smell. Other items to check are speed sensory, and the shift soleniod (I don't know what the codes translate to). Any issues with reverse? If you'll drop the pan of the trans you may find debris. In this case it very well may be internal damage (clutch pack for example). Don't bother with changing the filter or adding additives to solve this problem.<br /> RTB - ProBuilt

Isuzu Trooper 1997. Automatic Transmission holds gears too long.


Their is a power and normal drive in trooper's power for pulling a trailer and normal for normal driving. The power drive only changes gear at higher R.P.M. Their is a switch on the plastic cover under the handbrake with p & n their is a light in the dash as well. If you are not aware of this switch then just needs switching over if you are aware of it then its probably the fuse to activate it or a wiring problem with it, Cheers

The dash transmission indicator changes without any gear change


trans nuetral saftey swich needs replacing
internal switch contacts are shorting together causing the PRND21 lights to move when this happens the trans ECU doesnt know what gear its in which causes clunky shifts and can lead to check engine light coming on

Transmission shifting into nuetral


Check your fluid level. If the fluid level gets low, the pump basically pumps the pan dry in which the trans. valve body has no fluid to direct to keep in engaged in gear. Check your fluid level while running at operating temp. in nuetral. If this checks out ok, the trans. clutches are worn out to the point of the trans. no longer has the ability to stay engaged.
