Isuzu trooper 2002 it started shut down started then it shut off .Now i try to start it and nothing no buzz no clicking nothing,the battery is fully charged. i just bought it. can some one please help


Try disconnecting a battery cable. Reconnect 5 min later. This resets the ECM. These vehicles are a real continuing problem when they get old. I had a 1990 Trooper II and finally junked it last year.

Trooper refuse to start unless primed by petrol and idles unevenly thereafter


Check glow plugs and valve clearances, both of these will cause bad cold starting, but once hot will start fine

Isuzu Big Horn (Trooper) 4JX1 engine.... Vehicle would start and only idle. Some time later it failed to start.. Where do we look for the fault Checked cam sensor and crank. Still need to check ORPS. How...


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.

1995 trooper wants to start in 3rd gear. A number of dash lights blink. I shift into 1st gear and it usually turns off but sometimes takes a moment. I checked the codes but only got results for a check...


The ECM not only controls the ignition, fuel injection and pollution systems but it also controls the transmission as well. It is very clear that when the auto was start with the jumper in the plug there was a short cuircut and the ECM was damaged severly and must be replaced

Where is the ECM located on a 1993 Isuzu Trooper?


If you don't have a coil pack working, unplugging the ECM will do nothing to reset the coil pack. If you have power present at the plug, you need a new coil pack.
