Question about Holden Jackaroo

1 Answer

1999 Jackaroo V6 auto will not start all the time. There seems to be no common series of events that lead to the engine not starting. When the problem initially started i would purge the fuel fro the fuel rail and then it would start. I've had the fuel regulator replaced & the issue disappeared but returned again after about 20 starts. The revs do sometimes surge on idle, and I get only between 380km & 400km per tank of fuel

most likely idle air control sensor or low engine coolant I know sounds funny but IAC uses coolant to regulate idle. Idle air control valve or throttle body positioning sensor.

I have had the same problem, replaced everything. Have not solved it. Sometimes car stops completely whilst driving. Your problrm will only happen when air con is on. There is a small electronic box under glove box. Turn small dial to the low postition or high, whichever fixes it and also bring your revs up with the idle screw on throttle body. I still have not solved my engine cut out problem, must be a faulty relay. I have replaced the computer and distributor but still have the problem

The error P1130 and P1131 is for the fuel trim and lean fuel mixture respectively. This tells me that this may be an issue with the air fuel mixture or its reached its limits in compensating for the incorrect mixture. You could try to clean out the intake first using carb cleaner spray or tuner spray to clean out the intake and the MAF sensor which measures the air that comes in. Check also if there are leaks or gaps on the air duct found between the air filter and the intake manifold and the intake plenum. Leaks would cause the system to get an incorrect reading. If it were a faulty sensor you should get the error code for the sensor and you may have issues starting the engine up.

Check also the vacuum hoses which may be loose or cracked that needs replacing or refitting. This is also a common cause. I also do not rule out the possibility of the fuel sensors going or starting to go bad. The PCV may also need cleaning or replacing.

With all mentioned items go check first the leaks of the intake system and the vacuum lines as these are found to be common. Some leaks or cracks are minimal but is crucial to the sensors.

This is an indication that the fuel system is losing prime. It might be because the injectors are not sealing when the engine is off and the gasoline is syphoning back to the tank.

The jackaroo will idle only, if you touch accelerator pedal at all, it over fuels real bad and misses, least it starts but it won't run past an idle, it then misses and backfires real

  • 1999 Olympic Jackaroo V6 3.5L. This vehicle has now travelled some 366,000 kms. Ok so it is now 14 years old and few bits are wearing out. First the EGR and now MAF sensor and the MAP Sensor (?) - replaced both as a P0101 code is a little non specific. Now these parts are amazingly expensive locally - quote from Holden for the MAF was $350 and other sources anything from $150 up 2nd hand. The MAP was more reasonable at around $100+.
    Do yourself a favour and check out sourcing parts from the USA. The Jackaroo was sold in the USA under various brands including Isuzu Trooper. Also get yourself a copy of the workshop manual and Scangauge to help with diagnosing problems and improve your fuel economy by retraining your LEADfoot.
    A couple of sources in the USA that you may find helpful: [MAF sensor - MF8302]
    and [MAP sensor - AS60]
    Both companies will answer questions and confirm compatibility of parts by email - 24 hour turnaround in my experience.
    You can use the vehicle compatibility function on their web sites to check whether the part is compatible - Use "1999" "Isuzu" "Trooper"
    Now the good news and the bad news, the good news is that the parts cost in USD$54 for the MAF and USD$9.95 for the MAP postage was $44.10 and USD$19.99 respectively. The bad news is it will take a week or two for the parts to arrive. If desperate you can pay extra postage for expedited shipping.
    In any event you will be much better off in your hip pocket.
    Fitting the parts will take you about 10 minutes to swap over and that will save you at least $120 with current mechanic rates. You will need a large phillips head and straight edge screwdriver for the MAF and a 10mm socket for the MAP - most of us have those!
    So you can spend around $600 locally or you can spend less than $150 for the parts including postage (and $99 for the Scanguage on off) and fit them yourself.
    I hope the above is useful for another Jackaroo Owner - they really are an incredibly well built vehicle and if you look after 'Jacky' she will look after you.
