Jackaroo 3.0 turbo diesel won't start!

Flat battery / dirty battery terminals. Maybe the camp fridge has pulled the battery too low.

Is he a member of an Auto Club - NRMA, RACQ,etc?

Use Google. Look for a forum. You could just search using your thread title here - Jackaroo 3.0 turbo diesel wont start.

Once you have found an "expert" you want to ask the location of any fuseable links. These sometimes look just like fuses but can also look like a wire. You want to ask for ECU codes. The check engine light flashing will most likely be a number code like morse code, ie long and short flashes. The code number that it is flashing at you is the problem. You need the code list to look up the number.

While you are waiting for an answer there are a couple of things you can try. First re-set the ECU. The ECU is simply the computer. To re-set the ECU simply disconnect the Neg battery terminal wait 10 to 15 seconds and put it back on. Try starting the engine. If the engine starts remember you still have a problem that you need to find. If the engine still does not start re-set the imobiliser if the car has one. To do this you will need the re-set instructions which you can find on the net or someone here might know. For example my cars immob is re-set by turning the key on and off 3 time in 5 seconds.

Locate both the fuel pump relay and engine relay and check them. A faulty engine relay will not allow the engine to turn over. A faulty fuel pump relay will not give enough pressure for the injectors to work. If either is faulty you can bridge the relay terminal with a wire but if you do this remember to remove the wire when not driving as it might flatten the battery.

As the ECU is flashing (check engine light) at you there is charge in the battery. However, a loose or corroded battery terminal is often the cause of your symptoms. Since you will have the battery disconnected to re-set the ECU may as well give the terminals a good clean.

Hope that is of help.

hi gwray
dont have a jackaroo but some vehicles have a fuse in the starting circuit check under the bonnet fuse box as well as under the dash remove and clean both battery terminal and inside clamps not just the negative one
check the cables that attach to the starter motor make sure they a tight
check for and earth strap going to the engine and/or chassis make sure it is clean and tight
cheers

As others have stated the battery and connections are the first stop. In later models they came with 2 batteries to make the vehicle more reliable starting. After that the ECU should be checked out

If the motor is turning over and will not start particularly on cold morning you should be using a 10W something engine oil

Similar thing happened to our Musso....battery was testing nearly perfect but that was not good enough...put a new battery in and all was well...old battery went in to the caravan and will see out its life just running led lights.

Hi Gwray,
Has it been through water lately and if so it could be your starter motor has got water inside it. Had one up here last year with same problem. Pull out starter motor and clean it, test on bench and put back in.
Yours Andy

G/Day Mate, ...hold key on ,tap starter with hammer, ..maybe solenoid problems.


cheers Axle.

Hi Gwray

Did you find the problem, can you tell us what it finally was.

Cheers

Hi all, the jack we talk about is mine dad put the post up for me to try and shed some light! So a bit more info Christmas day (was a hot one in Perth) car ran great no troubles starting ect did about 30ks stopped for fuel then wouldn't start! Everything works fine got full charge in both batteries even tried a jump start from another car and the jumper pack but nothing not even a click from the solenoids! When I turn the key to start the check engine light flashes and the anti theft light stays on!! So towed the car home disconnected the battery over night then in the morning it started no worries! Today drove to bunnings (about 5ks) and when I came out same thing no start!! Towed it home again disconnected the batteries again for a few hours and it started tonight so I took it for a drive around the block when I got back it was fine again but after 15 mins wouldn't start! We even put the OBDII on her but no codes came up on the ecu!!!! Ive got no idea any one ???

Firstly a big thankyou to all of you who posted suggestions. After reading some earlier posts we disconnected the battery and left it overnight (had tried disconnecting for short peiod but no luck) and YES it started and did so repeatedly. I sat down to write a thankyou to this forum and received a call from my son to say it had happened again!
Since then we have been flat out trying everything to reslove the problem, including trying to explain to two devastaed young girls that there trip trip to Warrooro station is not happening.
It was most dissapointing therefore to get on this forum this morning to read disparaging comments about my lack of feedback.
Hardly surprising that this forum is dominated by few hard core contributors, and very occassional users like myself are reluctant to post in fear of being riduculed.
The Jackaroo problem is not resolved, we are seeking professional help.
