CRD engine dramas

Sounds like it is something electronic that is failing when it gets hot. I had a similar problem on a sports car some years ago. I used the wife's hair drier to heat up electronic components one at a time while the engine was idling in the garage, until it failed. Turned out to be the electronic ignition module in the distributer (petrol engine). I confirmed it by spraying the module with a can of "freeze" spray, and the problem went away. I replaced the module and had no more problems.

Key feels tight. Barrel itself feels tight.

Changed the fuel cut off solubilisation and wiring loom. Still the same. Turbo checks out ok. EGT's I'm told are normal.
Does it hot or cold

Id swap the blue EMC relay with the Aircon one and see what happens.
Only do one mod at a time so you'll know what it is

Faulty ECU. New ECU from Nissan also faulty. Second hand ECU out of a wreck has fixed all issues. Total cost $475

Thanks to you all for your input. Very much appreciated.

Good to hear that the problem is solved. Did Nissan use their ECU to test or where you forced to buy it? How much are the ECU's when brand new?
$475 is not too bad for a second hand one.

Give it 15 minutes or so and it will start again, then shut down once more. Could take a minute, could take an hour. Completely random.
We haven't yet swapped out the ECU as we didn't have one on hand at the time. Nissan doesn't think that the ECU is the problem but they aren't ruling it out. Tested the fuel and it came up clean, before and after the filter. Swapped out the filter, replaced the fuel lines. Swapped out injectors and glow plugs. Still the same. TPS working correctly. CAS has been swapped out. Cylinder compression across all 4 cylinders is within range. Nissan are scratching their heads.

Glad to hear everything is solved mate.
I'd hate to imagine what this exercise was worth. So I'm guessing now you have new injectors etc after all that.

Nissan put in an ECU and its still the same, goes to show you just cause its new doesnt mean it will work.
Glad its all fixed and not too many $$$$. happy trails

Before I knew Mudski, I bought a MAF from Nissan and it was faulty. Returned, swapped for another one and all was well.
Mind you the bloke behind the counter was a w@nker, as he didn't' believe me it was stuffed. Car ran like a bag of crap.

Reading through this and my first though was the ECU. The DSE, or now DEPI, used to run all Patrols a few years back, and now are Yotas . They had terrible issues with the utes and one of them was the engine would just simply cut out at any given time. They self diagnosed the issue themselves and found the ECU was to blame. At the time Nissan didn't want a bar of it, and the DSE had put lock out tags on their entire fleet of over 200 cars. I remember working at the DSE in Benalla a few year back and there was maybe 60 or so Patrols all parked up with lockout tags on the steering wheels.

Great to see its all sorted.

:frown: That doesn't sound too reassuring. 200 cars?
I assume they all didn't have the problem but the dept. wasn't taking any chances with OH&S. Sounds like it could even be a current problem if the new ECU had the same issue. I wonder what the failure rate is?
