Yes. Not as long as cold start, but yes, it takes about 3 seconds crank to start.
How does the engine know what the pressure in different cylinders is? What is this witchcraft?
Sorry what is this SME?
I will thank you.

@poddy All good mate, SME is a Subject Matter Expert (eg: workshop that do Diesel fuel injector service / rebuild / repair and that have the tools and test equipment to check the injector serviceability.
Ring around local area, not sure where you are as someone around the forum may recommend w/shop.
Look not sure on injector sensors, but imagine a sensor would send signal back to ECU at time when same pressures are achieved in all injectors and initiate start. Others with more smarts may add.
For Info: My 08 CRD injectors were checked out 12 months back (originals_160,000ks), when fuel pump was replaced and all were within spec and she starts straight away always.
Have read that acceptance criteria is:
All 4 injectors _The maximum permissible return volume is 3 times as large as the lowest measured
Return volume.
This seems a lot but this is in accordance with Bosh documentation.

It sounds like a candidate for an injector leak test, one of the injectors might be leaking excess fuel pressure via the fuel return line.
An injector is about $400 on it's own. A mechanic will usually advise/recommend that you have the whole set replaced.

has the fuel pressure relief valve on the rail been tested?
i linked a test method for you
note: you cant buy the valve from nissan they want to sell a complete rail you'd have to buy a bocsh on part number 1110010018
it could be an injector but check the fuel pressure relief valve first and then go to the injectors.
there is also a valve on the injector pump that is common to fail on common rail vehicles but seams to be very rare on zd30 crd patrols but to test that you'd need a computer to monitor the sensors to determine if its out of specifications
Unless U already have a scan tool (to read trouble/fault codes), could be a good idea to buy one.
Many available, UltraGauge EMPlus is the one I use and is not too bad (OBD11 compatible). Apps out there as well.

to me they are both easy and simple tests, but from experience i feel its going to be the fprv. i may be wrong. leak back test is a good thing to be done anyway, cant loose by doing it.
thanks everyone, I've got the glow plugs on the way, will start with that; Like I mentioned earlier, I already found 1 is cactus (10.52Mohm); I've got a set coming in today, so I will swap them out - move on from there.
Just out of curiosity, when I was pulling the plugs out on the weekend, to check them, they were screwed in pretty loose. I mean, it took no effort to undo them from the block.
The manual says they should be tightened to 20nm, but when I last pulled them,they came out really easy.
I don't know what to make of it. Any thoughts?
