Hi,

I realise that this is a nissan note forum but I believe that some nissan notes have the same engine as the nv200 I am working on and I am struggling with it, I hope its ok for me to post this sorry if it isn't. So I was wondering if anyone here has any advice as the only nv200 forum I can find does not have a technical or repair section.

2011 nissan nv200 1.5dci k9kc400 engine.

A bit of background info..
My dad came back in his van and it was making an internal tapping / knocking sound. The engine started fine and seemed to run fine other than a bad tapping noise. sounded a bit like worn hydraulic lifters do. I initially removed the cam cover and sump to investigate, Found they were bucket lifters and the valve clearances and big end shells were all fine.
Then I decided rather than investigate further it would likely work out quicker to change the engine for a second hand one so I lifted the engine and gearbox out. It was at this point that I discovered that it had a k9kc400 engine and the cheapest one around was over £950.
So, I removed the timing cover and found the timing belt was damaged on one edge and the belt had slipped a couple of teeth. I replaced the Belt and water pump and set the timing correctly using proper pins, then I compression tested the engine and got in the realms of 300psi on all 4 cylinders. So I assumed no valve damage and refitted the engine.

When everything was back as it should be I turned the ignition on and checked for fault codes before I attempted to start it, No Fault codes...
The engine cranks but does not start or fire. Still no fault codes.
The engine will start on easy start but will not continue to run on its own fuel.
Live data reads 300 bar fuel pressure it does fluctuate a bit though (which I assume is the pressure relief valve )
RPM when cranking reads 200 - 220 rpm
I have also tried replacing the crank sensor.
Crank/Cam sync changed from "not done" to "Done" on live data when you crank the engine.

I have replaced number 1 injector with a Brand new one because I damaged it when testing. so number 1 injector is not currently coded to the ecu, but I have read that the engine should still run and that coding it only fine tunes it. ( Then theres the fact that the engine still didnt start prior to me damaging the injector )

I have removed number 1 injector and turned the injector pipe round and reconnected the injector and it does spray diesel out when cranking, so the ecu seems to be sending the signal to the injectors for them to open.

So to summarize, Its got compression, fuel pressure, starts on easy start, Injectors are opening, It has no fault codes. It started fine prior to me removing the engine.

Does anyone have any suggestions as to what I could be missing??

Thanks in advance,

James.

Hi James

I’ve just done a head gasket on an nv200 and after completing it I’m having the exact same problem your have, I have fuel and pressure, timing right as I’ve just checked it again and I’m getting the same not synced to synced when cranking. Vehicle ran fine “except pressuring the coolant system” before I pulled the engine out. Hoping you got somewhere with this and you could help me out👍🏻

Thanks in advance

I don't know much about these new fangled diesels I'm afraid, but

1) the DCI can be a swine to start if air gets in the fuel lines, massive amounts of priming required, and possibly crack the line to the injector to bleed air out (they self bleed when they are running- except they don't ever get to run)

2) as it has been apart, double check the fuel pump timing. Apparently, it is easy to get it 180 degrees out- I can't see how if the marks match up, but that is the advice I found. (tbh, I don't really understand why you need to time the pump on a common rail engine in the first place, but I think it is because the cam position sensor is on the pump not the cam- nice one Renault :) )

Here is what I found Micra 1.5 DCi (K9K) won't start - fuel

Hi Astin,

Sorry for the slow reply I have only just seen your reply. I did manage to get it started. I did this by disconnecting the plug on the pressure relief valve on the fuel pump and it started straight away. I reconnected the plug as soon as it started. then I switched the engine off, cleared the fault codes and it started every time after that.

I think The cause of the problem is disconnecting the electrical plugs on fuel pump. The correct way to solve this problem is probably by re-programming the fuel with nissan consult or other diagnostic tool. But the way I described above seems to work as I have done it twice now.

Hope im not to late sending this message and it helps you out.

Cheers,

James.

Yeah on some 1.5 dci engine the cam sensor runs off the fuel pump, on the k9k400 I worked on the cam sensor was on the cam and the fuel pump was not timed, BUT... The correct way of tensioning the timing belt still involves a mark on the fuel pump pulley so it still really needs to be on the correct position. Its all a bit over complicated if you ask me lol.
The cause of the knocking I had originally was a sheared woodruff key on the cam pulley which meant the timing was a couple of teeth out even when all the marks were lined up. I eventually got it started by disconnecting the pressure relief valve on the fuel pump and it started straight away.
