Black smoke and loss of power

[p8ence]

3.0l crd 2009

So yesterday i lost power and then thick black smoke, cant go much over 3k rpm. Not using oil or fuel but getting up to 3k starts smoking and loses power like its coughing or starving for fuel..

Thinking injectors but im no mech...

Thanks for your help..

Hi mate, I cant help much because I have the old Di 3L, but there has been a lot on here about a relief valve thingo on the CRD injection rail. Anyone??

[jack180]

need to get it checked - fuel issues are the no 1 killer of the CRD. Ive read that those symptom are common with a failure of the Cam Position Sensor. Id be getting it checked out and the code ready by Nissan or a good mechanic with CRD experience and a tool to read codes.

Here is the way to check the relief valve. As Jack said, is there any way to get any codes reading ?
If you don't have a access to a scangauge , try going to Supercheapauto, I believe they plug in their tool and read codes for you for a small fee.
Thick black smoke may indicate a lot of unburnt fuel if I'm not wrong ?

You havent popped a boost hose off have you, remove the engine cover and have a look

Good point TD.
Still doesn't explain the fact you have diesel around the injectors on top of the rocker cover... (as per your other thread)

Black smoke and lack of power and ZD30 means only one thing = no air, check that VNT/VG turbo actuator raises up during engine idling and that vac hose to it is intact. Very common....

Ok got my power back, replaced my MAF sensor and she is running smooth, but smooth with clouds of black smoke.. i feel i'm fearing the worst here..
