zd30 common rail severe lose of power very hard to start

[pootrol07]

Hi guys, i have a 2007 stl patrol zd30 only done 113,000kms.
Problem i have i noticed it was getting hard to start, now just wines over and over and only just runs.
I noticed the green light on my dp chip had gone out so i disconnected it and still the same problem, almost like no rail pressure? Also now have an engine light.
When driving the car i cant get it over 30km's.
Has anybody experienced this problem before?

Hi welcome.we as you do an intro first before asking questions.
Sounds like limp mode. Disconnect batteries for an hr then try again without chip then try again with chip see how you go

As suggested pop over to the intro first just a courtesy thing before asking for help.
It's what the forum asks from all of us, you'll get more replies too

Thanks guys I introduced myself, I was just in a hurry and stuck yesterday.
Anyway I have put a scan gauge on and come up with a fault code po190,fuel pressure send/circuit
I have no power to my dp chip, no green light
Also undone the main fuel line going into the rail and had no pressure or fuel coming out
Left the line off while cranking and only got a dribble..
The only way I can get it started is to manually prime the pump with the squeeze thing.
Thinking maybe a buggered injected pump??
Anybody have anything similar???

possible blocked fuel filter ?
I am not sure but I think there might be a fine gauze filter where the fuel line goes into the injector pump , this may need cleaning .

Pootrol,

I would be looking at the fuel filter, as it is due for replacement at the 120,000 k service, and it may be blocked

I dont think there is another filter in front of the pump on the Common Rail ... the gauze filter is on some of the 4.2 D Pumps
