No, I mean 280bar NOT psi.
280Bar is standard starting pressure for most high pressure diesels. When under load at high rpm, the pressure can be as much as 2000Bar in the fuel rail, yes, 2000Bar!! Which is why you should never ‘crack’ the injectors on a high pressure diesel as they will invariably leak, unless you fit new injector seals.

Read the High pressure with a OBD2 and see if it is in spec, I can give you readings from mine if you need it, look at sirobb youtube , I think he shows it at 700rpm,

Many thanks guys I'll get on it

This explains symtoms and clear understanding of how Diesel injectors fail on a common rail system:
The fact your symptoms are a misfire, bad starting and long cranking are all indicative of a failing injector.

Not had a spare minute to get near it Dave. I have been assembling the kit to do a Liqui Poly purge on it. Trouble is I have to get my old dads house ready to sell as hes gone into a home now and needs the money! Up to my neck in work!
This will be the last chance for the D5 to shape up after the injector and EGR clean. If its still misfiring I have no more time to waste on a car thats SUPPOSED to be my run about to use whilst I get the 2 T5's repaired and MOT'd! Its let me down from day one if I cant get a decent price for it I'll scrap it - IM THAT angry with it.
I never thought a Diesel Volvo would be such a POS!!! I was looking forward to trying out a Diesel on the long runs I do - but after this experience i will NEVER buy another diesel anything! My PETROL T5's never miss a beat the V70 even got me home on 4 pots once when it lost a plug! THATS RELIABLE!
I'll update you when I can get time to work on it.

ok
I hope all is well,
let use know how the car is,
good luck, Dave
Today I actually got a few hours to work on the 'heap' so did the diesel purge. Sadly NOT ONE BIT of rubbish came out showing that the injectors are SPOTLESS! However as I had to remove the fuse for the LP pump in the tank, whilst running on the purge jollop........NO MISFIRE???? I ran 1 litre of DP through the injectors roughly 45 minutes with varying throttle opening particularly the misfire range of 1500- 2000. Im not sure though as there MIGHT still be a little roughness there.
A chap in a unit next to mine came in, he runs a small garage and he showed me the injector looms often fail on the D5!!! I removed each one and reseated it but they do need cleaning with electrolube. Replaced all the pipes, replaced the fuse started up for leak tests again NO MISFIRE Hmmmm??
The only way it manifest sitself is on a run on the motorway between 20 - 30 miles then drops into 'wimp mode' so I need to take it on a test run one evening when the flippin sun has ****ed off so if im stuck on the hard shoulder I wont be dying from sunstroke! Anyway if this thing fails on me again its the cutting torch for it or ebay! It was SUPPOSED to be a run about to get me around to sort my T5's out and its failed miserably! The chap with the garage told me "D5's are great when they behave - but if they get a problem - look out!"
Running the purge
Nothing yet in the jar?
After test NOTHING no debris or anything so a clean injector system?
Fliter also spotless??

Hi it may be worth tacking out the fuel pump and have a look at the filter on the fuel pump in the tank to see if it is a restriction also get a cheap £10 low fuel pressure gauge
and connect it up to were you now have new clips an see if the pressure is constant,

On VIDA the fuel rail is at high pressure according to readings?
Ill take it on a road test to see what happens! If it goes again ill take in limp mode to the nearest crusher!
Thanks dave

Hi The in-tank fuel pump is low pressure ,
Dave
oh DUUUH yes of course, what sort of pressure would you expect to see?
