If it's turning slowly then yes. But a good battery will only allow it to go so fast. Easy start much faster building pressure very quickly.

jamesmartin said:
yes but my point is enough cranking will start an engine were diesel has leaked back,thus proving its that

Yup, useful as a diagnostic tool ...

if your diesel engine wont start...give it a squirt and if it runs for a few moments then you have a fuel problem...if it still wont fire on ether or lighter fuel then its likely a more serious mechanical problem ...or you've fecked it earlier ...

thats not real life though

I've repaired a fair few, maybe the newer engines are not as tired ...
Remember, the old Leylands & AEC's had built in start pilot assist ... or a burning rag waved over the air intake ... let alone a cap full of petrol tossed in ...

true but a good battery or jumper leads would start it

Tried a jumpstart booster on it and it just turned over without starting

If it pressurises at normal cranking speed it's not really faulty. If it has to spin at more than cranking speed to start its faulty. One injector leaking off too much can do this!
Also can be knackered or contaminated fuel

presumably over and over ,if speed is necessary and not time cranking i wouldnt be looking at air but hp pump, a worn pump wont achieve pressure till a high speed is attained whereas air will be purged over time

Could have blown a ring and not be compressing well ...

true that could give to low a pressure at cranking speed also

Is there a face palm button?

if your an arse there might be,i missed the previous post ,but still what ive said is correct

I see things around here haven't changed. You clearly haven't grasped what I'm saying. I'm not surprised it's so quiet on here these days. The same old names ramming their views down people's throats. I really hope the likes of you and wammers don't start breeding. Don't think I could take the arrogance of it all.

hi guys

would a hawkeye be any good for this, as I'm not to far away

just wondering if it may show up a dtc, as I also have a td4 auto , could compare the findings between the two hippos

Do you venture out into the rest of the world to discover how much this forum gets slated for the attitudes of its members. There's a lot of knowledge on here. But people hate it. You're killing from the inside out

Diesel Do · Dec 13, 2015

Spat over. I'm off see you in a few months when I can be arsed

neither have you it seems, since consensus is lack of pressure for whatever reason,and ops mechainic is thinking of fuel running back through loss of seal ,and i did acknowledge your post , i think you have an attitude or a chip to take it as you have

You talked over me every time. Not grasping what I'm talking about hence the face palm comment then you basically call me an arse. It's the first thread I've tried to help on for ages because it's just painful. And guess what. It still is.

thats in your mind,have more confidence ,i called you an arse because of your comment why wouldnt i ,i didnt disrespect you,i missed your post as i previously admitted, it was spot on in the pressure fact and what apart from dippys addiction i was trying to ascertain,but whilst replying you miss posts ,more so with the new system

firstfreelander · Dec 13, 2015

So in between arguments the general thoughts are worn seal on pump then? Would it be better to replace the in tank fuel pump as the one at rear wheel was done about a year ago ? Thanks for the advice btw

I know/knew nothing about what you guys were talking about at the start of the thread - but I do now, so thanks for enlightening me, I seriously did find it interesting !!

I do think you 'engineer types' do tend to count cogs and say there's a ratio - full stop - period - fact. Which of course is true. When it comes to opinions that may vary (however slight that may be!) its a recipe for melt down.

I hope that's not offensive.

TBH Diesel - those same places that slate LZ for arrogance, rudeness or what ever - generally end up degrading to the same levels themselves - except without the knowledge base. They do also tend to clear because facebook, or what ever, doesn't really care about historic records so it all gets washed away when the next person asks what size tyres they can fit on their rims.

Getting back to the OP.... I have no expertise or previous knowledge of your problem. What I can tell you though is that those rear wheel lift pumps can fail very quickly - especially if you bought an aftermarket one. Reading what's been said though, would a leak back test on the injectors and a compression test on the engine be the way to identify what's going on? Also would a diagnostic plug in not say what sort of pressure is being generated within the fueling system and therefore show if the HP pump's OK?
