Not having the best of luck with car atm, had boost pipe replaced recently (diagnosed according on here)...., however still been chugging and slowing me down intermittently since. Yesterday gave up on me completely on dual carriageway, almost as if in limp mode and eventually cut out. Tried restarting a few times, some it worked but cut out again after 2 or 3 seconds.

 

Had it on ramps all afternoon yesterday and mechanic said the high pressure fuel pump has gone, with £720 being the cheapest part I can find... Does anyone know a cheaper alternative such as reconditioned? I know might be a long shot as the mechanic said its pointless as they don't recondition too well, just wondered if there are some different opinions on here?

 

P.s., the Ford part number is 1541974... 2010 Focus 2.0 TDCI

I'd rather buy a genuine used HP pump cheap than spend hundreds on a poorly 'reconditioned' one personally.

Though in all honesty I'd probably change car instead.  If the pump has dumped metal filings into the rail then the injectors won't last much longer anyway.

Yeah its just finding one thats the problem...

 

What do you think the likelihood is with the metal filing problem, and if so how would that be diagnosed?

 

I spoke to a 2nd opinion diesel specialist and he said he is dubiois to the original diagnosis, based on the fact that he has sold 2 of those pumps in the last 20 years of trading. He did mention to get the injectors removed and continuency tested. The original mechanic did say he checked them but didn't mention how....

If the pump has worn internally, that does usually create filings.  Best way to diagnose is to check the filter and filter housing.  The shards show up like gold dust in there.

Common rail HP pumps don't fail often.  I've never had one fail on my own cars.  Though I am surprised at just 2 in 20 years at that specialist.  We probably average one or two a month on this forum.

Injector continuity will only tell you if you have a totally dead injector solenoid.  A single failed injector shouldn't cause the issue you're having though.  And that should also be easily picked up by the ECU's diagnostic system.  I take it there weren't any OBD codes?

If that's the case that failure of these pumps is rare (and I don't know either way), then why not just pick up a used one from a scrapyard ?

I would think a used one should see the life of the vehicle out unless you're very unlucky and it will probably  cost under £100

I will have a look, struggling to find one atm...

 

Regarding post above, the code readings linked to cams

How did they come to the conclusion that the fuel pump was the issue?  

Sounds more like a faulty crank sensor or a slipped cambelt.

Do you have the exact fault code?  I'm guessing it was cam/crank sync?

Im presuming because its not drawing fuel from the pump onwards? He did mention he tried a manual pump or something to rule it out... 

 

I will chase him up for any codes, I doubt it will be the cambelt as was done by him not long ago

If that was the case there should be a low fuel rail pressure code stored.

If not a low fuel rail code what would you suggest?

If the code is for cam/crank sync I'd suggest checking the crank sensor wiring for any damage.  If no damage found then replace the sensor.

If still the same then belt covers should be removed to check the timing.

If there really is no fuel from the HP pump then I'd double check the low pressure side is full.  There's no tank pump on these so the smallest crack or pinhole on a LP pipe means all the fuel drains back to the tank.  If the LP side is full then I'd probably swap the fuel pressure regulator before condemning the pump itself.

Thanks for reply

 

It was indeed the HP pump, fuel filter removed, lots of particles. 

 

Managed to get a 2nd hand engine for £400 and take pump and injectors off that to swap. Mechanic did say when he got fuel tank off it was horrendous with particles, so flushed the full system through.

 

Since picking up at the weekend it is randomly stalling at times and running a bit rough. Doesn't like idling and crawling in 2nd/3rd, so need to take back to garage.

Been running car since last post but has been a bit rough since fuel pump replacement... took it back in garage and it was one of the injectors not sealed properly.

 

The smoking and fuel smell has gone away since refitting injector, but it still acts weird on start up, where it is quite noisy and now cold weather here struggles to start. I have to rev it to stop it cutting out.

 

When i drive it it seems not as powerful, and judders when in higher gears at lower speeds, such as crawling in 2nd. Always does it in gear 6 around 50mph onwards too.

 

Any suggestions?

Hello, did you solved the problem? I have the same problem with vibrations after pump replaced. I suspect pump is not timed properly....
