Problem with pump learn

[andz327]

My van seems to ne an anomaly especially being a 130 that's done 323,000mls, runs with cheapo prv for 120,000 mls and still not had a computer near it, snaps timing chains but doesn't damage nowt,,,,,,, so cant give advice comparing with me auld beast if you see what I mean guys

Only possible issue is putting a genuine prv in with a cheap scv and that then blows the prv which wastes money, not aware of any other issues tbh, injectors are tdci so if in good order i can't see them failing and over fueling but then if the scv isn't regulating the fuel reliably (hunting) it is possible for the pcm to compensate but still i don't know of any evidence of over fueling.
fuel rail pressure can't exceed 1600 bar so it's all good i think

Someone else may know better tho, i just base what i know on keeping things sweet using correct parts etc, not really studied what 'may happen'

I will say that in your case you've passed the injector pilot learn so i think quite possibly you've bought a good prv. Was this from eBay or pf jones?

PRV bought from Perry's direct.
SCV from PF jones throught their ebay shop.
Van isn't hunting after parts where replaced. Before replacement, Pump Learn was also failing. And while in heavy traffic, engine was losing power, no warning lights on the dashboard.
I guess I'll just wait and see what happens now, possibly buy small laptop so I can always have IDS handy to check what is going on if any issues occurs..
thanks very much for your advice, guys.

PRV is just a mechanical valve nothing fancy. But SCV is a bit more complex.
Svc is the one I wouldn't recommend skimping on. Either a genuine or trusted source for that like pfJ

That's where I got it from and look what happened...

Try doing the learns again now, its a bit cooler out side so it might pass. N

I respectfully agree and disagree

Prv is very important because the length and thread depth and spring tension and washer depth need to be as good as the original, the copied ones are just all plain wrong and don't allow the rail pressure to be correct at all which causes the van to be a bitch to start and no pilot learns etc

Only 2 possibilities here since he bought the prv from Perries Ford.

Scv from pf is poor quality (i don't associate pf with poor quality items tho but don't know) or there's an error ie leaky gasket or return pipe etc causing fuel problem.

Could be low voltage or other things, could be egr valve (i was getting eml for egr but i remember mine passed the learns so I'll lean away from that for now

Why not buy a genuine scv from Ford or denso, fit it, try the learns (might need to check the prv is still intact too, if the problem persists then you can sell the scv on here, if the problem is fixed then see if pf will honour some sort of refund?

To cover myself i have to say it may not be the scv but we've all seen it over again

Should this 2 day conversation not be in technical support getting board now

[Punto443]

Yes, it should be in its own thread I think

Now, where are those lazy moderators????????

[loot]

I'll sort it

[adam75pl]

Tried it again this morning, no success.
Drove it for couple of miles, no new fault codes, it seem to work fine.
I'll get another SCV from Ford (Ouch!) and see what happens.
If anything, I live 5 Miles away from Martyn.

Martyn says that DTC is harmless. Doesn't affect anything.

If that is what he said then he'll be correct.
