Did the 'fully reconditioned' pump have a new diaphram and seal?

Jim

Yes new diaphragm, seals and Ecu which includes solenoid and sensor.

It's in ford commercial main dealer tonight now for diagnostics on it cold in the morning.
Last chance I guess as no body else can figure it out.

Sounds like oil starvation has killed your engine from the bottom up mate, best to replace your engine rather than a rebuild

Jason, after a bit of messing does it run normally?

It's not likely to be oil starvation. Had new oil pump twice.

Yes after it coughing and spluttering into life and then running rough for few minutes it clears and runs ok. Pulls well.

Don't forget it starts first turn of key from cold everyday and if you don't touch the throttle for a few minutes it stays clear and will rev and pull off no problem.

To make it run rough from cold you have to give it revs as soon as it starts from cold.

Also drives pretty well generally once cleared.

Oop sorry bud , that reply was me not looking at the date of your first post and not realising we're now 30+ pages down the road

Could it be drawing a bit of air up at the fuel filter side, when left over night the fuel is running back and when you start up and leave it ticking over there's enough fuel in the pump to run at tick over long enough to suck the fuel back up without air getting to pump, but if you start it up and rev it up its sucking air and fuel up into the pump side and making it run rough

+1...!

Certainly sounds like this sort of thing.

It does I agree but what about the loss of compression type noise you hear in the video after it does to start with?
That's what has confused everyone.

Also bear in mind it's been run with a can of diesel direct into the pump thus eliminating the filter and associated pipes. It was exactly the same in the morning.

Had Ford main dealer on the phone this morning and they suspect an ECU fault. Probably the only original part in the van now i reckon.

They are going to look into the wiring and connectors on the loom and check for sure.

Should know more later.

[Jason_app]

Ford main dealer IDS picked up p0252, pump data mismatch code.

Ive been told that with a cps error there also that the fault is most likely in the loom or ecu.

Ahh...that'll do it...
