That's a bargain then new pump and you get 1/4 of fuel with it can't be bad.
I don't get it!
I am guessing the sensor/float built into the pump was playing up??
Hope you have not bent the arm. Ball ache if you have.

Slightly off topic i know. But would not be a problem with Claws SAAB that, there's never owt in it.
My mate from Brum had a SAAB brand new, hardly ever got him to his place near me in France without an electrical failure. He's got a P38 DHSE now, much more reliable
Poor Claw, out of work, no cash for fuel, ought to have got a decent old diesel that he could run on used chip fat

Yeah and he is a good bloke worked all his life paid his dues. Makes it even harder to take when certain people are driving round in Mercs and Beemers paid for by our taxes.

Evening all, I'd like to pick your brains once more if I may!
Car used to have trouble picking up speed, would have to floor it then it would realise it was alive.
Didn't always happen, but it stopped for ages.
Last week it started happening again, I feel like it was just after o drove through a puddle. The majority of the time it's fine, but I'll come to a junction, roundabout etc and it won't go anywhere.
I replaced the hose from MAP sensor to manifold recently with some 3.2mm id hose, so it's not this.
I did have a powerbox fitted, a dieseltuning.nl one (came with the car) which I disconnected, got better for a day then the fault started happening again.
I kind of think it is the throttle potentiometer, especially because ive had condensation problems in the car in the past, but I'm not sure.
No black smoke out the back either, what do you guys think?
Thanks!

Yeah i know went off on a tangent. MAF on the turbo diesel is not used in the same way as MAF on the petrol version. The air does vary with revs but that part of fuelling is controlled by MAP sensor. It's difficult to explain and i got tied up so deleted it.

I might be able to throw a bit of light on these diesels.
The 2.5 diesel came in two versions. 94 to 98/99, then from 98/99 to 2002.
The later engine had the egr's & the maf. The pre-98/99 diesel didn't.
The EDC for the earlier engines started AMR. The later engines started MSU or similar.
The AMR diesel ecu doesn't have the egr's or the maf , but the later MSU ecu does.
The ecu's can be swapped between both the early & later engines.
Garages in the past didn't recognize this difference & fitted the wrong ecu's.

EGR came in on MY 1998 models. Not wise to swap ECUs diag will show up some strange readings.
I could be wrong, but I think Ricks post has a typo......

SHOULD IT READ:

As the first line says can be, but the line under says garages used to fit the wrong ones - the two lines contradict eachother.....
I can only assume they can't be swapped .

Nephew had a 1997 manual non EGR i did a head change a couple of years ago. Head cracked. It had been chipped. Should maybe have been early EDC but would only respond with late EDC in BECM. Some readings were transposed. The minus 38.8 degrees IAT preset for the late EDC EGR ECU was listed as fuel temp and the IAT was around what the fuel temp usually is. Car ran well but diag was all to cock. Left well alone.

It wasn't a typo. & nothing show's up on diagnostics either.
The MSU is indeed a MSB, I got that part wrong.
I've seen the 96 models with the MSB ecu & the noticable difference is very slightly higher revs on tickover.
Place the AMR into the later engine & it can drive not as good as it should. But nothing comes up on diagnostics. Programming etc is normal.

Wammers,
Are you talking about the early early EDC.
On the diagnostics, you have the choice of early EDC & late EDC. Both the engine i'm discussing here come under the late EDC on diagnostics.
The early EDC doesn't require an EMS code, & these are commonly known as pre preduction edc.

Maybe but the chip that had been fitted was obviously not right for the ECU. It worked fine but some readings were transposed. As i said it ran ok so left it alone. It was a manual which is a different ECU to the auto.
Sure it does. But it has not been chipped with a chip for the EGR ECU. This one apparently had been. IAT temp varied but the fuel temp was always -38.8 degrees which is the preset for IAT on a EGR ECU.
It was a one off. I am no aficionado of ECUs but this thing was strange. With the wrong readings in the wrong places. But ran well so did not bother with it too much.
