Turbo Diesel Issue Diagnosis Please.

[Daviewonder 533 3 Cars]

Hello all

 

I have a 1.9 Turbo Diesel which has suddenly developed an issue. It hesitated as I pulled into my parking space one night and I switched it off without thinking too much about it. The next morning I started the car without issue but the injector pump is now very loud. it also has no power, sometimes when you push the throttle pedal down the revs dont even raise. Other times the revs raise but there's lots of whiteish smoke and loud tapping from the pump.

 

Any ideas please as this is my daily and I'm new to diesels.

 

 

Cheers, Dave.

what is it? could be a knackered pump.

s*itroen Synergie, people carrier, XUD9 TE, Bosch powered but semi-ECU controlled if I remember correctly.

Sounds like it may have jumped out of time, check the timings correct on the pump pulley first. If not like Welshpug says, the pump could be f***ed.

Hope it's not a knackered pump

 

It was fine and it happened very suddenly, does the pump slip out of time much on these engines?

[Strictly_Derv 34]

Not usually but from your description it does seem like it or the pumps buggered. You can pick up another pumper for under £50 and give it a cheeky tune whilst it's off

Really? I thought the bosch ones went for a lot more?

[Strictly_Derv 34]

No, for the pump on it's own they go for around that on 306OC. Have you checked it's not getting air in the fuel? Does it miss fire at all?

[Daviewonder 533 3 Cars]

doesn't seem to missfire, primer is nice and firm.

First thing to check on this would be the lift sensor on Number 4 (iirc) injector. This gives feedback to the ECU and pump in regards injection timing - When these go (or become disconnected) you get the symptoms you have described.

 

PS - Topic back from dead!

If it has the small filter in a bowl on the head, whedn did it last get changed?

 

I changed the pump on my old STDT when it started to struggle on hills & feel under powered suspecting the pump was dead but in the end it was the filer than needed changing.

 

They have a short service life compared to the bigger filters iirc.
