Wanted. 300tdi injector pump.

oos_ya_daddy · Jul 4, 2012

Hi.
My defender manual just failed its MOT on emissions.
Apparently its overfueling. (Goes like sh!t off a shovel though)
So I have been told that I need a new 300tdi injector pump.
Apparently EBay ones are often not of the best quality, so I thought I would ask you guys for help ?

or turn the pump back……..

oos_ya_daddy · Jul 4, 2012

Tried that. Its turned right down so that its pretty much undrivable and still failed.

I got one, came from a perfectly running 300tdi with 126 k miles. Yours for £50. I'm in Southampton. PM me if interested mate.

Find it hard to believe!
How about a good run to clear the sh*t out

sible88 · Jul 4, 2012

£50 is cheap

Dr_evil · Jul 4, 2012

put in injector cleaner first and run it on veg, that'll get it to pass

Put the tester up someone else's exhaust, that usually works ;-)

You say its wound back, how are you doing this? By turning the diaphragm or smoke screw?

Or collier on back ;-)

Im not sure to be honest. Its the garage doing it.
I will ask him.
I am tempted to have it back, get some guidance from this forum on how to tune it down and put it in for a re-test. Its obviously in the garages interest to fit a new fuel pump £££s

Dr_evil · Jul 4, 2012

by emissions do they mean the smoke output or the contents of the smoke ? you should only be tested on the smoke output shouldn't you ?

Freelaner · Jul 4, 2012

smoke or exhaust?

Dr_evil · Jul 4, 2012

Well the contents of the exhaust fumes, I thought that was just for petrol and derv was just visual

Freelaner · Jul 4, 2012

ah, tiz a different kettle of fish wi doozles

oos_ya_daddy · Jul 4, 2012

The reading that was over was something like 4.5% or something like that ?

Choppertrash · Jul 4, 2012

Is (or was) the pump on factory settings or did you (or someone else) tweek it?

If you can, put it back to factory settings, and go from there. When did you last change the air filter?

Choppertrash · Jul 4, 2012

Yes the garage will want to do the pump, as they will do the belt, probably tell you that you need the tensioner upgrade etc etc..........probably not much change from a grand with a recon pump.

oos_ya_daddy · Jul 4, 2012

Garage said it had been tweaked on the diaphram - They put that back to standard.

Then they wound down the fuel screw untill there was no power in the engine at all.

oos_ya_daddy · Jul 4, 2012

Choppertrash. You have PM. I will call you after I finish work. I presume the pump you have is the throttle cable type as apposed to fly by wire ?

Is putting a new pump on within the remit of a reasonably skilled DIY mechanic ?
