Fuel Filter / Pump??

StompToWork

One for the experts out there. 03 Mondeo 2.0 Tdci. Recently been labouring and chugging a bit under load, and at high revs it cuts out with the "glow plug" light on the dash flashing. Diags at my local garage reveal a p1211 among other codes that I can't remember but suggested low pressure at the rail and injectors.

Seeing as I had all 4 injectors refurbed (by a reputable diesel injector refurburer!!) not even 35k miles ago, the consensus seems to be that the fuel pump may be on the way out.

Two questions :
1) Is there any chance it could be something as simple as the fuel filter clogging up?

2) If it is the pump, how advisable is it for a home "mechanic" with a fairly basic tool kit to attempt? Is there always high pressure on the rail, even when the car isn't running? Am I mad to even consider attempting it?

Ta.

Firstly its quite possible one or two injectors are gone again depending on the diesel you are using and also weather the job was done one hundred percent in the first place.

Its very simple to diagnose faulty injectors its only a matter of attaching a set of leak off bottles run the car and see how much diesel comes out the leak off.

As for changing the filter its worth a go but i wouldnt hold much hope of it fixing your problem but you have to start somewhere.

Removing the fuel pump wouldnt really be a diy job there is a special tool used to hold the fuel pump timing gear if the timing moves you will end up having to remove timing cover and reset all your timing.

My advice would be get a proper diagnostic done determine if the injectors are faulty again if the injectors are ok you could be looking at a faulty fuel metering valve in the back of the pump which could be done at home.

Thanks for the reply. I thought I was being a little bit ambitious alright. One of those things where the car isn't worth putting too much repair money into (feckin' lemon of a motor), but I can't afford to buy at the moment, so I was attempting to be frugal. Looks like I either pay for the repair or just drive it 'till it stops and cross that bridge when I get to it.

It wouldnt cost much to test injectors half an hour will show if they are leaking or not then take it from there.
