03 TD5 fuel issue - Disco struggling to start, intermittently.

I hope that you'll fix the issue based on all the previous inputs cos it really seems like pump or injector washers thing... but there's another thing which can cause difficult start, not so common but possible, cheap and easy to fix, that's the fuel temp sensor which is in the FPR, you can't really check it without tester to see it's output cos there's no warning protocol for it but if it fails the management picks up a default value and the symptoms are difficult start(it's the same NTC sensor with the coolant temp one and not some brilliant construction)

just something to be ruled out not necessarily the issue here

Any movement on this??

I am having similar scenario, except that mine was fine one day, and then failed a couple of days later sitting in the driveway.

Hi all.

Replaced fuel pump yesterday in an effort to correct low fuel starting problem - and discovered the old pump was caked in a weird black algae-like gunk. Is this diesel bug? Could it be the source of my woes? It was black and had the consistency of wet snot. Sorry for the visual.

Thanks all,
Aa

This is probably carbon , when the fuel inj copper washers leak it allows combustion gases to get into the tank via return line , replace your inj washers .although the wet snot may be algae

Hello again.

An update on my situation:

Have replaced the fuel pump, the injector wiring loom, and just this morning finished replacing the injector seals. Car is back together and seems to be running well, so far.

Once again I have quite a lot of diesel in the tank, so will have to wait a couple of days before I can really tell whether or not my hard work will reap dividends.

Cheers for your help everyone,
Aaron.
