if you remove the switch or plug from under the filter put a container under it get someone to switch on the ignition and checvk the flow it should be fast and smooth,patent pumps often fail very quick

Hi James,

Correct me if I am wrong, but is not the filter on the TD5 the low pressure side of the pump, Is it possible for the Hi Pressure side to fail and yet it still pump fuel thru the filter housing?

Cheers

it is,high pressure is straight to the fpr from pump, its only the low pressure your checking, but if its a poor flow high pressure pump isnt going to be fed well

Yes, I get that, but is it possible for the LP side to flow OK, but the HP side to have a failure due to the pump or the FPR?

of course it is ,you can only prove the other with a gauge few have those, most times failed or blocked pumps show at filter,but not every one

before ripping the motor to bits try bump starting it. I did seals pump and all kinds to get mine running. It turned out to be a dodgy starter motor that was spinning fine but a was arcing and messing with the crank position sensor, it turned over fine and wasnt slow or anything. Reconditioned starter motor and it's been fine ever since.
I've seen other folks have this problem with a td5 too.

Hi Alan,

First thing ,as you are already doing , Get either a fully charged and healthy battery on there. The TD5 does not like a low battery voltage when cranking.
When you have the battery, make sure you can hear the fuel pump running.
As BB has said the Crank sensor failing can stop the car.
How far did you drive it after picking it up from your mechanic?

Cheers

Okay Neilly, brand new commercial battery fitted. Engine started, a little bit slower than normal, but no significant issue, no smoke black or white, the engine ran from 11:26 to 11:48 (22 mins by my fingers) and then just stopped.

I managed to find a new garage, not too far away, who has a basic analytical reader. He said he has never used it on a td5 before and it's a fairly basic machine.

I have arranged for it to be put up onto a recovery flatbed and taken into said garage on Thursday for a Friday appointment. Hopefully, he will be able to check for anything untoward in the coolant and, if I'm very lucky he might get some information from his analytical thing

. So it's heading in some direction!

Oh Dear,

When it stopped , would it turn over again? if it did was it slow?

But, I think taking it to a garage is the best bet, get a professional to look at it. However if he is not sure his kit will work, I wonder if he has much experience of working on TD5s?

Cheers

Hi Neilly. Yes it did turnover again, but i didn't overdo it. I turned it over a couple of times and it did try to fire but didn't seem to want to start.

No, he has no experience of Td5, but I am told that he is a good mechanic. It's really difficult to understand how problematic it is to get an experienced mechanic near where i live. My usual Polish guy is really good at general motor mechanics, but has very limited experience or equipment. My nearest LR specialist is in Enniskillen, Northern Ireland. The trip for me is about 55 mins and out of the question, for now, on trying to get the vehicle up to them.

That's one of the penalties that we experience for the benefit of living in a less competitive and less expensive Country.
