Also does it turn over? Any clicking? Warning lights on dash?

It did turnover and tried to start, but now the battery Is dead. I am just back from trying to get a new battery, but the shop is closed! :mad: I want a high cold crank battery that one of our colleagues here in Lonyzone recommend :cool:

But, this is Ireland (the West of) and closing times don't always match with the times people are available to buy:confused:
 
I'm no expert by any stretch but usual procedure seems to be start by checking the fuel pump relay by swapping with another non essential like heated screen
 
Crank position sender is another common td5 stopped in its tracks suspect i believe.

Come on folks, somebody that actually knows about this stuff must have some thoughts?
 
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

About a mile. The fuel pump has only been fitted for a short time. It was a spurious unit and not LR. It is very noisy. The original one could only be heard on starting. This one sounds more like a small machine gun. My mechanic, who did'nt change the fuel pump, thinks that it might not be seated in its canister and might not be picking up fuel. But I'm not sure about that.:( Thanks for your thoughts. It now getting very cold and I have no garage, so am giving up for now. I need to check the fuel flow tomorrow just to see if I do have enough flow to the engine?
 
Best way to check the fuel,is get a fuel pressure gauge on the FPR, so you know it is not just low pressure flow. but this may be something you want your mechanic to do.
Plus a noisy , machine gun pump does not sound good.
Cheers
 
As a rough and ready check, you can just unhitch the fuel delivery pipe from the fuel pressure regulator and see if it is delivering anything with the pump running. Obviously, it helps if you know that it is at 60 + psi, but anything at all would be a help. The TD5 in tank fuel pump is a big cylindrical unit and will quite happily work if it's not 'seated' in the sealing ring at the top, so I'm not quite sure what your mechanic means.

Another thing that goes wrong with TD5s is the ECU. in the course of 60-70,00 miles I have had two go wrong on me now such that the engine will turn over but not fire. I'm getting more ECU failures than I am flat tyres. In both cases the ECU was failing to deliver a signal to the injectors.

I was looking at a utube video this afternoon which says that failing washers in the injectors can cause very noisy pump. I can't understand the correlation, but it is an excellent video which describes the way the system works. I need to watch it again to see if I can gain a better understanding. o_O

Hi Alan,

Any chance you can post a link to it please?

Hello Neilly. I have posted two utube video. I have them in the wrong order, but I'm sure that you will be able to sort out the two. I really do need to look at the explanation for the whining fuel pump again, to try and find out how the fuel pump whines. :D I have just looked at washer replacement kits for the td5 and was amazed to see the price range :eek: Some come with copper washer and "rubber" o rings from about €5 and they go up to about €55!

I know that you get what you pay for the the difference is incredible. Any suggestions?
 
Hi Alan,

I put your name into a D2 owner who also has starting issues. Have you looked at the Starting issues for a D2 that are shown on youtube?
Although you may find it is all not applicable , some of it may be useful.

Cheers

I can't remember if I replied to your post before, but really do appreciate you help. I've been "chatting" to Neilly and have found some very interesting utube video on the fuel system and replacement of the injector washers and o rings which, I understand, can also cause the symptoms which I have experienced:( it's at times like this that Landyzone really comes into its own:cool:. However, I am trying to eliminate the less expensive possibilities, before I get around to looking at some of the options that a number of Landyzone soothsayers, who may well be correct but inevitably many times more expensive :mad:, have suggested!

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

Thanks for that James. That's the practicle sort of suggestion that even I can follow o_O. I have no garage so it's going to have to keep until after the school run. 'Really appreciate you thoughts.
