Try swapping the two yellow relays under the seat, I have some you can try if you send me some info another quick thing to do unplug the injector harness at the head and clean that plug, another thing is do the same with the crank sensor, it’s...

If that's the case then why doesn't it loose pressure over night? If an injector leaks fuel would the oil level not go up?

Maybe @sierrafery might have some helpful ideas. I'm reasonably confident he will need some live data to be able to help though.

Thank you for your replies - Ive looked through the videos and to be honest I havent considered a fuse being part of the issue. I plugged in my pscan this afternoon and ive attached the readings - I just crank her over and then took the readings...

There are other videos in the series.

I am nowhere near being an expert but from what I have read on here you need to check the readings from the cps when starting.

I can plug in my pscan initally

So my local garage has replaced the injector seals and copper washers on all of the injectors. When the looked at them they said that they noticed diesel leaking from injector number 5 so there was definitely an issue there. I think I have...

Well please let us all know how you get on.

To be honest mate I dont know, but the garage a pretty insistent that its that as it has the symptoms of a td5 that needed injectors they sorted a while ago. Im going to hire a nanocom (£40 from ebay) so that I can do a better fault code check...

Thanks fo the advice Discodevon - the TD5 is a dec 1999 with 85k miles. Ive changed the crank position sensor and the injector wiring harness and cleaned out the ECU connectors (there was a tiny bit of oil in there) and there is no difference or...

Thanks for the comments. Yeah I get that the fuel pump maybe ok if its noisy but it just doesnt feel right - but im going to leave it on anyway. I managed to connect up the PSCAN yesterday and it says that amongst other things "high speed crank...

Yeah Ill check both of these things. Regarding the air in the system I do think that this may be an issue, as I changed the fuel filter housing and as my fuel pump was noisy I bit the bullet and put on a genuine one. However that was screaming so...

If changing the starter and the wee tab then the battery all fixed the problem (albeit temporarily), my money would be on a electrical issue rather an injectors. It will be interesting to see what a Nanocom says.

Have you cleaned the earths? I had similar symptoms on my Tdi recently which were sorted by new battery earths to the body and chassis. My previous Td5 disco had difficulty starting due to a leak from the fuel pipes from the fuel pump too which...

Hi Everyone I have to be honest and I'm a wee bit low today...Landy has certainly been testing my mental health! I've worked on her constantly since I got her (2000 TD5 90) about 5-6 years ago. Pretty much a total rebuild initially and then a...
