Thread: td5 hard starting issue

Can't help with your problem but the TD5 has a FPR and they can leak. In my experience this didn't prevent the vehicle starting or running, but did use more fuel as it leaked out.
Have you checked the fuel hose near the tank where it runs over the chassis?
I believe they can rub through. If this happens you could be getting air into the system.

Replace the air bleed valve at the fuel filter
Had the same problem on my defa td5 110
Hope it works for you

Check fuel pump, injector seals and copper washers.

Mine had the FPR leak. Never caused it to not start, but was slow. Minor leak. Since I fixed it it starts instantly, hot or cold. Well, instantly after I press the unlock button on the fob. Never used to need to do that. I blame Adrian. Lol.

Yes. It's under the inlet manifold.

Here is a useful link: www.discovery2.co.uk / Workshop / Fuel Pressure Regulator

I had the same issue with my D2 TD5.I replaced the air bleed valve just before selling it.There was some improvement,but I was unsure if the issue was resolved.
I did buy a new fuel pressure reg of Ebay that went with the vehicle,probably the root issue.
Search Ebay,you can buy the seperate regulator and fitting kit,MUCH cheaper than a OEM FPR.

nanocom is showing no codes and reads rpm when cranking
there is very little cat noise when priming
but willcrank and crank with no life like it has no fuel, prime the system and it normaly starts first kick.
its only done 2000km since the filter was changed
it has also been running rough at high load at low rpm and lacking power.
iam thinking its the fuel pump any other possibility's

You may have to replace the "O" rings and copper washer seals on the Fuel Injectors, when they leak you end up with air bubbles in the injector, causing your symptoms, Regards Frank.
