cdt diesel starting problems - Page 2

If the cam sensor checks out then do an injector leakback test - you may have a dodgy injector, although it would be rare for a relatively low mileage car.

it could be an injector as that sounds the same as the problem 2diesel's had, check out this forum for details

i had problems with CDT difficult to start after short journeys and it was the in-tank fuel pump, as advised on this site. problem worse when low on fuel. i.e. less than 120 miles left according to computer. changed pump insert (£90ish) and fine now. (i am a relative newbie and wondered why this suggested solution hadn't come up yet, as it was one of the first things i'd picked up from using this site.) also did plenum drains as mine started cutting out after right turns, ...water splashing into ECU..
absolutely brill now...what a car!

Reason no-one has suggested it Steve is that the symptoms don't fit the intank pump failing. Normally this causes the engine to stop or refuse to start at all when the tank level drops to below a quarter full.

If your car was difficult to start and you replaced the intank pump and all is fine then if you have an under bonnet pump that may well be worn or non OEM because the cars with these fitted will run for months with a failed intank pump, as long as there is enough diesel, despite what alot of people will tell you.

If you don't have an under the bonnet low pressure pump then your intank pump was displaying a rare type of fault for this unit.

A leaky injector (or 2) is very common also with your symptoms
Do a leakback test .

You may have a high pressure pump problem or the fuel pressure sensor has failed and the ecu thinks you have a high pressure problem. Plug it in to a T4 if know of a garage that has one locally.

A leakback test will not guarentee that the injectors are OK, there are other problems that can occur, my CDT was cutting under load, leakback was ok, had them repaired by Lynx diesels all ok now
