Thread: Disco 2 Will Not Start

Its not very likely that the crankshaft position sensor sensor has failed, as the ones in the TD5 seem to be very reliable . It could be loose or the leads not properly connected though. Without having replaced one but knowing how they work, I suspect a replacement sensor would work well enough to run the engine but could possibly cause difficult starting.

Have you checked for oil at the ecu connectors? Oil at the ecu is a common cause for all sorts of problems as lots of sensor wires are in the same connector as the injector wires, down which the oil travels.

the engine will start with a new sensor without puting it on t4,

if you cheak everything and its all ok,

if its a man dose it push start ok?

if it dose push start ok, but wont start on the startermotor, the starter motor has failed,, even tho the starter still terns the engine ok it is making a electro field(as the cps and the starter are very close) and stuffing up the sensor and wont fire the engine, wev had 2 td5s with this prob now, and yes it took days to work that out

What actually is it doing... or not doing? Does it turn over at all?
