TD5 disco wouldnt start today when i went to it.
fuel getting through to engine bay but not sure how to check if through to engine.
dont own a manual so all guess work, any ideas on what the problem may be would be greatfully accepted.

A few more details might help :roll: Will it turn over? Is is turning over slowly or usual speed? Diesel or Petrol?
Is there plenty of fuel in the tank? Mine gets a bit fickle when the fuel level gets low.
Cheers

turns over as normal just not kicking up. vehicle is a deisel.
Did fail to start once before on a garage forcourt but after several turns of the key it started and once it ran lumpy while in traffic but cleared after several seconds. all this has happened in the last month.

High pressure side of the fuel pump (the pump is in the tank, accessed through a round hatch in the boot floor), may be giving up - when you switch the ignition on to position2, can you hear the pump whine ?
Immobiliser - they can play silly-beggars. Try locking and unlocking (using the remote). Mine has done this a few times - normally when parked near to big VW 4x4's :?
Is it an auto 'box - the start inhibitor switch might be playing up. The switch only lets the vehicle start when in 'park' or 'neutral'

Pump does make a sick whining noise now you mention it but seem to be getting fuel through to the engine bay.
Will try the immobilizer though.

Don't know about the TD5 but on the 200 the pump has a fuel cut off switch, my wire fell off giving the same problem.

Steve, your talking about the stop solenoid wire on the bottom of the pump...Td5's don't have Fuel Injection Pumps. Instead they have fuel pressure regulators bolted to the back drivers side of the engine.
If the problem is intermittent then I'd go for the immobilizer first :roll:

Ha ha told you I know nowt about TD5's.
Hope you get it going.

Going at last not sure what it was, tried immobilizer and checked pump and a few turns later it kicked up WOOHOO

The td5 relies on information from several sensors before the ECU instructs the injectors to fire luckily only one of these will normaly stop the engine dead or prevent it starting That is the cranksensor i have known them to be intermittent .The other sensors adopt default values when they fail which generaly allow the car to run but with reduced performance. The sensor is found in the bell housing, ensure the electrical connector is pushed firmly home. When it failed to start was the engine management light illuminated?
if it does fail again unplug the connector and measure the resistance across the two sensor terminals, you should get a resistance of 1365
Hope this helps
