Hi Simon
No warning light flashes when temperature gauge drops - it just cuts out. However, once it's cut out and I keep turning the ignition, if the temperature rises the car will eventually start and if the temperature doesn't rise it's a no go. Unfortunately the car just won't go at all now. Any help - much appreciated! Thanks Keith |

Have you tried easy start ??
If it will start then you might have a fuelling problem. When you turn on the ignition but NOT try to start the engine you should be able to hear the underbonnet fuel pump running. Also if you listen inside the back of the car just above the rear seat you should be able to hear the tank pump running. They should both run up to 30 seconds before shutting off. No sound means no fuel to the engine. If they run but the engine will only fire up on Easy start then you could have leakback at the injectors or low pressure from the high pressure fuel pump. In addition a poor electrical contact on any of the fuel pressure sensors will not allow the engine to start. ( Or even a defective sensor will have the same effect. ie. no start. ) PS. Don't be too hard on your starter motor or you will kill it. After a few attempts to start the engine allow the motor to cool off a bit. |

Never heard of a diesel flooding.... Pretty hard to foul a spark plug!
Sounds more like the ecu thinking something is wrong but then wouldn't a warning light come on?

I think you should pursue T-Cut's suggestion: an intermittent connection to the coolant temperature sender or a faulty sender. Simon.

A faulty temp sender won't prevent the engine starting.
Even if the ecu thought the temp was very low, it would still start and the automatic idle stabilisation would keep it running (albeit possibly a bit unevenly). I'd check all the earths and also remove and inspect the ecu for water ingress and corrosion of the multi plug contacts. Also do likewise with the relays in the under bonnet fusebox. (K46 & 20) Ron

Also spin engine over fast enough to overcome leakback if the injectors are the problem. After that remove and replace all electrical connections in case the problem lies there. |

I think that was my point!!! It's the plugs that foul on non-oil burners .... how does that happen with an oil burner?

Could try the diagnostics mode and check the temperature as seen by the CAN (?) bus.....
