Car Forum / Land Rover Cars / March 2008300tdi Not starting
Help My def 300 tdi has decided not to start. It turns over ok, The immobiliser light goes out ok when key is in the ignition, so I assume it is a fuel feed problem, there is fuel in the filter so I think it must be the solenoid that shuts off the engine is not working. I take it that I can check the voltage at this point by a connector or such like but I dont know where to find the thing. or which colour wire to check. any guidence would be greatly recieved thanks or even links to photos Eddie >Help > [quoted text clipped - 9 lines] > >Eddie The wire is the only one, on a Defender, that goes to the injection pump. If you can't find the injection pump then perhaps it might be a good idea to get a manual. Check for power at the solenoid when the ignition is on. It is not uncommon for the immobilser to fail in such a way that allows you to crank the engine but sill does not supply power to the fuel solenoid. The wire could be loose and have fallen off !!!  SignatureMarc Draper The shut off solenoid is located on the drivers side of the engine near the top - easy to access. Although it's a single wire which should have 12volts on it, might come from a 3 pin connector block. these connecters work loose and can fail. Try waggling it with the ignition on and you may hear a slight clicking as the solenoid activates and closes. Usually easy to fix and if the power is lost completely from the circuit, you can remove the actuating mechanism from the solenoid. But of course the engine won't stop on the key and you'll have to stall the truck!....k > >Help > > [quoted text clipped - 23 lines] > -- > Marc Draper > >Help > > [quoted text clipped - 15 lines] > If you can't find the injection pump then perhaps it might be a good > idea to get a manual. I know I shouldn't but that made me PML. :-) M > Check for power at the solenoid when the ignition is on.

On the wiring diagram i have it shows this as a white wire, but none that colour in site! towards the rear of the pump almost underneath there is a black wire that connects on a spade connector, does anyone know what this does? >> Help >> [quoted text clipped - 20 lines] > the rear of the pump almost underneath there is a black wire that connects > on a spade connector, does anyone know what this does? The wire on the spade connector is the feed for the solenoid, although I've only ever seen the wire in white. This connection is notorious for giving trouble so give it a really good clean. You might even consider cutting of the spade connector and fitting a new one. As the wire is black, trace it back and see if it's been spliced somewhere - maybe a previous owner had the same trouble.

The round connector with the 3 wires on top is the EGR with system The black wire with the spade connector located at the back of the pump is the one you want.
