Help, what did I do ?

OK sorry, I thought the Freelander would still crank but not start.

OP, Have you tried pulling out an injector to see if it is injecting fuel? Hope I'm not being stupid here but I watched big Ed China checking his injectors by putting each one in turn into a plastic bottle. He was also able to watch the spray pattern at the same time. Can't remember what the car was but I think the problem he had was a faulty loom.

I think that's correct for the Freelander's immobiliser.

It's possible to check the injector this way. However extreme caution is needed due to the ridiculously high fuel pressure. Pressurised diesel at 18,000 Psi would take a finger straight off, or blind an eye very easily.
 
As I said earlier in the thread yesterday we cracked the injector pipes and it only dribbled out of injector 1 and nothing from the others.

Fingers crossed for new Cam Sensor in 2 days time.
 
Not trying to be funny here, but you have said you used a water based de-greaser with the battery still connected, have you checked all the fuses? Just a thought.
 
Unless anyone has a better idea my next more is to test the fuel rail sensor and go old school with a resistor to fool the ecu into thinking the fuel rail sensor is working ok.
 
I don't understand why fuel was only dribbling out of one injector. If both fuel pumps are working wouldn't it come from all of them? Even with just the ignition on? I just popped a leakback connector out and the fuel came out pretty quickly with only the ignition turned on.
Can you hear them, especially the one under the bonnet?
 
2004 Facelift has only ONE pump outside the engine its under the rear wheel arch and it is running.

Its quite simple the ECU isn't sending power to the injectors hence no fuel.

The trick is to work out why.
 
As far as I can see from my RAVE manual on the Td4's control system, the ECU needs inputs from the crank, cam, LP and HP fuel pressure sensors in order to start (i.e. fire the injectors). Other inputs can have default values substitued if they fail.

I can post up the ECM pinout diagram so you can check the outputs from these sensors with a multimeter if you want. Not as good as a scope, but better than nothing.

Sorry they're sideways - flipping them round correctly is obviously too much to ask of my computer today...

The highlighted bits should apply to you, but they're really for me - I too have a dead Freelander TD4.
 
The face lift 2004 td4 does have two fuel pumps, you have the one behind the rear wheel that you have mentioned, but you also have a lift pump in the fuel tank, if this has stopped working the pump behind the wheel will not be able to pump the fuel to the injectors.
