sounds like the crank position sensor is bad.

When working with GEMS vehicles. Never try to locate a misfire by pulling plug leads off - pull the injector connector instead. Otherwise you can blow up the ECU.

Secondly never swap ECUs between vehicles to test them, because both vehicles and ECUs may stop working, and you'll have to have them all reset by a franchised LR dealer (ouch!).

I'm not familiar enough with all of the nuances of the Disco II's electrical / ignition system to say for sure, but I will say that a faulty neutral position switch can usually cause the car to not want to start.

The neutral switch ensures that the car is in neutral or park before it will start to prevent it from trying to start while in gear. Just for laughs you might want to try shifting through all of the gears and see if that yields you any change.
I would guess that the switch would be right there at the shifter and should be easy to fix, you might be able to bypass the switch with a paper-clip or just by joining two wires (all depending on how the switch is configured this may or may not work).

I had problems with my coil pack not long ago and that's also a possibility but it was only causing misfires, I didn't have a no-start condition. Weak spark would also point towards bad wires or bad coil pack(s).

As the other poster mentioned, there's also the possibility that you've got a bad crankshaft sensor. I'm trying to think of how much of a bear that would be to replace...unless I'm mistaken it's sitting on the front of the timing cover. You'd have to tear down the fan / belts, one bolt holds it in, plugs into a weather-proof connector which might be bolted down somewhere as well.

I'd check the neutral safety switch for starters.

Joey,

I believe you gave me the advice to change the crankshaft position sensor. The repair seems very straight forward, but my workshop manual tells me that I have to "Reset adaptation codes using TestBook" What does this mean?! and can I do it myself?!

Does anyone have any suggestions after changing the crankshaft position sensor, the workshop manual says to "Reset adaptation codes using TestBook" What does this mean and can it be done without taking it to a dealership or shop?!?!
