How many miles?

When was the last time you changed the fuel filter?

How old is the fuel pump?

Have you test fuel pressure?

What type of plugs are you using and how old/miles are on them?

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!).

How long does it take for the fuel pressure to leak off after it is pressurized?

I am sure you have tried this, but disconnect the battery for an hour or so to see if it resets the ECU... also does it have any OBDII codes?
