Multiple Codes...HELP!!

So I'm driving to work. My Freelander SE, 2.8l 6cyl, starts to lose power then stalls. The engine cranks, but won't start. I check with my code reader and come up with the following codes:
P0171, System too lean, bank 1
P01319, Misfire with low/empty fuelDrive Cycle c: Signal out of Range -above
maximum
P1473, Variable inlet manifold motor2. Short circuit to V. Batt.
P1471, Variable Intake Manifold - Bank 1, Always Closed
P0128, Coolant Thermostat (Coolant Temp Below Thermostat Regulating
Temperature)
P0174, System Too lean, Bank 2

At the time, my low fuel light had just come on. I checked and I have spark at the coils from the plug wires, and the linkage on both manifold valves are ok. Should the motors be able to be turned hand? Also, I do not hear the fuel pump when I turn the key forward. I tried the fuel pump reset but it was ok.

I should also mention the warped head, but that has not been a problem with engine performance, and my starter has been acting up previously with intermittant starting.

ANy ideas? I don't know where to start...

check it's all going round and cam belt has not snapped, then providing battery is good look at fuel side of things

fuel pump, fuel pump relay, fuel pump fuse,

That's where I was going to go next. Checked all my fuses, they're good. Any Idea which relay it is? And what are the chances of changing the pump without dropping the tank? HA....
