Discovery 3 MY09 TDV6 front end whine under load acceleration
When you say whine does it only occur under acceleration only? If so most likely the wheel hub assembly or some will say wheel bearing but on these vehicles it is complete hub assembly. If you turn or swerve one way then the other does it go away in one direction? If so another strong indication of hub wearing out. If not, and it is a really high whine with acceleration it is also possibly the transmission. I have heard of this complaint before, it's not a sign of failure just a noise that develops due to the pressure placed on bearing under a load. First change fluid and filter for tranny after a good flushing. Replace with high quality fluid and a bottle of transmission seal restore product. Go 1000 miles, change fluid again, if noise is still there turn up radio.
Sorry but just a whine under acceleration isn't a lot to go on. But I'm willing to bet wheel hub. 9 out of ten front end whine complaints is wheel hub or bearing especially on a heavy 4x4 suv

Sounds like a fuel problem, not electrical.
1. Can you hear the fuel pump when you turn on the ignition? If not there may be a broken wiring connection to the pump.(see below)
2. Find the join where the fuel enters the intake manifold. (One is the line in, the other is the return) Undo the joint then turn on the ignition. If fuel comes out, then the pump is OK and you may have just had an airlock.
3. If you could not hear the fuel pump, first check the fuses. If all OK, you will have to remove the carpet in the load space to get to the pump contacts. With a test lamp or a multimeter and the ignition "on" check to see if there is actually power to the pump. If not, it is quite likely the wiring has broken under the vehicle - not a big job to fix it, just dirty and awkward. If you can't find a break, run a test wire from the battery to the pump - you will not need the ignition to test it. - if the pump works, the problem is wiring. If not, it could be the pump itself.

There is a huge coolant
You do not say, but if this is the V8 petrol engine, you probably have a leak at the valley gasket. After 5+ years, this is entirely possible.
Alternatively it may be a failed heater hose.

Series II. Why is diff lock stuck in?
Most likely from lack of use. Alternatively the transmission is wound up where by you need to jack up both wheels on one side to release the load on the axles. Or you can take it on some long grass, sand or other slippery surface, belt it around getting wheelspin and it should pop out. Hold your hand gently against the stick while you do it and it should come free. Don't drive it any further than absolutely necessary on a hard surface to do this because damage will result. You can do it by dropping 2 wheels onto the verge so they slip a bit.
