Diesels require more power to turn them over because of the higher compression. If it will start with a jump and will not start from your battery, that sounds like the battery is not producing enough cold crank amps to start it. It could also mean that the oil is too thick for the temperature where you are. Make sure you are using the recommended oil weight for your temp range if you are in a cold climate.

Years ago I ran a fleet of tractor trailers and logged some diesel experience from that. We put block heaters on them that inserted a heating element into the water jacket. You plugged the heater into an electrical outlet overnight to keep the oil warm and they would start OK in cold weather. It takes a lot more battery to start a diesel anyway and when they get cold it becomes worse.

Don't own a Land Rover. I drive a Jeep Wrangler that will qualify for antique license tags in two more years. :-)
