Answer
Hi Bobby,  When's the last time you had your LR tuned?  Air filter good?  Fuel filter ok?

It could be fuel/air problem. Clearly, the starter is working, as is the ignition switch.

My first thought was the MAF sensor:  "The MAF sensor is an electronic sensor that sends a signal to the engine computer, which then uses the measurements to help calculate fuel delivery and spark timing".  One of the signs that the MAF is failing is hard starting.  Eventually, engine stalls will occur.   You could clean MAF by removing it and using a quality MAF cleaner.  Remember, this is a very sensitive part, so caution is always required when manipulating it.

The worst case - a failing fuel pump and not enough fuel present to ignite.

SO...tune your vehicle (new spark plugs, air filter, fuel filter), clean the MAF, perhaps run some injector cleaner too, then see if starting improves.  

A qualified LR mechanic could attach a diagnostic device to determine where the difficulty is, check the internet in your area for independent LR mechanics.

Best of luck,

Land Rover Discovery. I've had most of the common mechanical failures, altenator, water leaks, wiper failure, door/hinge problems, roof rust, floor rust, loads of electrical problems. Remember, I'm not a dealer or a mechanic, just an owner like most of you.

Owner of a Discovery. I've had many mishaps with our Disco but I still like this vehicle. Talk to a fellow LR owner instead of a dealership rep. I'm not in this for the money. I'm just an owner who wants to help others.
