1995 Jaguar XJS V12 won't start? Doesn't appear to be getting any spark...

What is your question?

This Jaguar is completely original right down to the factory installed Pirelli tires. Vehicle has less than 14,000 original miles and has been properly stored in the Winter months since new. When it cranks, there doesn't appear to be any spark? The vehicle just continues to crank without turning over. The vehicle has never been towed; I would prefer to hire a mechanic to inspect the issues where it is stored. However, a client advised that I should post the problem here as it may be a simple problem to solve. With less than 14,000 miles, perhaps it's a simple solution?
