Frank - The battery was flat - Richard got one of the ROY POW chargers that started the car immediately - of course it needs a drive now to charge the battery.
Small enough to fit in the glove box - and great to carry around just in case you have a flat battery for whatever reason.
A drive wont charge the battery fully or anything like. Running the diesel in my boat where I have decent instrumentation unlike the car, shows that it takes a good 6 hours running or more to fully charge a battery. The alternmator rating is a maximum. It rarely if even reaches that level and rapidly falls off as the back emf of the battery rises. 2 hours in and you'll do well to be getting 10 amps out of a 60 amp alternator.
Did you not have any ECU issues with the car after allowing the battery to go flat?
I recommend Optimate or similar.
