*update*! Well me mate came over and found a fuel line he easily unclipped (without even jacking it up!). Siphoned (sp) about 5 litres of petrol/diesel out of it. I then had it towed to the petrol station and brimmed the tank with diesel this time (

). Stuck about £40 in and all was good, she starts and ive driven about 2 miles without a problem!!!
Cheers guys for all your help!
