Hi jack, thanks for the reply. I'll try not to bore you with my story, keep it short as i can. car comes back from the paintshop, won't start, no spark, checked all the usual suspects, coil and relays etc etc, searched the net, found how to test the reference sensor and the speed sensor, both checked out o.k. called bodyshop, he then tells me the car sat outside for a few weeks because he had no space (now he tells me). removed ecu from under the steering column, FULL of water!!! made a few phone calls to company's who deal with ecu's. mega money! removed cover, put in airing cupboard overnight, fitted to car today and it fired up!! only on 3 or 4 cylinders. removed plugs and all were wet with fuel, so dryed them out, gave them a quick scrub with a wire brush refitted them and it's running like a dream! it's in my garage now, it'll be kept dry until i get the sunroof drains cleaned out and i think i'll put a new windscreen in it. thanks again for your help, i'm off to get a lottery ticket lol.
