update, towed it to a local garage this morning after 2 hours of investigating they found it was getting fuel and there was a spark all they could find was there was a signal from the crank sensor to the ecu but nothing back out of the ecu, there conclusion is the ecu is at fault they are saying they can have it sent away to be checked and repaired if there is a fault. My question is does this sound like it could be the problem? if i buy another ecu with matching numbers will it plug in and work i know i will have to get the key coded but apart from that will it be ok?
