Does sound like dead battery . Sometimes cheap / flimsy jump wires are useless and can be misleading when not connected fully . Or if battery is really knackered , jump start may not work .

Thanks for your info battery is fine think the ECU could be the problem as keys can open and lock the boot but not the doors the rear lights work but not the front

Battery showing 12.7 v there is no difference when you turn on the ignition with the ECU connected or not so now beginning to think water has got into fuse box or ECU as car ran fine was loaded onto a trailer then transported over a 100 miles in heavy rain and wouldn't start to come of the trailer

Battery is fine . You mention transported on trailer , nothing to do with the shunt fuse ?

Recommended 10/ 15 mins for shunt fuse if it makes any difference
