Last week I re-installed my Duratec engine some 5 months after removing it, when I tried to start it I had the exact same symptons as you've described not priming, sparking and ECU dead, thought that I must have blown the MBE whilst jumping off, as battery was dud. Looked through some pics I had taken whilst removing and noticed 1 cable I'd forgotten to connect, once connected fuel pump primed plugs sparked and hey presto life. Might be worth checking all your connections, mine was the purple cable in the pic located under the throttle bodies. Good Luck
