I am afraid it sounds like an earth strap hasn't gone back on properly when its been reassembled and then ECU has fried itself.  The constant fuel pumping is a good sign of a knackered ECU. Ebay or a scrappy for a replacement.

It mite be worth seeing if you can borrow a "good" ECU off someone to try on yours and then you'll be sure before you spend out on another ECU !

Replace the erath first though or you'll end up frying that one as well :)

Its almost definitly blown, clean up all the battery/starter/alternator leads especially the gearbox earth with sandpaper till they're proper shiny and refit.
If it still floods the engine, go and buy a new ECU!
