Okay, after replacing pretty much every relay and getting each circuit right, and then changing the ecu's for ones that work, my RST powered 16i, tried to start!!! It fired and started to run a bit badly, but all of a sudden, and it shocked the shit out of me, fuel literally spewed out of the metering unit flap (thank god i had no filter on!) and it covered the whole engine bay!

Ny ideas why?? Im wondering if all the cranking from before has filled the metering unit up with fuel and the car has just forced it all out? Either way, it scared the shit outa me!
