to blled the mfi system, put ignition on, take plugs out and press down on the metering flap , you should hear all the injectors give a little squeek, if they dont all do it, keep pressing it till they do, the turn engine over and fuel shoud get thrown out of the spark plug holes,
also as rodney says it might be cold start valve as they do tend to fuk up, but it should still start if you feather throttle a little bit
