have you got water ponding in the bottom of the tank?
if it's been standing with a part full tank then the water in the air above the fuel condenses on the cold inside wall of the tank and runs down the side and ponds at the bottom of the tank, just where the fuel pump draws it out of the tank.
no matter how good the mlll it won't run on water.

then again if you've cranked it a few times you'll most likely have cleared it and I'm talking bollocks. again.
just ignore me.
