  • 150 efi hot start problem

    Hello all. I have a '93 150 efi that will not start hot sometimes. It will act flooded, but is not. Thinking it was flooded, I unplugged the elecric fuel pump. It will start right away if the electric fuel pump is unplugged. The pump must then be plugged back in before the engine runs out of fuel(about 5 seconds). The engine will not do this cold, and will fun fine with no other problems. Any ideas what the problem could be? Thank you, Doug.
