Mechanic told me the compression was low and that is why it would not start - had the power head rebuilt - still will not start - took it back to the Mercury dealer and he now says that the ECU was bad and not turning on my fuel pump - was going to buy a new one and a guy from another bass club gave me his old one and told me to try it - now I can here the pump and it starts foe a few seconds and then dies - has anyone ever heard of this or can steer me in the right direction. Thanks
