My 2006 200 DFI optimax ran fine all day, after I got home I flushed the engine out with fresh water, it ran for maybe a minute and then it stopped. Tried to start it and just wouldn't start. Checked kill switch, it was ok, still have fire, checked the air pressure on the rails and it was over 60psi (gauge went to 60). Does anyone out there have any ideas what might be my problem? I check the fuel filter, getting plenty of fuel to the filter housing. Do ya"ll think the fuel pump went out?
