    EFI 150 warning buzzer, water in gas

    I got some water in my gas tank. Buzzer went off. My other tank was empty so I added some new fuel to it then drained the fuel filter and pumped in the new gas with the primer bulb. Do I need to change the plugs as well. Motor wont start. It fires at times and tries to start but it's almost like there is still water keeping it from starting. Would the plugs be fouled do to the water? Or do I need to keep priming the bulb to get the new gas cycled through?

    Thanks,
    Darrall

    Darral:

    Any water in the fuel system would need to be purged. This includes the fuel rail, injectors, VST, pumps, lines, etc.

    Plugs would probably need to be cleaned/dried, as it's likely they're heavily laden with water at this point.

    This is not something I would leave for long at all- water causes nearly immediate corrosion to fuel system components, injectors, cylinder walls, piston rings, bearings, crankshaft, ETC.

    Recommend IMMEDIATE "hands-on" assistance from a Certified or Master Technician.

    Don,
    Thanks for the reply. I'm heading out after work to work on the motor. I talked to mechanic last night and he told me what to do.

    Thanks,
