    Welcome to the Hulk Terry.

    #1 Did you replace the fuel lines inside the gas tank?

    Did you replace the petcock?

    Was the autocock removed per Polaris bulletin?

    Did you install the fuel pump hoses correctly?


    #2 Is the lanyard installed?

    Have you ohm tested the stator?

    Did you bypass the kill switch?

    Is the battery in good working order?

    How many volts are at the battery WHEN CRANKING?

    #1 What do you mean working pump with mouth????

    #2 Open elec box and remove the black with yellow stripe wire coming from the kill switch from the circuit board. If the ski starts, you will have to choke the engine until it stalls out to shut it down.


    Just because the battery is new, doesn't mean it's fully charged. Double check it's voltage when cranking.

    #1 I need more info from you about this. What do you mean work fuel pump manually???

    The fuel pump works by many + and - pressure "pulses". How are you manually simulating this?????

    Check your pulse hose for any liquid inside (shouldn't be any) and make sure your pulse fitting is clear.

    Also what's your compression on the PTO cyl? (rear)

    No or low compression will give low or no fuel pressure.

    also double check your fuel hose routing.

    Where is your fuel pump mounted?


    Pics will help greatly.


    #2 Did your stator ohm readings fail?

    No, a 650 stator won't work for a 750. 650 uses analog signal while 750 uses digital. (it will work, but will fail eventually. At least mine did)
