    NEW PUMP?

    Ok so I took my ski to the ealer last season cause it stopped running. they told me it was the fuel pump, So I got another pump from wayniac and starte to take the old one off today. After spilling gas everywhere I decide to plug the pump in when it was out of the tank to see if it still worked. It spurted gas out of the top nipple! Could it be that the pump is weak and doesn't have enough pressure to run the ski or do I now have an extra pump? I'm going to put the new pump in just in case. Any ideas of what me up? oes anyone know if these pumps just get weak or do they altogether quit? let me know Thanks!!!!

    It would help to know what you're working on.

    By stopped running what do you mean ? If you have fuel issues on a DI ski you want to be sure to check compression.

    The '03 manual says the DI fuel pumps put out 105 psi. Maybe the attachment will help... Ron

    well it cut out all day and it wouldn't go faster than 15 mph then it would kick in and run great. Then it stopped running altogether. I took it to the dealership and they said it was the fuel pump. Also I read on here one time that you need to bleed the fuel system if you take the pump out that can't be right can it?

    Alright I put the new pump in and tried crankng it over. It sounded like it wasn't turning too fast and the battery went dead after about 7, 2second cranks. So I'm going to recharge the battery and hopefully it will start cause if it dont they dealer was wrong!

    Ok charged the battery cranked it over several times and nothing. Pulled the plugs and they were bone dry not a sign of gas on them I dont think the thing is getting an ounce of gas to the cylinders and now I have no idea what to look at next maybe pull the line off the filter and see if gas is getting through there? any ideas?

    does the pump pressure up when you install the lanyard?
    if yes, check your fuel injectors,
    if ok move on to the air injectors under the aluminium injector block directly under the fuel injectors, also check all electrical pins in the injectors.
    if all ok then do a pressure test on the air compressor pump
