    2006 STX-15F Possibly Starved For Gas Please Help

    The jetski is very hard to get running and will not stay running. I took a video of the injector flow to see if this is normal. Also when you give it full throttle the injectors stop spraying. Any ideas on what this could be and a possible fix?

    Thanks in advance

    they look fine enough to run it, how old is the fuel, i had one with old fuel that would start and stop eventually run but not well, put fresh fuel in it and it was like new, full throttle stops injectors firing on start up

    when you pull 100% throttle is is supposed to shut down injectors, its so you can clear a flooded enginel, nothing to do with starting isuues, also EFI engine dont need throttle to start

    replace the fuel in the tank with fresh fuel if you are not sure of its quality , replace the plugs , check comp and fuel pressure, check spark with spark tester

    thats for starters , dont worry about injectors

    Just use a t fitting, that is how you have to test anyways. For the fuel pressure I usually just test at key on. The pump runs for a few seconds if you just bump the starter button.

    fuel regulator direction and vent line

    So I noticed today the fuel line going from the fuel rail goes to the side on the regulator that says out? My lines are run fuel pump-rail-regulator-tank. I can't see what the other side say but wondering if this is correct as i still cant get my ski to run right. note i bought it not running like this so someone may have switched it at one point on accident. Also, I noticed the line on top of the pump housing, I'm guessing is the vent i cant blow through but can slightly suck air through?

    Make sure it's flowing the correct direction, the regulator goes last.
