Still having an issue that has gotten worse. 2015 t4 with 55 hrs and 560 miles

Still having an issue that has gotten worse. 2015 t4 with 55 hrs and 560 miles. Randomly won't start unless I hold throttle to floor and crank about 10-15 seconds. Even cycling the pump several times before cranking doesn't work. Runs perfect once started. Other times it starts great. Pulled spark plugs today they looked good changed them anyway and it's already done it once since then. Did the fuel vent mod right after it was new and the clear filter I put inline still looks brand new. Never been in water deeper than floorboards. Any ideas?

  • Still have the filter in the tank

  • Check valve backwards?

  • No it's correct I just extended the hose and rerouted it.

  • Works fine after started?

  • Yes once it fires up runs perfect.

  • My son manages a kawasaki dealership and he says...its under warranty so make them fix it! He said most likely a fuel pump issue. He is a wiz at fixing stuff so I trust his diagnoses!
