I have a 2001 seadooI have a 2001 seadoo RX DI won’t start. But if I remove the rear most plug and attempt to start it will then start. With both plugs in and all hooked up as it should I have a jumps back and forth around 80 psi but won’t start. When I stop cranking the fuel pressure drops back down to almost zero fast. If I remove the rear most spark plug and then crank it will build 110 psi of fuel pressure and then start. I can then shut it down and not remove the key just push the stop button and put the plug back in and then push the start button again and will start. This way it does not loose fuel pressure but if I remove the key and reinsert the key the pressure drops and won’t start.
