2016 rz2 won’t engine cranks but won’t start

[cberard]

Boat cranks strong. Batteries full 12 v
Remove fuel line at engine lots of fuel
if I pour a bit of fuel in cylinders boat starts for a minute
I think injectors not opening allowing fuel to cylinders

I had this issue with my boat. For me it was the camshaft shaft position sensor plug was not fully clipped in. There are two, one on each bank at the back of the engine by the exhaust pipes. You can buy injector signal test lights from harbor freight to confirm if the injector is getting a signal to open. https://www.harborfreight.com/11-pie...set-97959.html. Unplug one of the wires going to an injector and plug in the light that fits the clip. Turn the key and watch for a light, if it does not blink as I said likely a camshaft position sensor.
