rx di problems need help please

[crxdi]

Hi im new here and i could really use some help. We have an 02 rxdi that we just got the other day. It barley runs and has a hard time starting in the water and at full throttle will only do abour 2100 rpms. I pulled the plugs to find that one is clean and like brand new and the other is black like it should be. the craft sat for about a year without being used. I have checked the compression and it is fine Im thinking that the one cylinder is not getting any fuel. could a dirty fuel injector be the cause? I dont know anything about these direct injection motors. and also does anyone know about how fast this ski will go when i get it fixed. also it has a maint light that wont reset, but we had the dealer scan it and he said there was no recent codes and he reset it.

yes a dirty fuel injector could very well be the problem. try putting some fuel injector cleaner in it and see if it helps any(you can get it from autozone for like 5$). however since u said the spark plug was like new the injector might be more than dirty. see if adding fuel injector cleaner helps and if it dont youre probably going to need a new fuel injector
