2006 Yamaha T50 fuel issue

[carolinaskiffman]

Hi, T50 issue, getting fuel to the injector rail(pulled hose hose and cranked over to visually see fuel coming out) but not getting fuel to injectors. I'm getting spark to plugs(visually inspected that), but no fuel? Seems weird, I put a new fuel filter for the injector pump in, and the pump must be working because their is fuel coming out the hose that goes to the injector rail? Any help would be great.

Thanks...

Check fuel rail pressure to see if in spec.
If it is the the injector screens maybe plugged or injectors just not firing

Not sure on how to do that, but will look in repair book on that. Didn't see any breakdowns of the injectors?

Basically send out your injectors. They will give you a before and after flow record. They could be jammed up with all sorts if they have been sitting for awhile, or if you ever had water in your fuel.

Well that what it was, Injectors, all 4 were froze. Got a set used that the guy cleaned and put new filters in for free. Traded some computer work for his parts/service so all was good in the end. Anyone know how often the fuel injector pump filter needs to be changed, and the injectors cleaned and new filters?
