I have a Kubota RTV900 that I am having issues with......it will start up, run about 10-15 seconds then die......turn the key off and wait a few minutes, and the same thing happens. I have gone through all the steps listed to bleed and prime the pump even though I did not run out of fuel....and I cracked the lines on the injector pump and watched fuel pump out as I crank it, so I am not convinced that it is a fuel injector issue......is there a relay that could be causing this? What is the starter timer relay that people have mentioned and what does it do?
