I've been having a mysterious time diagnosing a Kubota RTV900, she blows white metallic burning smelling smoke, knocks, and generally is way down on power. I narrowed it down to what I thought was an injector by cracking open each line while it was running. It died on two injectors, but didnt do anything on one injector. I swapped it with another known good injector (I have a spare blown d902), and I couldnt get the lines bled after multiple attempts. I went backwards in troubleshooting, bypassed the fuel tank, filter, created a Home Depot gravity gas tank, and the injection pump only spurts out 1 of 3 bores.
I removed the injection pump, disassembled it, and I do see what might be a few parts not moving correctly, but in general everything looks fine, no broken springs. After comparing rebuilt parts costs vs a reman pump, I ordered a reman pump and we'll see what happens in a few weeks.
