John.jr - 2/8/2018 22:17 #1 there's no screen #2 in first picture, yes fuel from bucket #3 were would I test pressure at? #4 not sure on miles #5 governor has a 10r-xxx part number, assuming it was replaced at some point, doesn't look too new. #6 truck does idle low around 600 rpm guessing without looking possibly lower Check valves were replaced, supply and return lines were also replaced. I did take a video of the clear return and supply hoses from low to high rpm no load, not sure how to post it here. I could email it if you don't mind Here's a picture for fuel pressure port. Low idle should be closer to 750-800 rpms. (this adjustment will also provide a slightly more governor spring tension, during cranking) = helps move the rack bar in the "fuel ON" position, when ignition key is turned ON. Don't worry about a video, once a person confirms fuel pressure, set low idle closer to 750-780 rpms, retest/restart/crank, and if necessary, pull valve cover and watch rack movement(as mentioned earlier), and even take long screwdriver (while engine is running, at idle) and move each individual injector's fuel rack, to the "fuel ON" position (causing a fuel knock) then watch return sight glass/hose for extreme bubbles. Is this hard starting, only a problem once EACH morning, or EACH time the person cranks the engine; hot or cold?
