I purchased a b5200 with 3 cylinder diesel. I bought it not running and after some troubleshooting i adjust valves then it ran. I had it running for about 1/2 hour then it died. So i got new filter and cleaned tank and new fuel. Bleed system and got fuel to injectors. I got it it start and stall a few times. It only ran for few second and very little rpm. I did have it running longer on wd40 for over 30 sec anyhow. I put new lift pump in it and pulled lines at injection pump. It is pumping fuel out of all 3 ports but im not sure if it’s enough. It seems either the injection pump isnt strong enough or the injectors are clogged. Any thoughts or does anyone know how high fuel shoots out of injection pump. With compression release it spurts about 6-8” in the air. When release isnt pulled it’s a 1”-1 1/2” in the air with a steadier stream. Any help would be great thanks
