    With inline pressure guage installed psi at 36 with key on. Psi decreased 0 psi with key off. Removed fuel rail found #3 injector dribbling with fuel. Replaced injector; starts and runs great. Thanks for your help!

    DF300 Hard Start

    Very low residual pressure (5psi) after 5 to 10 mins. If I cycle the key a few times or crank 2- 3 times it starts and runs fine. No codes

    DF300 Hard Start

    2019 DF300 has hard start/extended crank. Replaced low/ high pressure fuel filters, high pressure fuel pump, and fuel pressure regulator. Fuel psi is 37 running. When engine is stooped psi slowly sinks to 5 psi. What hold psi in fuel rail? I see no leaks.
