    No pre-start oil pressure

    Thanks. Very helpful. I’ll follow up with your suggestions. Since posting I had a mechanic in to service injectors. His opinion was that the starting oil pressure was normal and commented that most engine wear occurs at start up; it is possible to install an oil primer but few bother with it.

    No pre-start oil pressure

    It's 210hp. I assume these engines are supposed to show at least 30 psi pressure before starting to ensure there is adequate lubrication for start-up. Could anyone confirm this?

    No pre-start oil pressure

    Cummins marine 6BT 5.9. With ignition on before starting, oil pressure gauge wiggles at 0 psi and low-pressure alarm stays on. Upon starting there is a 5+ (?) second delay before pressure goes to 60 and alarm goes off. Has anyone else had this issue? What should I look to as a cause for this?
