MH-60R APU won't start.

    I'm doing everything in order (it's not very complicated), the APU will start, but then turn off and just repeats. I've probably watched every youtube video out there to follow the right procedure and the issue persists.. Any help will be appreciated.

    1. A small number of users are having this issue. For some reason, the fuel valves leading to the APU are closing on their systems, ending in the APU being starved from fuel.

      We are planning an update to resolve this soon. In the meantime, you may start the engines on BATT Power or GPU, which isn't an incorrect procedure.

      You may also try to perform APU Starts without touching any of the fuel boost pumps nor the APU BOOST switch, as those may be causing the conflict with the fuel valves. In any case, we have a fix candidate in the works.

          Oh wow. I spent four hours watching YouTube startup procedures and was really starting to doubt my understanding. I'm glad I found this forum post. So I'm not officially stupid after all. LOL
