So, bleed the return fuel
line because thats the new age way to bleed diesel
engines, providing they identify as a diesel engine
otherwise we may need to get in touch with their inner feelings to ascertain that they don't have to run if they feel they are being judged as a diesel when infact they identify as an electric engine
and don't want to run on fossil fuel because that is part of global warming which was debunked and changed to be "climate change" which covers any climate event, so I can noe understand why the poor old engine might be reluctant to fire up.
