Start (injection) permission is given when pressure is over 150-200bar. I don't know what precise shut down limit is, I believe around the same. 8bar is primer pump pressure, ok I would say. If there is no fault code about low pressure, reason is somewhere else. Fault code will store some engine parameters when triggered. You may need SDS to pull all engine codes, universal reader won't neceessarily do it right.
