Part of ongoing issues, when key is in ignition position just before cranking I can hear a loud hissing noise that appears to be down near alternator.

Could it be the self priming fuel system?
Would that then imply air getting into system overnight?

It's the opposite side to FBH.

hello did you ever find out what the hissing noise was near the alternator because my td4 is making a hissing noise now.

Start by looking at the various intercooler hoses

most likely fuel from the hp pump returning back to the tank, (its normal)
