I think the first thing I would do is have the battery tested for broken connectors, check all the ground cable attachments, have the alternator tested and the connecting cables between battery, starter and alternator.

The battery could have gone bad from sitting and isn't giving enough power for the sencors to read or something. I would deal with the battery first and see if that solves some of it.
