I have two adjacent ceiling fixtures holding two 40W 48" fluorescent

still other times they need to be rotated slightly in their sockets.
And sometimes they won't go on at all.

What should I check?

The fixtures are at least 18 years old, but do not have the little
starter cans that older fixtures used to.

i'd be checking the ground to the fixture(s)
