Swap the starters and see if the fault moves.
However some of the older fittings do not like so called universal
starters.

If a fluorescent tube (about 5-6 feet long, one of a pair in a fitting)

Are starters labelled with a code which makes sure you buy a replacement
which is compatible? Do you need a different starter depending on the
length of tube?

We have several fittings in the garage which are reluctant to start (one
or both tubes in the pair) and I want the cheapest solution to provide
*some* light, even if an array of LED GU10s or of CFL bayonet bulbs may
be better or cheaper to run.

Starters tend to be universal these days. cost 53p + vat at TLC, so that
would be a cheap test,
