Why is that? Would not a lack of vacuum to the pressure switch not allow the
furmace to light?

**** poor design. Look at the inducer housing. Is it covered with
flaking black paint? Guess what...the inside is painted too! The
paint flakes off and plugs up the port. Just popping a wire through
the port will fix the problem but odds are it will come back shortly.
The replacement inducer assemblies are no longer painted.
