The AFM is the Air Flow Meter and is between the intake air filter and
the rubber "S" boot that attaches to the throttle body.

Yes ... a bad ignition switch will allow cranking without supplying
spark or fuel.

The ignition switch has multiple contacts and one of the failure modes
is to allow cranking (key turned all the way to the right) ... but
opening the contacts for "Ignition on".  When the key is simply in the
ignition on position (not all the way to the right for cranking) the
ignition on contacts "Make" again.  Sometimes, but not always, just
gently turning the key until the starter engages (not turning the key
hard to the right) will allow the switch to function properly.
