No crank

No. There are three separate igntion switch contacts, IE three separate circuits having to do with starting.

1--"Ignition run", or IGN 1, traditionally dark blue. Comes off the ign switch, feeds power to the cluster, runs THROUGH THE BULKHEAD and goes to the ballast resistor, the IGN terminal on the regulator, and on 70/ later cars, the blue field wire on the alternator, electric choke, if used, and on some cars, a smog doo dad or two. This is hot ONLY IN RUN, NOT in start

2--"Ignition bypass", or IGN2, traditionally brown. comes off a SEPARATE switch contact, THROUGH THE BULKHEAD, and only goes on place---to coil + side of the ballast. Hot ONLY in "start" and supplies "hot" power during cranking for a hot spark in start

3--"start" signal, traditionally yellow, comes of a separate switch contact THROUGH THE BULKHEAD and to the "push on" terminal of your start relay. Hot ONLY in start, it's what makes the relay/ starter operate. ON CARS WITH the "reset button" relay for the seat belt interlocks, this wire is in series with that relay contact, and should be bypassed.
