Is the key in the column? They sometimes did that when the switch was out of adjustment. It can just be moved up or down the column to adjust.

Instead of relays, you could simply use two diodes. Diodes will have to handle whatever the average current is on the device it is feeding but will work fine.

Excellent idea, these should work https://www.mouser.com/datasheet/2/4...ries-63289.pdf
I'm likely going to use relays, available at Auto Parts Stores. It's an automotive application.

Use smaller diodes like a 1N4007 to power one relay.
I know this is an old thread but I thought I'd add my 2 cents. When I converted my '64 Impala to TBI 10 years ago I only remember having to tap into the purple starter wire (used the "R" terminal on the starter) for a CRANK signal. I recall metering out which IGN wire/circuit stayed hot even while cranking. Pretty sure even TBI requires 12V IGN and CRANK for starting. I would buy a new ignition switch and ring it out, it sounds like the current one has a bad contact. You might even be able to disassemble the old switch and clean it up.
