Duster won't fire in cranking position.

If you have a wiring diag. start tracing.

Could be bad or miswired ignition switch.

Jumper from battery to start side of ballast resistor, if it starts and keeps running it will give you some where to start

Thanks! I briefly thought about the ignition switch. I do have another one I can swap out of the old steering column.
