I'm beginning to think you may have a bad ignition switch. That could cause both of your problems. If you turn the ignition switch to the on position, do you have power to the ballast resistor and coil +? If so, try cranking the starter by jumping at the relay or starter motor to get the engine to crank. If it now starts, and still doesn't with the key, the ignition switch is probably bad. I've seen a few of those switches melt down by in internal short/ground or a grounded wire in the steering column. If you don't get power to the coil with the key in the on position, start tracing back toward the ignition switch to see where the open/short is.
