Ok so on my 85 Blazer CUCV, I have no working accessories that are powered by the ignition. The starter does not crank when I turn the key. Nada. The headlights, turn signals, etc all still operate. If I unplug the starter relay and hook up a jumper from the positive to the purple output wire that goes to the solenoid, it will bump over. I took this to mean that the ignition switch was bad. I popped off the plugs on the switch. I have 12v juice at both of the blades on the connectors where the red wires go it, one on each connector. I tried hooking a jumper up across the connector from the red wires to each of the accessory outputs and nothing.

Should I still replace the switch? Any ideas? Is there something else that could be my problem? This is my daily driver and between this and the water pump it has been down for two weeks now, I finally have a day off to fix it and I need some help.
 
Check to make sure you have 12 volts at the junction block on the firewall just to the left of the brake master cylinder. If you have no power there then you have a bad fusible link wire down near the starter or the one just off the junction block.
 
is it auto. check the neutral stafty switch at the botttom of the column.
 
id check the nuetral safety switch too. try starting it in neutral and moving the shifter slightly too. so it wont run even with the key on and you hot wiring the starter?
