I don't know what you "should do" but what I would do is track down the purple wire that goes from the ignition switch to the solenoid. I have attached a wiring diagram that may help.

If the truck still has the Neutral Safety Switch in place it could be an issue.

Thing I would check are...

neutral safety switch
wire from ignition switch to firewall, 12 ga. Purple
Wire from the external fuse block connector to the solenoid. 12 ga. Purple
Just make sure they will light a test light when they are supposed to. If you use a volt meter, you may get 12 volts but not enough current. Use a test light.

Make sure you have a good ground to the engine as well.
