Replaced the ignition switch and the truck would still not start, so I took off the starter again last night. I now can get it off in minutes, I've done it so many times. With the starter off, placed a wire from the battery to the large connector on the Solenoid. Turned the key and once again nothing happened. Pulled the connector that goes to the small cable off the the solenoid, this is the cable that goes to the key switch. Shorted this small connector directly to the battery and the starter turned. Apparently, I have a problem with this small cable that goes back to the key switch. I have no wiring diagram, so will have to try and trace it back. Also, not sure how the key gets it's power. It appears I either have a problem with the power going to the key or the cable from the key to the Starter Solenoid. At least I narrowed it down.
