Wonk crank unless its jumped at starter solenoid

[8URZR1]

Who's very savvy with lightnings? Truck won't crank unless I have key on and jump start it at the starter solenoid. It just started today. I drove it and runs fine. Am I missing something? I just replaced it with two starter solenoids today. Any help would be appreciated. 903-714-6075 Hector

Check to see if you have Voltage from your signal wire coming from you Ignition switch, to the starter relay, if you do check the ignition switch, and the wire going to your fuse panel box from the ignition, I had the same problem as you on a 99 f150, and it was a loose wire going to my fuse box, I could bang on the fuse box while trying to start the truck at the same time, and it would start.
