Turned off, won’t crank at all
 

2004 F150
5.4 3V

Replaced my timing chain kit and phasers as a set. Turned on fine and all of sudden it turned off. As I try to start it, the cluster lights up fine, but I get a Fast paced blinking anti theft light, and when I try to start it doesn’t do anything. All here is clicking on the passenger side fuse box, I did repair a ground that got rusted out by the fuse box. Is this a key issue? Or a something else?
