My theft light is flashing rapidly. The engine cranks but no start with either key. This happened after I replaced the clock spring. I rechecked everything and coming up empty. Any ideas? Hoping I don't have to tow it to a dealer.

 

What year is the truck? Haven't you already posted this problem?

 

I posted a no start problem after the clock spring was replaced. I didn't realize the theft light was flashing. The problem appears to be related to the anti theft system and not the clock spring.
The truck is a 2001 F150

 

PATS module might be going out, and maybe not recognizing ur chipped keys

 

..or you unplugged or accidentally damaged the pickup coil around the key cyclinder while you were in there....

PATS problems almost always involve a tow truck and a dealership repair bill. Good luck.

That's for sure. She got hooked up this morning, just waitng for a phone call and bill.
