'02 GT - cranks but no start after battery replacement
 

I have an '02 GT that has been parked since November-ish. The battery died over the winter, so I replaced it with a new one. There are about 52k miles on it - no other issues or running problems but now, it cranks and doesn't start since putting in the new battery. My 'Theft' light does go off after cranking but when I turn the key back off, blinks rapidly. Does this sound like an issue with the factory PATS anti-theft system? Neither my key or the spare works. Looking for ideas?

Time to check the basics. Fuel and spark. If there was a pats problem the light would blink rapidly with the key in run
