Give us more info,

Cranks and no start?
No crank?
Tries to turn over?

Just narrow it down, start at the battery make sure terminals are connected TIGHT. Then check the battery voltage, Should be somewhere close to 12.68V. Then you can turn to the starter, but it could be ruled out if we had more info. I mean if it cranks but no start it could be alot of things. Basically start witht the obvious/easiest no need to make things hard on yourself. Check the primary ignition, will be a plug right on your coil pack, assuming its not coil over plug, not sure witht the 99s.

Like i said, check that stuff and give us more info, it will be easier to diagnose.

sounds like your PATS isnt reading the key right/something is wrong with the system

IIRC there is a tiny battery inside the PATS key.
After 11 years it probably is dieing.
Ever notice how a dieing battery seems to regain some life after sitting a few hours ?
Time for a new key.

IIRC, the pats is an RFID chip. It is powered by a radio freq sent by the computer to a ring around the ignition.

I had this issue once.

Reset your computer. If it does it again try flipping the key over.

Mine went away on its own. Its possible the transceiver is going bad, or the computer isn't getting all the data off the key.

The dealer is the only one who can deal with PATS effectively.
