PATS = Passive Anti-Theft System
Must have correct key to start engine.
Ok, on re-reading your posts it seems you installed '98 engine minus electrically operated IMRC, keeping instead the old vacuum operated one along with old PCM, ignition module and wiring harness. PATS should not be a problem.
I can only suggest you double-check wiring integrity and connections since some harnesses were plagued with faulty insulation and your's has now been handled a couple of times. Also the ignition module could also be a likely suspect.
Suggest you get Haynes manual re wiring diagram, although they are a bit of a mish-mash of european cars info which is very confusing.
Good Luck.
