Sorry, I mean to say check the wires from the battery to the "other" connections. To ensure that none are chafed or loose at the connections or kinked.
The PATS system is Passive Anti Theft system. Later models have it. If you have it, you would see blinking red light on the dash when the car is locked. If you don't have the red light, chances are you don't have the PATS system. Apparently, the PATS system can sometimes cause a "no start" condition.
