1998 Pontiac Bonneville will not start

Do you have a multimeter or test light so we can trace power?

With the car in park the big red wire going into your ignition switch should have power going into it. When you turn the key to the start position the big yellow wire will have power coming out of it. Then go to the starter enable relay that is behind the dash left of the steering column. You have should have power with the key in the start position to the yellow wire terminal c1 purple wire terminal c2 purple wire terminal A2. Let me know what you find. The security light isn't on or flashing when you have this no start is it?

You have a problem with your security system that's why your security light flashes and your car doesn't start try doing what i posted say's i also emailed it to you.
