OK all, as per lovemygrandam suggested here's the info. My daughter Jamie's 03 Olds Alero automatic trans was doing the same thing as most here. The security light would be "flashing" when she tried to start her car nothing happened, the engine wouldn't turn over and I don't know if the fuel pump came on or not. Sometimes when she was driving down the road the security light would come on "solid" indicating she had a problem and most of the time it would lock her out the next time she tried to start the car. the 10 min reset always worked. She would put the key in, turn it to the on position and the security light would be flashing and after 10 min it would go out and she would start the car.
she didn't turn it to the off position first then try and start it, that would be like starting all over. I found this site and did some reading and followed the instructions posted here, cutting the yellow wire, installing the toggle switch and it's been almost two years trouble free.
Any questions email me.
Thanks Grandam.
PS I should have told you it's a V6 3.4

That faint click should be the relay, I'ed check to see if you get power to the starter when you here that click. I think you have a bad connection on the battery or from the batter to the fues box or a bad Solinoid. You said the battery was new but you loss everything after you try and start the car, then it all come's back when you shut it off and turn it back on, Confussing. it sounds like a power problem ether at the fues/relay pannel or starter solinoid or starter it's self

I have a 2003 Pontiac Grand am. So 4 days ago my security light came on just out of nowhere. I turned the car off and turned it back on and the light went off. Well yesterday I was driving down the road and out of no where my car shut off and i had a time trying to get the steering wheel to turn into a driveway to park it. Would the passlock problem cause the car to shut down like this as well?

No. The passlock system isn't designed to shut down a running car, just to keep one from starting if it's tripped. If the passlock detects a problem while it's running, the security light in the cluster comes on solid.

So what would cause a running car to just shut down like that? Fuel Pump?

So what happens If i cannot get the car to start and I cut the yello wire to see if it will work? Will I mess something up?

in order to cut the yellow wire the car must be running first, if you cut the wire before you start the car the security system indicates a breach and wont let the car start...
Look at the fuel pump, cam or crank senser first.

TriPower is correct. If your vehicle stalled while driving, the fault is not your security system, and you should not mess with the yellow wire.
One of four things is likely wrong with your car
1. no fuel is being delivered to the cylinders
2. no spark is being delivered to the cylinders
3. no compression.
4. the starter motor is not running
 
If your starter motor is not running, you may have a bad starter motor, or bad electrical connection.
 
If you don't have compression, your engine will turn over faster than usual when you try to crank it.
 
If something else is wrong, I suggest you take it to a trusted mechanic. If you are smart, you will choose someone other than a Pontiac dealer. Their prices are inflated, and they aren't as friendly as the Chevy dealers.

Could be lots of things. If it's intermittent, it's quite often very hard to find the root cause.

after months of trying to get this car started , i found a way. after repairing the lock cylinder, replacing the switch and cylinder, replacing the bcm , having the pcm reprogrammed, replacing the fp relay , and other things that i can't remember because there were so many,i still had no voltage at the fp.so i put every thing back to original condition. at wits end i thought i'd try one more thing before scrapping it. i took the fp relay out and with a paper clip i jumpered # 30 to # 87 .
( IT STARTED ) glory be. the security light is still on and now the air bag light is too. wonder if they are related or just coincidence.
