2003 Grand Am shuts down while I'm driving

My 2003 Pontiac Grand Am shuts down while I'm driving. Everything else will work, lights, radio, windows...it will shut down while I'm doing 60mph on the highway. I've taken it in to get repaired and because it is not reading a code, mechanics are not sure what is wrong with it. I have had the fuel pump replaced and crank shaft sensors and it is still doing this. I need some advice on what could be making my car shut down with out warning. It will go days with out doing it and then shut down several times in one day. HELP PLEASE!

SOURCE: When driving on the roadway,

2000-2002 Grand ams are notorious for having the most faulty passlock systems ever installed. You are experiencing a passlock failure. When the cars stalls on you, check to see if the "security" light illuminates on the dash board some where. That would be a 100% indicator that its the passlock

Look at this link i found when i had my problems. Read up on symptoms and fixes. 1 of those fixes eliminates all parts of that passlock system and you will never have to worry about it again.

This could be an anti theft security issue. This happens all the time in GM's. The anti thefts are known to fail and cause the car to not start, stall while driving, or start for 1-5 seconds and then die. A good indication that the security is failing is if you see a light on the dash that says SECURITY or a picture of a car with a padlock thru the window.

SOURCE: My radio is not working

Get a new radio. Or an aftermarket radio with $180 adaptor. Sucks, but the radio ties into the security of the car, which may be effecting your starter. Sorry, these are probably the only options.

My 2003 Pontiac Grandam will shut down while I'm driving and it has to do with the security system


The security system is called Passlock. And yes it will turn off the fuel injectors when it starts to fail. Go check out this link, should help inform you about how the system works along with some ways to get around it.

Pontiac grand am 2004 3.4 6cylinder installed brand new battery altenator & starter all good car started took it for test drive everything shut off car wont start. lights radio still come on


Sounds like the security system activated or the ignition is bad. If you have an alarm installed remove it. If you don't then replace the ignition switch after checking all fuses in the fuse panel. There is one that can blow and will give you this symptom.

Ok I have a 2003 pontiac grand prix that started messing up yesterday. It'll cut off while I'm driving, sometimes it won't even start at all and if I try to crank it the starter starts...


Sometimes the anti theft security system that came on these cars start to fail and the car can literally turn of the starter and/or injectors. Next time this happens, check to see if there is a light on the dash that says SECURITY. This would be a dead give away of the problem. This link describes security symptoms, and possible DO IT YOURSELF solutions. http://vatspasslockpasskeysecurityhelp.yolasite.com/
