#1143 of 1226 2002 grand am timing cahin
Jul 10, 2012 (1:25 pm)
I own a 2002 grand am se w/2.2 L
ecotec engine-- It has a timing chain, not a belt. After a lot of research on the matter, and a rebuilt engine, this is what I have learned.--There is a manufacturing defect, in that the chain is too tight and does not get enough oil. Mine broke with only 59,000 miles, and an oil change less than than 2,000 miles old. I am a careful driver, I don't race, or make jack rabbit starts. The best thing for any Grand Am owner to do is have your timing chain replaced before it breaks, and takes your engine down with it. Also, on the new timing chain, the nozzle for the oil is larger. Why hasn't there ever been a recall on this? This problem is too well known for the manufacturer not to be aware of it.
#1144 of 1226 2002 Grand Am security system
Jul 10, 2012 (1:40 pm)
It's me again with another tidbit for you Grand Am owners--the security system is also faulty, as well as the timing chain(on another post of mine). After many hours of research, I learned that the security system is also faulty. When my timing chain blew, and I had my engine rebuilt, I found directions on the internet on how to by-pass the security system. I had my mechanic do this, and lo and behold, my security light still stays on! Many times I have had to sit in a parking lot and wait 15-20 minutes to reset my security system before my vehicle would crank. Not to mention the several times I had my car towed to the GM dealership due ti it not starting, and they would call and say I owed hundreds of dollars, but they just didn't know why it didn't start before, but now it does. I even bought a new battery thinking that was the problem. Research "faulty security system" for your Grand Am, and see what you get. That's what I did.
#1145 of 1226 Dangerous Passlock/electrical issue
Jul 10, 2012 (8:11 pm)
I have a 04 Grand Am GT and I was driving down the street today and when my car went over a small bump in the road, the power locks and tachometer/odometer went haywire. Repeatedly locking and unlocking. Seemed to resolve itself and then about a block down the road the car completely died. No power steering, electrical, couldn't even engage the hazard lights. So then I put it back in park and restarted the car and it ran OK except it was a little rough for about a mile. Very dangerous being that this happened in the middle of the road. Wondering if it is safe to drive now. I know this has to be an electrical issue but I wonder if it could be related to Passlock. Anyone else have this issue or some advice?

I did the resistor trick and I did get the light to go out but it still not start,but I am writing this because after I did it the starter would not even crank! Same as your problem, so I turned the key to the ON position and waited about 20 minutes then it actually cranked, so the BCM or something completely stopped the cranking ability. It will still not start but at least it is cranking now.

I've been to your website and would love to know if your bypass method will work on a '97 Grand Am where I have to access the wires through the steering column? And will I need the same resistors? (Please say, "YES")
Sep 01, 2012 (7:46 pm)
i am trying to do this bypass, i removed the radio, looking for the three wires, i can only find 2 separate groups of wires, one bundle appears to have fifteen or more wires in it, the other has about seven, the smaller bunch has a heavy yellow wire and a thin black wire, don't think these are the correct wires, the larger bundle appears to hook up to the ignition switch, where do i find the wires i need to cut, are they by chance located under the steering column?

The three wires you are looking for will go to the Key lock assembly at the end closest to the driver. The rest of the wires going to the ignition switch will be routed to the end of the key/ignition assembly nearer the front of the vehicle. They may be routed around the tumbler assembly underneath.
The three wires you are looking for are 20 Gage or smaller... probably the smallest Gage you will find in the bundle.
You may be better off trying to access these wires at the BCM, as described at:

I don't think the 97 grand am uses the BCM for it's passlock system, but you can find out if you get hold of a service manual and look up the wiring diagrams for the "Security" system.

i've been reading all the posts about the passlock. my 04 grand am has all the symptoms except it won't crank at all. when i turn the key nothing happens. i've checked the battery, relay and starter and they all work fine. i'm wondering if my problem is the passlock or possibly something else

The passlock system DOES NOT keep the starter motor from running. The passlock circuitry detects if the lock cylinder has been tampered with, and if so, it sends a signal to the powertrain control module, which then stops the fuel injectors from operating.
