Tried the relearn system
1997 Pontiac Grand Am Se 4 cylinder - Car starts shuts off -battery good, fuel pump working, starts when gas is poured into the air intake. then shuts off all relays seem to be working -tested with a test light HELP
Help accepted yesterday
The security indicator being on is showing that there is a theft deterrent issue causing this car to shut off. This type of problem really requires a special type of scan tool that can read body failure codes such as the theft system. This type of tool can actually go into the theft system and remove a trouble code regarding this problem. This is the starting point for diagnosing a problem like this. The real problem is that a tool like this is $3000.00+ and most people just do not have access to this type of equipment. There is a simple relearn procedure that sometimes fixes this problem. Here is how that is done.
Time required, approximately 10 minutes.
- Insure that the battery is fully charged.
- Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall.
- Leave the ignition switch in the ON position while observing the security indicator.
- When the security indicator turns off, which can take up to 10 minutes, turn the ignition switch off. Wait 10 seconds.
- The car should be operable at this point.
If this procedure does not work you are going to need to gain access to one of the tools I mentioned or have someone with one of these tools properly diagnose this problem. Feel free to contact me with any problems or questions! Good luck!
For those of you who have not done it yet: Mine is a 1997 GrandAm. I warrant what follows for 1997s only, but perhaps yours is the same.
1. The manual says to isolate the yellow data wire through the radio compartment, but I did not have to do that. Pop the top off the steering-wheel housing (it snaps on) and remove the tilt-steering lever (unscrews -- mine had some locktite on it, so be careful).
2. Now remove the bottom portion of the housing (three screws underneath).
3. BE CAREFUL! There are two yellow wires underneath -- one to the air bag, one to the ignition. Obviously, you want the one to the ignition. It is the wire "most" underneath (obvious what that means when you see it) and closest to the driver when he or she is behind the wheel.
4. START THE CAR! START THE CAR! START THE CAR! This is an essential step! If the car won't start (like mine), jiggle the wire as you turn the ignition (many of these PassLock problems are old, corroded wire connections, not the Hall sensor).
5. Clip the yellow data wire, leaving at least some wire to work with on both sections. Once the wire is cut, you may (but don't have to) turn off the car.
6. From Radio Shack, obtain SPST mini-toggle switch # XXXXX (total cost including tax: $3.17).
7. Remove switch from packaging; make sure it is in the "off" (contacts open) position (check it with a meter).
8. Strip a short section of insulation from each end of the cut data wire, slip some shrink wrap over the wires, and splice in the switch.
9. Maneuver the shrink wrap over the soldered terminals and heat to form a completely insulated splice.
10. The toggle can be left inside the housing or mounted on the underside of the lower housing section (drill a 1/4-inch hole carefully so the plastic does not melt around the drill bit).
11. Reinstall lower housing (three screws) and tilt lever (you may want to use some locktite, but I didn't). If you opted for outside mounting, screw on the locknut for the switch.
12. Snap top half of housing in place.
13. If you turned the car off, turn it on to test. It should start right up.
